• Printf in assembler doesn't print

  - by Gaim

  Hi there, I have got a homework to hack program using buffer overflow ( with disassambling, program was written in C++, I haven't got the source code ). I have already managed it but I have a problem. I have to print some message on the screen, so I found out address of printf function, pushed address of "HACKED" and address of "%s" on the stack ( in this order ) and called that function. Called code passed well but nothing had been printed. I have tried to simulate the environment like in other place in the program but there has to be something wrong. Do you have any idea what I am doing wrong that I have no output, please? Thanks a lot EDIT: This program is running on Windows XP SP3 32b, written in C++, Intel asm there is the "hack" code CPU Disasm Address Hex dump Command Comments 0012F9A3 90 NOP ;hack begins 0012F9A4 90 NOP 0012F9A5 90 NOP 0012F9A6 89E5 MOV EBP,ESP 0012F9A8 83EC 7F SUB ESP,7F ;creating a place for working data 0012F9AB 83EC 7F SUB ESP,7F 0012F9AE 31C0 XOR EAX,EAX 0012F9B0 50 PUSH EAX 0012F9B1 50 PUSH EAX 0012F9B2 50 PUSH EAX 0012F9B3 89E8 MOV EAX,EBP 0012F9B5 83E8 09 SUB EAX,9 0012F9B8 BA 1406EDFF MOV EDX,FFED0614 ;address to jump, it is negative because there mustn't be 00 bytes 0012F9BD F7DA NOT EDX 0012F9BF FFE2 JMP EDX ;I have to jump because there are some values overwritten by the program 0012F9C1 90 NOP 0012F9C2 0090 00000000 ADD BYTE PTR DS:[EAX],DL 0012F9C8 90 NOP 0012F9C9 90 NOP 0012F9CA 90 NOP 0012F9CB 90 NOP 0012F9CC 6C INS BYTE PTR ES:[EDI],DX ; I/O command 0012F9CD 65:6E OUTS DX,BYTE PTR GS:[ESI] ; I/O command 0012F9CF 67:74 68 JE SHORT 0012FA3A ; Superfluous address size prefix 0012F9D2 2069 73 AND BYTE PTR DS:[ECX+73],CH 0012F9D5 203439 AND BYTE PTR DS:[EDI+ECX],DH 0012F9D8 34 2C XOR AL,2C 0012F9DA 2066 69 AND BYTE PTR DS:[ESI+69],AH 0012F9DD 72 73 JB SHORT 0012FA52 0012F9DF 74 20 JE SHORT 0012FA01 0012F9E1 3120 XOR DWORD PTR DS:[EAX],ESP 0012F9E3 6C INS BYTE PTR ES:[EDI],DX ; I/O command 0012F9E4 696E 65 7300909 IMUL EBP,DWORD PTR DS:[ESI+65],-6F6FFF8D 0012F9EB 90 NOP 0012F9EC 90 NOP 0012F9ED 90 NOP 0012F9EE 31DB XOR EBX,EBX ; hack continues 0012F9F0 8818 MOV BYTE PTR DS:[EAX],BL ; writing 00 behind word "HACKED" 0012F9F2 83E8 06 SUB EAX,6 0012F9F5 50 PUSH EAX ; address of "HACKED" 0012F9F6 B8 3B8CBEFF MOV EAX,FFBE8C3B 0012F9FB F7D0 NOT EAX 0012F9FD 50 PUSH EAX ; address of "%s" 0012F9FE B8 FFE4BFFF MOV EAX,FFBFE4FF 0012FA03 F7D0 NOT EAX 0012FA05 FFD0 CALL EAX ;address of printf This code is really ugly because I am new in assembler and there mustn't be null bytes because of buffer-overflow bug

• Lucene (.NET) Document stucture and performance suggestions.

