  • Prevent SQL injection from form-generated SQL - NO PreparedStmts

    - by Markos Fragkakis
    Hi all, I have a search table where user will be able to filter results with a filter of the type: Field [Name], Value [John], Remove Rule Field [Surname], Value [Blake], Remove Rule Field [Has Children], Value [Yes], Remove Rule Add Rule So the user will be able to set an arbitrary set of filters, which will result essentially in a completely dynamic WHERE clause. In the future I will also have to implement more complicated logical expressions, like Where (name=John OR name=Nick) AND (surname=Blake OR surname=Bourne), Of all 10 fields the user may or may not filter by, I don't know how many and which filters the user will set. So, I cannot use a prepared statement (which assumes that at least we know the fields in the WHERE clause). This is why prepared statements are unfortunately out of the question, I have to do it with plain old, generated SQL. What measures can I take to protect the application from SQL Injection (REGEX-wise or any other way)?

  • How to get --detect-branches to work with git-p4?

    - by Michael Brennan
    My p4 repository has a structure similar to: //depot/project/branch1 //depot/project/branch2 //depot/project/branch3 ... etc However, when I use git-p4 to clone "project", all 3 branches are not considered as branches and all get cloned into the single master branch. This is how I'm invoking git-p4: git-p4 clone --detect-branches //depot/project I was expecting git-p4 to create a git database for "project" with three branches, and the root of the project would be mapped to the portion of the path after the branch name (for example: if //depot/project/branch1 has a subdirectory called "lib" (//depot/project/branch1/lib) then my local file system should be something like /git_project/lib with 3 git branches). Is what I'm expecting wrong? Am I invoking git-p4 incorrectly?

  • Colorbox not working in IE

    - by John Isaacks
    on This page in the center is a button that says "request price". I am using Colorbox so that when you click it, there is a lightbox-type popup of a Flash app. This works fine in FF and Chrome. However in IE it is just taking you directly to the page containing the flash rather then making it a popup. Does anyone have a clue why?

  • onmouseover with django / imagekit

    - by Michael Moreno
    I'm using Imagekit. View.py includes: def pics(request): p = Photo.objects.all() return render_to_response('Shots.html', {'p': p}) The following simple code in the template will generate associated images: {% for p in p %} <img src = "{{ p.display.url }}"> <img src = "{{ p.thumbnail_image.url }}"> {% endfor %} I'm attempting to generate a series of thumbnails {{ p.thumbnail_image.url }} which, when mouseover'd, will generate the slightly larger version of the image, {{ p.display.url }} via Javascript. The following code in the template attempts to do so: <html> <head> <HEAD> <script language="Javascript"> { image1 = new Image image2 = new Image image1.src = {{ p.thumbnail_image.url }} image2.src = {{ p.display.url }} </script> </head> <body> {% for p in p %} <a href="" onMouseOver="document.rollover.src= image2.src onMouseOut="document.rollover.src= image1.src"> <img src="{{ p.thumbnail_image.url }}" border=0 name="rollover"></a> {% endfor %} </body> </html> This will display the series of thumbnails, but the larger image will not display when mouseover'd. I believe it has to do with how I'm specifying the variable {{ p.display.url }}.

