How to Fix CVE-2012-6708

To remediate this vulnerability, upgrade all affected Jquery dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

jquery fixed: 1.9.0 
npm install jquery@1.9.0
org.webjars.npm:jquery fixed: 1.9.0 
<dependency>
    <groupId>org.webjars.npm</groupId>
    <artifactId>jquery</artifactId>
    <version>1.9.0</version>
</dependency>
jQuery fixed: 1.9.0 
Upgrade jQuery to 1.9.0
jquery-rails fixed: 2.2.0 
Upgrade jquery-rails to 2.2.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls jquery

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2012-6708, inspect your project dependencies using npm:

npm ls jquery

Analyze the terminal output to locate any version of Jquery in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.9.0), your application is affected.

Note: The npm ls jquery command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-64: Windows Shortcut Following (.LNK), where the product, when opening a file or directory, does not sufficiently handle when the file is a windows shortcut (.lnk) whose target is outside of the intended control sphere. this could allow an attacker to cause the product to operate on unauthorized files. In Jquery, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Affected versions of `jquery` are vulnerable to cross-site scripting. This occurs because the main `jquery` function uses a regular expression to differentiate between HTML and selectors, but does not properly anchor the regular expression. The result is that `jquery` may interpret HTML as selectors when given certain inputs, allowing for client side code execution. ## Proof of Concept ``` $("#log").html( $("element[attribute='<img src=\"x\" onerror=\"alert(1)\" />']").html() ); ``` ## Recommendation Update to version 1.9.0 or later.