  - by Josh Handel

  Hello, I am indexing about 100M documents that consist of a few string identifiers and a hundred or so numaric terms.. I won't be doing range queries, so I haven't dugg too deep into Numaric Field but I'm not thinking its the right choose here. My problem is that the query performance degrades quickly when I start adding OR criteria to my query.. All my queries are on specific numaric terms.. So a document looks like StringField:[someString] and N DataField:[someNumber].. I then query it with something like DataField:((+1 +(2 3)) (+75 +(3 5 52)) (+99 +88 +(102 155 199))). Currently these queries take about 7 to 16 seconds to run on my laptop.. I would like to make sure thats really the best they can do.. I am open to suggestions on field structure and query structure :-). Thanks Josh PS: I have already read over all the other lucene performance discussions on here, and on the Lucene wiki and at lucid imiagination... I'm a bit further down the rabbit hole then that...

• Web Shop Schema - Document Db

  - by Maxem

  I'd like to evaluate a document db, probably mongo db in an ASP.Net MVC web shop. A little reasoning at the beginning: There are about 2 million products. The product model would be pretty bad for rdbms as there'd be many different kinds of products with unique attributes. For example, there'd be books which have isbn, authors, title, pages etc as well as dvds with play time, directors, artists etc and quite a few more types. In the end, I'd have about 9 different products with a combined column count (counting common columns like title only once) of about 70 to 100 whereas each individual product has 15 columns at most. The three commonly used ways in RDBMS would be: EAV model which would have pretty bad performance characteristics and would make it either impractical or perform even worse if I'd like to display the author of a book in a list of different products (think start page, recommended products etc.). Ignore the column count and put it all in the product table: Although I deal with somewhat bigger databases (row wise), I don't have any experience with tables with more than 20 columns as far as performance is concered but I guess 100 columns would have some implications. Create a table for each product type: I personally don't like this approach as it complicates everything else. C# Driver / Classes: I'd like to use the NoRM driver and so far I think i'll try to create a product dto that contains all properties (grouped within detail classes like book details, except for those properties that should be displayed on list views etc.). In the app I'll use BookBehavior / DvdBehaviour which are wrappers around a product dto but only expose the revelent Properties. My questions now: Are my performance concerns with the many columns approach valid? Did I overlook something and there is a much better way to do it in an RDBMS? Is MongoDb on Windows stable enough? Does my approach with different behaviour wrappers make sense?

• Quick question regarding this issue, Why doesnt it print out the second value(converted second value

  - by sil3nt

  Quick question, What have I done wrong here. The purpose of this code is to get the input into a string, the input being "12 34", with a space in between the "12" and "32" and to convert and print the two separate numbers from an integer variable known as number. Why doesn't the second call to the function copyTemp, not produce the value 34?. I have an index_counter variable which keeps track of the string index and its meant to skip the 'space' character?? what have i done wrong? thanks. #include <stdio.h> #include <string.h> int index_counter = 0; int number; void copyTemp(char *expr,char *temp); int main(){ char exprstn[80]; //as global? char tempstr[80]; gets(exprstn); copyTemp(exprstn,tempstr); printf("Expression: %s\n",exprstn); printf("Temporary: %s\n",tempstr); printf("number is: %d\n",number); copyTemp(exprstn,tempstr); //second call produces same output shouldnt it now produce 34 in the variable number? printf("Expression: %s\n",exprstn); printf("Temporary: %s\n",tempstr); printf("number is: %d\n",number); return 0; } void copyTemp(char *expr,char *temp){ int i; for(i = index_counter; expr[i] != '\0'; i++){ if (expr[i] == '0'){ temp[i] = expr[i]; } if (expr[i] == '1'){ temp[i] = expr[i]; } if (expr[i] == '2'){ temp[i] = expr[i]; } if (expr[i] == '3'){ temp[i] = expr[i]; } if (expr[i] == '4'){ temp[i] = expr[i]; } if (expr[i] == '5'){ temp[i] = expr[i]; } if (expr[i] == '6'){ temp[i] = expr[i]; } if (expr[i] == '7'){ temp[i] = expr[i]; } if (expr[i] == '8'){ temp[i] = expr[i]; } if (expr[i] == '9'){ temp[i] = expr[i]; } if (expr[i] == ' '){ temp[i] = '\0'; sscanf(temp,"%d",&number); index_counter = i+1; //skips? } } // is this included here? temp[i] = '\0'; }

