CVE-2025-40932
HIGHCVSS Vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N
Lifecycle Timeline
2Description
Apache::SessionX versions through 2.01 for Perl create insecure session id. Apache::SessionX generates session ids insecurely. The default session id generator in Apache::SessionX::Generate::MD5 returns a MD5 hash seeded with the built-in rand() function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Predicable session ids could allow an attacker to gain access to systems.
Analysis
Apache\ versions up to \ contains a vulnerability that allows attackers to gain access to systems (CVSS 8.2).
