Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. 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

The backend login has a basic brute force protection implementation which pauses for 5 seconds if wrong credentials are given. This pause however could be bypassed by forging a special request, making brute force attacks on backend editor credentials more feasible.
