Trustix httpsd Permissions Risk

A new advisory highlights a dangerous misconfiguration in Trustix that installs the Apache-SSL httpsd binary with world-writeable permissions. Local users can swap the executable with a Trojan horse, enabling privilege escalation or credential theft the moment the service restarts. Administrators should immediately check file ownership on httpsd, reset permissions to a restrictive 0755, and verify package integrity against trusted repositories before bringing the service back online.

Cyvex recommends auditing other binaries installed by third-party packages for similar issues, monitoring systemd or init scripts for unexpected restarts, and enabling file integrity monitoring to catch tampering early. If compromise is suspected, replace the affected package from a clean source and review logs for lateral movement attempts, as attackers often use web server footholds to pivot deeper into the network.
