GHSA-hjx5-v9xg-7h25: TYPO3 Denial of Service in Frontend Record Registration

TYPO3’s built-in record registration functionality (aka “basic shopping cart”) using recs URL parameters is vulnerable to denial of service. Failing to properly ensure that anonymous user sessions are valid, attackers can use this vulnerability in order to create an arbitrary amount of individual session-data records in the database.

Root Cause Analysis

The vulnerability stems from processing the 'recs' URL parameter in TYPO3's frontend controller. The commit introduced a configuration flag to disable this functionality, indicating the vulnerable code path was directly handling 'recs' parameter input. The TypoScriptFrontendController is responsible for frontend request processing, and its URL parameter handling method would be the logical place where session data from 'recs' was processed without proper throttling or authentication checks. The high confidence comes from the patch's focus on disabling this feature via configuration, implying the unpatched code lacked these safeguards in the parameter processing logic.