  • JNDI / Classpath problem in glassfish

    - by Michael Borgwardt
    I am in the process of converting a large J2EE app from EJB 2 to EJB 3 (all stateless session beans, using glassfish 2.1.1), and running out of ideas. The first EJB I converted (let's call it Foo) ran without major problems (it was the only one in its ejb-module and I could completely replace the deployment descriptor with annotations) and the app ran fine. But after converting the second one (let's call it Bar, one of several in a different ejb-module) there is a weird combination of problems: The app deploys without errors (nothing in the logs either) There is an error when looking up Bar via JNDI When looking at the JNDI tree in the glassfish admin console, Bar is not present at all. Then when I look at the logs, I see this (Foo is the correct name of the EJB's remote interface of the first converted, previously working EJB): Caused by: javax.naming.NamingException: ejb ref resolution error for remote business interface Foo [Root exception is java.lang.ClassNotFoundException: Foo] at com.sun.ejb.EJBUtils.lookupRemote30BusinessObject(EJBUtils.java:425) at com.sun.ejb.containers.RemoteBusinessObjectFactory.getObjectInstance(RemoteBusinessObjectFactory.java:74) at javax.naming.spi.NamingManager.getObjectInstance(NamingManager.java:304) at com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:414) at com.sun.enterprise.naming.SerialContext.list(SerialContext.java:603) at javax.naming.InitialContext.list(InitialContext.java:395) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanHelper.getJndiEntriesByContextPath(JndiMBeanHelper.java:106) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanImpl.getNames(JndiMBeanImpl.java:231) ... 68 more Caused by: java.lang.ClassNotFoundException: XXX at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1578) at com.sun.ejb.EJBUtils.getBusinessIntfClassLoader(EJBUtils.java:679) at com.sun.ejb.EJBUtils.lookupRemote30BusinessObject(EJBUtils.java:348) ... 75 more This is followed by more exceptions for all the entries that (like Foo) do appear in the JNDI tree. These look like this: Caused by: javax.naming.NotContextException: BarHome cannot be listed at com.sun.enterprise.naming.SerialContext.list(SerialContext.java:607) at javax.naming.InitialContext.list(InitialContext.java:395) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanHelper.getJndiEntriesByContextPath(JndiMBeanHelper.java:106) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanImpl.getNames(JndiMBeanImpl.java:231) ... 68 more However, no exception for Bar, it does not appear in the log at all except one entry during deployment. The other EJBs in the same module do appear, as does Foo. Any ideas what could cause this or how to diagnose it further? The beans are pretty straightforward: @Stateless(name = "Foo") @RolesAllowed("FOOUSER") @TransactionAttribute(TransactionAttributeType.SUPPORTS) public class FooImpl extends BaseBean implements Foo { I'm also having some problems with the deployment descriptor for Bar (I'd like to eliminate it, but glassfish doesn't seem to like having a bean appear only in sun-ejb-jar.xml, or having some beans in a module declared in the descriptor and others use only annotations), but I can't see how that could cause the ClassNotFoundException on Foo. Is there a way to see the ClassPath that Glassfish is actually using?

  • Twitter Oauth Strategy with Warden + Devise Authentication Gems for Ruby

    - by Michael Waxman
    Devise, the authentication gem for Ruby based on Warden (another auth gem) does not support Twitter Oauth as an authentication strategy, BUT Warden does. There is a way to use the Warden Twitter Oauth strategy within Devise, but I cannot figure it out. I'm using the following block in the devise config file: config.warden do |manager| manager.oauth(:twitter) do |twitter| twitter.consumer_secret = <SECRET> twitter.consumer_key = <KEY> twitter.options :site => 'http://twitter.com' end manager.default_strategies.unshift :twitter_oauth end But I keep on getting all sorts of error messages. Does anyone know how to make this work? I'm assuming there is more to do here (configuring a new link/route to talk to Warden, maybe adding attributes to the Devise User model, etc.), but I can't figure out what they are. Please help.

  • Django Custom Widget For ManyToMany field

    - by John
    Does anyone know of a widget that displays 2 select boxes. One shows a list of all object in a model and the other shows the objects which have been selected. The user can then select an object from the first list, click an button which moves it to the 'selected' list. Then when the form is saved the objects in the selected list are saved in the manytomany field. Thanks

  • Proggraming a VPN, Authontication stage - RFC not clear enough

    - by John
    I have a custom build of a unix OS. My task: Adding an IPSec to the OS. I am working on Phase I, done sending the first 2 packets. what I am trying to do now is making the Identefication Payload. I've been reading RFC 2409 (Apendix B) which discuss the keying materials (SKEYID, SKEYID_d, SKEYID_a, SKEYID_e and the IV making). Now, I use SHA1 for authontication and thus I use HMAC-SHA1 & my encryption algorithem is AES 256bit. The real problem is that the RFC is not clear enough of what should I do regarding the PRF. It says: "Use of negotiated PRFs may require the PRF output to be expanded due to the PRF feedback mechanism employed by this document." I use SHA1, does it mean I do not negotiate a PRF? In my opinion, AES is the only algorithm that needs expention (a fixed length of 256bit), so, do i need to expand only the SKEYID_e? If you happen to know a clearer, though relible, source then the RFC please post a link. Thanks in advance!