• IIS URL Rewrite rule - Default document for subdirectories

  - by Antonio Bakula

  I would like create URL rewrite rule that will set default document for my virtual folders. eg. someting like this www.domain.com/en/ -> www.domain.com/en/index.aspx www.domain.com/hr/ -> www.domain.com/hr/index.aspx www.domain.com/de/ -> www.domain.com/de/index.aspx directories en, hr, de doesn't really exists on web server they are just markers for languange used in site used by home grown http module that will rewrite path with query params. Quick solution was define rule for every single lang, something like this : <rewrite> <rewriteMaps> <rewriteMap name="Langs"> <add key="/en" value="/en/index.aspx" /> <add key="/hr" value="/hr/index.aspx" /> <add key="/de" value="/de/index.aspx" /> </rewriteMap> </rewriteMaps> <rules> But I would really like solution that would not require changes in web.config and adding rewrite rule for every languange used on particular site. Thanks !

• Validation error while putting <h> tag inside <a> tag(document type does not allow element "h2")

  - by makmour

  when using this code: <div class="menu"> <ul id="mainnav"> <li><h2><a href="dir1/" >AAAAA</a></h2> <ul> <li><a href="dir1/xxx.php"><h3>xxx</h3></a></li> <li><a href="dir1/xxx2.php"><h3>xxx2</h3></a></li> <li><a href="dir1/hxxx3.php"><h3>hxxx3</h3></a></li> </ul> </li> I get an error while validating saying that I should put <h2> outside of <a>. document type does not allow element <h2> When I do this validation passes without any problems but my styling breaks. Is there a way to keep both validation and styling? This is styling for menu and <h2> .menu li a{ font: 100% Helvetica, Arial, sans-serif; display:inline-block; color: #fff; } .menu li a:hover{ color: #014661; background: url('../images/menu1.png') center left no-repeat; } .menu li a h2{ font-size: 92%; padding: 8px 18px; font-weight: bold; text-transform: uppercase; } .menu h3{ font-size: 87%; font-weight: bold; text-transform: uppercase; } .menu li a h2:hover{ background: url('../images/menu2.png') center right no-repeat; }

• Is there a Word field code for the folder path?

  In MS Word you can insert a field code to show the document file name with the option to include or not the full path. What I want is to only insert the folder path excluding the file name. Macros are not an option. Can this be done?

• pyPDF - Retrieve page numbers from document

  - by SquidneyPoitier

  At the moment I'm looking into doing some PDF merging with pyPdf, but sometimes the inputs are not in the right order, so I'm looking into scraping each page for its page number to determine the order it should go in (e.g. if someone split up a book into 20 10-page PDFs and I want to put them back together). I have two questions - 1.) I know that sometimes the page number is stored in the document data somewhere, as I've seen PDFs that render on Adobe as something like [1243] (10 of 150), but I've read documents of this sort into pyPDF and I can't find any information indicating the page number - where is this stored? 2.) If avenue #1 isn't available, I think I could iterate through the objects on a given page to try to find a page number - likely it would be its own object that has a single number in it. However, I can't seem to find any clear way to determine the contents of objects. If I run: pdf.getPage(0).getContents() This usually either returns: {'/Filter': '/FlateDecode'} or it returns a list of IndirectObject(num, num) objects. I don't really know what to do with either of these and there's no real documentation on it as far as I can tell. Is anyone familiar with this kind of thing that could point me in the right direction?

• Best suited tool to document message processing done in C written program

  - by user3494614

  I am relatively new to UML and it's seems to be very vast I have a small program which basically receives messages on socket and then depending upon message ID embedded as first byte of message it processes the buffer. There are around 5 different message ID which it processes and communicates on another socket and has around 8 major functions. So program in short is like this. I am not pasting entire .c file or main function but just giving some bits and pieces of it so that to get idea of program flow. int main(int argc, char** argv) { register_shared_mem(); listen(); while(get_next_message(buffer)) { switch((msg)(buffer)->id) { case TYPE1: process1(); answer(); ..... } } } I want to document this is pictorial way like for Message type 1 it calls this function which calls another and which calls another. Please let me know any open source tool which will allow me to quickly draw such kind of UML or sequence diagram and will also allow me to write brief description of what each function does? Thanks In Advance

