CVE-2025-40923 (GCVE-0-2025-40923)
Vulnerability from nvd – Published: 2025-07-16 13:05 – Updated: 2025-11-04 21:10

Title
Plack-Middleware-Session before version 0.35 for Perl generates session ids insecurely
Summary
Plack-Middleware-Session before version 0.35 for Perl generates session ids insecurely.
The default session id generator returns a SHA-1 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.
