Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Typo3/cms core, 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

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.
