How to Fix CVE-2014-4931

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

symfony/framework-bundle fixed: 2.3.18
Upgrade symfony/framework-bundle to 2.3.18
symfony/framework-bundle fixed: 2.4.8
Upgrade symfony/framework-bundle to 2.4.8
symfony/framework-bundle fixed: 2.5.2
Upgrade symfony/framework-bundle to 2.5.2
symfony/symfony fixed: 2.3.19
Upgrade symfony/symfony to 2.3.19
symfony/symfony fixed: 2.4.9
Upgrade symfony/symfony to 2.4.9
symfony/symfony fixed: 2.5.4
Upgrade symfony/symfony to 2.5.4
Verify Direct and Transitive Dependencies

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

inspect dependencies for symfony/framework-bundle

How to Check if You Are Affected

To determine whether your application is affected by CVE-2014-4931, inspect your project dependencies for Symfony/framework bundle:

inspect dependencies for symfony/framework-bundle

Analyze the terminal output to locate any version of Symfony/framework bundle in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.18), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Symfony/framework bundle, 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

When investigating issue [#11093](https://github.com/symfony/symfony/issues/11093), [Jeremy Derussé](https://connect.sensiolabs.com/profile/jderusse) found a serious code injection issue in the way Symfony implements translation caching in FrameworkBundle. - Your Symfony application is vulnerable if you meet the following conditions: - You are using the Symfony translation system from FrameworkBundle (so basically if you are using Symfony full-stack -- you are not affected if you are using the Translation component with Silex for instance); You don't sanitize locales coming from a URL (any route with a _locale argument for instance): When vulnerable, an attacker can submit a non-valid locale value that can contain some PHP code that will be executed by Symfony. That's because the locale value is dumped into a PHP file generated in the cache without being sanitized first.
