Vulnerability from github – Published: 2025-09-17 15:30 – Updated: 2025-09-17 18:31

Details

Apache::AuthAny::Cookie v0.201 or earlier for Perl generates session ids insecurely.

Session ids are generated using an MD5 hash of the epoch time and a call to the built-in rand function. 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.

Severity

7.5 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