  • $.Post with Form submit

    - by Michael
    ...Some form gets submitted... $.("form").submit(function() { saveFormValues($(this), "./../.."; } function saveFormValues(form, path) { var inputs = getFormData(form); var params = createAction("saveFormData", inputs); var url = path + "/scripts/sessions.php"; $.post(url, params); } The weird thing is that if i add a function to the $.post(url, params, function(data) { alert(data); } I get a blank alert statement. Within scripts/sessions.php i have a function to save whatever the $_POST information is to a file, and the sessions.php never saves this saveFormValues call. It never shows up to the file. But if i keep trying to get it to save, about once every 15 will actually allow it to be saved. This leads me to believe that the forms POST is somehow blocking this value saving post. Any help?

  • Spatial index for geo coordinates?

    - by Michael Borgwardt
    What kind of data structure could be used for an efficient nearest neighbor search in a large set of geo coordinates? With "regular" spatial index structures like R-Trees that assume planar coordinates, I see two problems (Are there others I have overlooked?): Wraparound at the poles and the International Date Line Distortion of distances near the poles How can these factors be allowed for? I guess the second one could compensated by transforming the coordinates. Can an R-Tree be modified to take wraparound into account? Or are there specialized geo-spatial index structures?

  • Canvas context used but not updated on canvas

    - by John Doe
    I am developing an small html5 game, where I have the following code: if(object.blocks){ var blocks = object.blocks, that = this; each(blocks,function(index){ that.blocks.push(new Block(this[index])); }); } I receive an object with some configuration and instantiate blocks with it. It works fine, but the Block class has an method, called draw: this.draw = function (ctx){ if(ctx){ var colors = ['#FF0000','#FFFF00','#0000FF','#00FF00'], color = Math.round(Math.random() * colors.length-1); ctx.fillStyle = colors[color]; ctx.fillRect(this.x,this.y,this.width,this.height); } }; It was working before I moved it into the Block class, but now it draws nothing. This is the code that calls draw: render: function(ctx){ each(this.blocks,function(index){ this[index].draw(ctx); }); } The context comes from the html page, from the main canvas.

  • UIWebView paging / line cut off

    - by John
    Hi, I am trying to page a webpage, so disable scrolling, then the second page is the same webpage scrolled down the page height. The problem I have is that the bottom of the first page often has 1/2 a line of text, then the second page has the bottom half of the line. Is there a way to ensure the entire line falls on one of the pages? Similar to Stanza etc? Thanks

  • Blank Pages with Zen Cart v1.3.8 and PHP 5.3

    - by Michael Soriano
    I am trying to run a live Zen Cart store (version 1.3.8) on a my local machine which is PHP 5.3. I am aware of the incompatibilities between both versions and have dealt with it by applying the patch found here: http://www.zen-cart.com/forum/showthread.php?t=140960 I am able to login the admin side no problem, but when i navigate to the store - all i see are blank pages. How can I fix this issue? I'm hoping there is a fix elsewhere. Trying not to revert to an older PHP installation.

  • What’s the strategy to recover data during DAO unit test?

    - by Michael Lu
    When I test DAO module in JUnit, an obvious problem is: how to recover testing data in database? For instance, a record should be deleted in both test methods testA() and testB(), that means precondition of both test methods need an existing record to be deleted. Then my strategy is inserting the record in setUp() method to recover data. What’s your better solution? Or your practical idea in such case? Thanks

  • How can I set a local branch to pull / merge from a particular remote branch?

