Predictable session ID generation in Apache::Session::Generate::ModUniqueId 1.54-1.94 allows remote unauthenticated attackers to forge session tokens and hijack user sessions. The vulnerability stems from using Apache mod_unique_id values as session identifiers-these values are deterministic and constructed from publicly observable or easily guessable components (server IP, process ID, timestamp, counter). With CVSS 9.1 and SSVC automation classification, this enables systematic session hijacking at scale despite no confirmed active exploitation.
Apache::Session versions through 1.94 for Perl re-creates deleted sessions. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
