CVE-2025-40931 (2026-03-05)

Apache::Session::Generate::MD5 versions through 1.94 for Perl create insecure session id. Apache::Session::Generate::MD5 generates session ids insecurely. The default session id generator 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.

NAME

Apache::Session::Serialize::Storable - Use Storable to zip up persistent data

SYNOPSIS

use Apache::Session::Serialize::Storable;

$zipped = Apache::Session::Serialize::Storable::serialize($ref);
$ref = Apache::Session::Serialize::Storable::unserialize($zipped);

DESCRIPTION

This module fulfills the serialization interface of Apache::Session. It serializes the data in the session object by use of Storable's nfreeze() and thaw() functions. The result is a binary object ready for storage.