• Converting a soap message to a document using wssj

  - by ellander

  I have been supplied with a jar file that should enable me to connect to a 3rd party system. When I run the necessary class I get an error which states that the namespace for the prefix "SOAPENV" has not been declared. Using jad I have decompiled the class files to try suss out what is going on and the error seems to occur when a soap message is being converted to a document. Unfortunately I don't know much about wssj. Can anyone suggest what the problem might be? I'm wondering if it's an incompatibility issue as it's not a recently created jar file and the decompiled code looks different to all the examples I can find. For example, in this section the examples have addNamesSpaceDeclaration rather than addAttribute... MessageFactory factory = MessageFactory.newInstance(); SOAPFactory sf = SOAPFactory.newInstance(); SOAPMessage msg = factory.createMessage(); MimeHeaders headers = msg.getMimeHeaders(); headers.addHeader("Content-Type", "text/xml"); SOAPEnvelope env = msg.getSOAPPart().getEnvelope(); env.addAttribute(sf.createName("xmlns:xsi"), "http://www.w3.org/2001/XMLSchema-instance");

• DynamicContent.html: Write a JavaScript in an HTML document that can change the content of an HTML e

  - by A sw A

  ShowHide.html: Write a JavaScript in an HTML document that displays an image and allows the user to toggle the image between appearing and not appearing in the document. Place your image in a (division) tag that has a style attribute. “style.visibility” can take two values: “visible” and “hidden”. The document has a button called “Toggle Image”, which calls the toggle function upon the event “onclick”. DynamicColors.html: Write a JavaScript in an HTML document that changes the background and foreground colors of the body of a document according to the user input. The document has two input texts: background color and foreground color. The colors change when the event “onchange” occurs as you type in the text input and the event handler is called. Your event handler takes two parameters: “where”, and “newColor”. To change the document color and background color you need to change the elements document.body.style.color and document.body.style.backgroundColor. Available colors are: black, silver, gray, white, maroon, red, purple, fuchsia, green, lime, olive, yellow, navy, blue, teal, and aqua. DynamicContent.html: Write a JavaScript in an HTML document that can change the content of an HTML element (a help box). The content of an element is accessed through its “value” property. The content of a help box can change depending on the placement of the mouse cursor. When the cursor is placed over a particular input field (“onmouseover” event), the help box can display advice on how the field is to be filled. When the cursor is moved away from the input field (“onmouseout” event), the help box content changes to simply indicate that assistance is available. Your messages are stored in an array of strings.

• How to create a Global Rule that stores a document’s folder path in a custom metadata field

In real life, we are willing to pay a price for performance –i.e. to have information at our fingertips. We have run into customers opting to store a document folder path as a document metadata field. They have their reasons, half of the ECM community will agree with them, and the other half would raise an eye brow. In the end, they are getting creative to achieve their document management goals. The below steps outlines how to create a Global Rule that would store a document’s folder path in a custom metadata field: Create a Global Rule via Configuration Manager > Rules Tab > Add Then check “Is global rule with priority”. Then check “Use rule activation condition”. The go to “Edit” and check the actions for this Script Properties: Then click OK, and the following rule activation condition will appear: Then Goto to the Fields Tab and add a Rule Field: Select the target Custom Metadata Field and click Ok, then check the “Is derived field”, then “Edit”, then go to the Custom Tab in the Script Properties window and enter the below custom script: <$if #active.dCollectionPath$> <$dprDerivedValue=#active.dCollectionPath$> <$else$> <$dprDerivedValue=#active.xCollectionIDPath$> <$endif$> For more information on the dCollectionPath property, check Section 8.2 Folder Services from the Oracle® Fusion Middleware Services Reference Guide for Oracle Universal Content Management 11g Release 1 (11.1.1) http://docs.oracle.com/cd/E21043_01/doc.1111/e11011/c08_folders002.htm The above rule will keep the Custom Metadata Field updated with the Folder Path information when a document is checked in via the Content Server (CS) Web Interface or the Desktop Integration Suite (DIS).

