Summary
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.
Risk Assessment
If an attacker intercepts network traffic, they can obtain sensitive system information, potentially facilitating further attacks.
Recommendation
Ensure OpenSSL is installed and available on the server, or update the extension to a version that enforces encryption.