    - by John
    I have a local branch foo that started life as a branch off of master. Then I pushed it to my remote, and it's now happily living life with its siblings in remotes/origin I want pull to automatically pull from remotes/origin/foo, and I want status -sb to show me how many changes I am ahead of remotes/origin/foo. I thought the way to do this was git config branch.foo.merge 'refs/heads/foo' However, after doing that, I get this message: ? git status -sb ## foo ? git pull Your configuration specifies to merge with the ref 'foo' from the remote, but no such ref was fetched. What am I doing wrong?

  • IIS7 Web.Config Custom Errors

    - by Michael
    Using GoDaddy to host my site (I know that's my first problem)! :-) Trying to setup customer error messages for my site. GoDaddy allows you to setup a 404 in their control panel, but I can't override this, or setup any additional error redirects, specifically a 500-server error. Here is my web.config file: <configuration> <system.webServer> <rewrite> <rules> <rule name="Redirect to WWW" stopProcessing="true"> <match url=".*" /> <conditions> <add input="{HTTP_HOST}" pattern="^mysite.com$" /> </conditions> <action type="Redirect" url="http://www.mysite.com/{R:0}" redirectType="Permanent" /> </rule> </rules> </rewrite> </system.webServer> <system.web> <customErrors mode="On" defaultRedirect="http://www.mysite.com/oops.php"> <error statusCode="404" redirect="http://www.mysite.com/oops.php?error=404" /> <error statusCode="500" redirect="http://www.mysite.com/oops.php?error=500" /> </customErrors> </system.web> </configuration>

  • XML to be validated against multiple xsd schemas

    - by Michael Rusch
    I'm writing the xsd and the code to validate, so I have great control here. I would like to have an upload facility that adds stuff to my application based on an xml file. One part of the xml file should be validated against different schemas based on one of the values in the other part of it. Here's an example to illustrate: <foo> <name>Harold</name> <bar>Alpha</bar> <baz>Mercury</baz> <!-- ... more general info that applies to all foos ... --> <bar-config> <!-- the content here is specific to the bar named "Alpha" --> </bar-config> <baz-config> <!-- the content here is specific to the baz named "Mercury" --> </baz> </foo> In this case, there is some controlled vocabulary for the content of <bar>, and I can handle that part just fine. Then, based on the bar value, the appropriate xml schema should be used to validate the content of bar-config. Similarly for baz and baz-config. The code doing the parsing/validation is written in Java. Not sure how language-dependent the solution will be. Ideally, the solution would permit the xml author to declare the appropriate schema locations and what-not so that s/he could get the xml validated on the fly in a sufficiently smart editor. Also, the possible values for <bar> and <baz> are orthogonal, so I don't want to do this by extension for every possible bar/baz combo. What I mean is, if there are 24 possible bar values/schemas and 8 possible baz values/schemas, I want to be able to write 1 + 24 + 8 = 33 total schemas, instead of 1 * 24 * 8 = 192 total schemas. Also, I'd prefer to NOT break out the bar-config and baz-config into separate xml files if possible. I realize that might make all the problems much easier, as each xml file would have a single schema, but I'm trying to see if there is a good single-xml-file solution.

  • CURL Authentication being lost?

