Executive Summary

This vulnerability involves a flaw where a browser extension manipulates page records during indexing, forcing restrictions that are then stored in a shared cache. This allows unauthorized users to bypass access controls on cached pages.

Detection Guidance

Check if your TYPO3 instance uses the vulnerable 'Apache Solr for TYPO3 - Enterprise Search' extension versions (11.6.5 or below, 12.0.0 to 12.1.3, or 13.0.0 to 13.1.3). Inspect extension versions via TYPO3 backend or by checking the composer.json file. Verify if anonymous users can access restricted content or manipulate cached pages.

Impact Analysis

It could let attackers access restricted content without proper permissions, potentially exposing sensitive data to unauthorized users through cached pages.

Compliance Impact

This vulnerability allows anonymous users to bypass access restrictions and retrieve documents without proper filters, which could lead to unauthorized access to sensitive data. This may violate compliance requirements under GDPR (data protection) and HIPAA (health information privacy) by exposing personal or confidential information to unauthorized parties.

Mitigation Strategies

Clear the shared rootline cache to remove the forged state and disable caching of page records during indexer sub-requests until a patch is applied.
