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, 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

Online Media Asset Handling (*`.youtube` and *`.vimeo` files) in the TYPO3 backend is vulnerable to denial of service. Putting large files with according file extensions results in high consumption of system resources. This can lead to exceeding limits of the current PHP process which results in a dysfunctional backend component. A valid backend user account or write access on the server system (e.g. SFTP) is needed in order to exploit this vulnerability.