    - by John Sloan
    I am authenticating a login via CURL just fine. I have a variable I am using to display the returned HTML, and it is returning my user control panel as if I am logged in. After authenticating, I want to communicate variables with a form on another page within the site; but for some reason the HTML from that page is returning a non-authenticated version of the header (as if the original authentication never took place.) I have a cookies.txt file with 777 permissions, and have tried just getting the contents of the same page shown when I authenticate and it is as if I am losing any associated session/cookie data somewhere along the way. Here is my curl.class file - <? class Curl { public $cookieJar = ""; // Make sure the cookies.txt file is read/write permissions public function __construct($cookieJarFile = 'cookies.txt') { $this->cookieJar = $cookieJarFile; } function setup() { $header = array(); $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,"; $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; $header[] = "Cache-Control: max-age=0"; $header[] = "Connection: keep-alive"; $header[] = "Keep-Alive: 300"; $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; $header[] = "Accept-Language: en-us,en;q=0.5"; $header[] = "Pragma: "; // browsers keep this blank. curl_setopt($this->curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7'); curl_setopt($this->curl, CURLOPT_HTTPHEADER, $header); curl_setopt($this->curl, CURLOPT_COOKIEJAR, $this->cookieJar); curl_setopt($this->curl, CURLOPT_COOKIEFILE, $this->cookieJar); curl_setopt($this->curl, CURLOPT_AUTOREFERER, true); curl_setopt($this->curl, CURLOPT_COOKIESESSION, true); curl_setopt($this->curl, CURLOPT_FOLLOWLOCATION, true); curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, true); } function get($url) { $this->curl = curl_init($url); $this->setup(); return $this->request(); } function getAll($reg, $str) { preg_match_all($reg, $str, $matches); return $matches[1]; } function postForm($url, $fields, $referer = '') { $this->curl = curl_init($url); $this->setup(); curl_setopt($this->curl, CURLOPT_URL, $url); curl_setopt($this->curl, CURLOPT_POST, 1); curl_setopt($this->curl, CURLOPT_REFERER, $referer); curl_setopt($this->curl, CURLOPT_POSTFIELDS, $fields); return $this->request(); } function getInfo($info) { $info = ($info == 'lasturl') ? curl_getinfo($this->curl, CURLINFO_EFFECTIVE_URL) : curl_getinfo($this->curl, $info); return $info; } function request() { return curl_exec($this->curl); } } ?> And here is my curl.php file - <? include('curl.class.php'); // This path would change to where you store the file $curl = new Curl(); $url = "http://www.site.com/public/member/signin"; $fields = "MAX_FILE_SIZE=50000000&dado_form_3=1&member[email]=email&member[password]=pass&x=16&y=5&member[persistent]=true"; // Calling URL $referer = "http://www.site.com/public/member/signin"; $html = $curl->postForm($url, $fields, $referer); echo($html); ?> <hr style="clear:both;"/> <? $html = $curl->postForm('http://www.site.com/index.php','nid=443&sid=733005&tab=post&eval=yes&ad=&MAX_FILE_SIZE=10000000&ip=63.225.235.30','http://www.site.com/public/member/signin'); echo $html; // This will show you the HTML of the current page you and logged into ?> Any ideas?

  • Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key"

    - by Michael Rosario
    Hello world. Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key" scheme? Problem facts: I am using Oracle XE. I have implemented the following table and trigger: CREATE TABLE "USERS" ( "ID" NUMBER(38,0), "USER_NAME" VARCHAR2(50), "PASSWORD" VARCHAR2(50), "EMAIL" VARCHAR2(100), CONSTRAINT "USERS_PK" PRIMARY KEY ("ID") ENABLE ) / CREATE OR REPLACE TRIGGER "BI_USERS" before insert on "USERS" for each row begin select "USERS_SEQ".nextval into :NEW.ID from dual; end; / ALTER TRIGGER "BI_USERS" ENABLE / MyGeneration / Doodads created the following stored proc... CREATE OR REPLACE PROCEDURE "XXX"."PI_USERS" ( p_ID IN USERS.ID%type, p_USER_NAME IN USERS.USER_NAME%type, p_PASSWORD IN USERS.PASSWORD%type, p_EMAIL IN USERS.EMAIL%type ) IS BEGIN INSERT INTO USERS ( ID, USER_NAME, PASSWORD, EMAIL ) VALUES ( p_ID, p_USER_NAME, p_PASSWORD, p_EMAIL ); END PI_USERS; The sequence and trigger combination is working fine. The BusinessEntity class in C# does not receive the new ID. Any recommended ways to allow the calling code receive the new record ID?
