CyberRota Analysis

AI-Generated

The vulnerability affects OpenSSL within TYPO3, where system information is transmitted in cleartext when OpenSSL is unavailable, potentially exposing sensitive data. An attacker must already possess control of the SYSSY project's API key to exploit this weakness. Organizations using TYPO3 with OpenSSL should prioritize remediation to safeguard against potential information leakage.

Original NVD Description

When OpenSSL is unavailable on the server, the extension transmits TYPO3 system information in cleartext instead of encrypting it. Exploitation requires the attacker to already be in control of the SYSSY project's API key.
