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/security-bundle

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-24895, inspect your project dependencies for Symfony/security bundle:

inspect dependencies for symfony/security-bundle

Analyze the terminal output to locate any version of Symfony/security bundle in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.4.50), 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-613: Insufficient Session Expiration, where according to wasc, "insufficient session expiration is when a web site permits an attacker to reuse old session credentials or session ids for authorization.". In Symfony/security 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

Description ----------- When authenticating users Symfony by default regenerates the session ID upon login, but preserves the rest of session attributes. Because this does not clear CSRF tokens upon login, this might enables [same-site attackers](https://canitakeyoursubdomain.name/) to bypass the CSRF protection mechanism by performing an attack similar to a session-fixation. Resolution ---------- Symfony removes all CSRF tokens from the session on successful login. The patch for this issue is available [here](https://github.com/symfony/symfony/commit/5909d74ecee359ea4982fcf4331aaf2e489a1fd4) for branch 4.4. Credits ------- We would like to thank Marco Squarcina for reporting the issue and Nicolas Grekas for fixing it.
