Summary

Symfony vulnerable to Session Fixation of CSRF tokens

Details

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 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 for branch 4.4.

Credits

We would like to thank Marco Squarcina for reporting the issue and Nicolas Grekas for fixing it.

CVE-2022-24895 (GCVE-0-2022-24895)

Vulnerability from cvelistv5 – Published: 2023-02-03 21:45 – Updated: 2025-03-10 21:16

Title

Symfony vulnerable to Session Fixation of CSRF tokens

Summary

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. 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 to bypass the CSRF protection mechanism by performing an attack similar to a session-fixation. This issue has been fixed in the 4.4 branch.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
