perl-catalyst/Catalyst-Plugin-Session

Catalyst::Plugin::Session before version 0.44 for Perl generates session ids insecurely. The session id is generated from a (usually SHA-1) hash of a simple counter, the epoch time, the built-in rand function, the PID and the current Catalyst context. This information is of low entropy. 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.

A vulnerability has been found in Catalyst-Plugin-Session up to 0.40 and classified as problematic. This vulnerability affects the function _load_sessionid of the file lib/Catalyst/Plugin/Session.pm of the component Session ID Handler. The manipulation of the argument sid leads to cross site scripting. The attack can be initiated remotely. Upgrading to version 0.41 is able to address this issue. The name of the patch is 88d1b599e1163761c9bd53bec53ba078f13e09d4. It is recommended to upgrade the affected component. VDB-216958 is the identifier assigned to this vulnerability.
