CVE-2025-59015: TYPO3 CMS uses insufficient entropy when generating passwords

A deterministic three‑character prefix in the Password Generation component of TYPO3 CMS versions 12.0.0–12.4.36 and 13.0.0–13.4.17 reduces entropy, allowing attackers to carry out brute‑force attacks more quickly.

Root Cause Analysis

The vulnerability, as described, is due to insufficient entropy in password generation, leading to a predictable prefix. The analysis of the provided commit d2057cc7b2c2db417a2af38c30cb9da42302ab70 confirms this. The patch directly targets the generateRandomPassword function in the TYPO3\CMS\Core\Crypto\Random class. The core of the vulnerability lies in the predictable way the initial characters of the password were generated, followed by an insecure shuffling method (str_shuffle). The fix involves replacing str_shuffle() with a cryptographically secure alternative, (new Randomizer())->shuffleBytes(), to ensure the final password is not predictable. Therefore, the generateRandomPassword function is the single point of failure and the function that would be observed in a runtime profile during the password generation process that is being exploited.