• Looking for streaming xml pretty printer in C/C++ using expat or libxml2

  - by Mark Zeren

  I'm looking for a streaming xml pretty printer for C/C++ that's either self contained or that uses libxml2 or expat. I've searched a bit and not found one. It seems like something that would be generally useful. Am I missing an obvious tool that does this? Background: I have a library that outputs xml without whitespace all on one line. In some cases I'd like to pretty print that output. I'm looking for a BSD-ish licensed C/C++ library or sample code that will take a raw xml byte stream and pretty print it. Here's some pseudo code showing one way that I might use this functionality: void my_write(const char* buf, int len); PrettyPrinter pp(bind(&my_write)); while (...) { // ... get some more xml ... const char* buf = xmlSource.get_buf(); int len = xmlSource.get_buf_len(); int written = pp.write(buf, len); // calls my_write with pretty printed xml // ... error handling, maybe call write again, etc. ... } I'd like to avoid instantiating a DOM representation. I already have dependencies on the expat and libxml2 shared libraries, and I'd rather not add any more shared library dependencies.

• Printing HTML blocks

  - by Lem0n

  I have a page with a few tables that I want to be printable. I want the following behaviour: 1) Add a page break if the next table fits in a single page, but won't fit in the current page (because of other stuff already printed on this page) 2) Print the "table header" again in case it's needed to break a table (I guess it's the default behaviour) Any ideas specially on the first issue? Maybe some CSS can help? I'll give on example. I have a page with 4 tables. All of them with 10 lines, except the third one, with 50 lines. The first and second goes on the first page. Since the third one won't fit in the same page, but will fit in a page alone, it's printed on a page alone... and then the forth table is printed on the third page (in case it doesn't fit together in the second page). But, if the third page had 300 lines and would be broke anyway, it could have started to be print in the first page.

• streaming xml pretty printer in C/C++ using expat or libxml2?

  - by Mark Zeren

  I have a library that outputs xml without whitespace all on one line. In some cases I'd like to pretty print that output. I'm looking for a BSD-ish licensed C/C++ library or sample code that will take a raw xml byte stream and pretty print it. Here's some pseudo code showing one way that I might use this functionality: void my_write(const char* buf, int len); PrettyPrinter pp(bind(&my_write)); while (...) { // ... get some more xml ... const char* buf = xmlSource.get_buf(); int len = xmlSource.get_buf_len(); int written = pp.write(buf, len); // calls my_write with pretty printed xml // ... error handling, maybe call write again, etc. ... } I'd like to avoid instantiating a DOM representation. I already have dependencies on the expat and libxml2 shared libraries, and I'd rather not add any more shared library dependencies.

• Printer Sharing with FreeNAS

  - by Unkwntech

  I am using FreeNAS on my lan to do some file/iTunes sharing but I'd like to add printer sharing to it so that I can stop using a second (aging windows) system. I'm not familiar with BSDs but I am comfortable with the shell (I'm a Debian admin) are there any good tutorials for setting up printer sharing (cups?) on FreeNAS?

• What does the "Enable Advanced Printing Features" option do?

  - by Ben McCormack

  When I go to look at a printer's properties in Windows XP, I see a checkbox for "Enable Advanced Printing Features." What does this option do? (Specifically, I'm using a Zebra S4M label printer, but I believe this option is available for printers throuh the "printer properties" dialog in Windows).

• Sharing a printer over the net from Windows 7 to Windows Server 2003

  - by Grant Unwin

  Hi, I need to share a printer that is connected to a Windows 7 computer. The windows 7 computer is in another building about an hours drive away. The computer that needs to access the printer is running Windows Server 2008. Ive tried setting the printer as 'shared' for 'everyone' on the Windows 7 PC and accessing it from the server by adding a TCP/IP port to the IP address but the printer just wont add. From googling aparently it may need setting up as a printer server through IIS, but i'm just not sure on the best practice. Any help greatly appreciated. Thanks Grant Unwin
