0 CVE-2025-40931 affects Apache::Session::Generate::MD5 for Perl, which generates session IDs using an insecure method. The session IDs are created by hashing a combination of the built-in rand() function, epoch time, and process ID (PID) with MD5. Because rand() is not cryptographically secure, and the PID and epoch time can be guessed or inferred, the session IDs are predictable. This predictability could allow attackers to hijack sessions and gain unauthorized access. Some Debian-based distributions have patched this by replacing the generator with Crypt::URandom. No official patch or vendor advisory is provided for the original module. The vulnerability has a CVSS score of 9.1, indicating critical severity.
