Apache::Session Deleted Session Recreation Flaw

Apache::Session versions through 1.94 contain a critical flaw where the File and DB_File session stores inadvertently recreate sessions that were explicitly deleted. When a session is removed, the vulnerable code paths fail to properly prevent resurrection of that session data, allowing deleted sessions to be revived with their original—or potentially attacker-controlled—data intact. This affects any Perl-based web application using Apache::Session for session management, including those built on platforms like mod_perl. The vulnerability is particularly dangerous because session deletion is typically relied upon for security-critical operations like logout, password changes, and access revocation. An attacker could exploit this by inducing session resurrection to bypass logout mechanisms, maintain unauthorized access, or recover sensitive session state that administrators believed was securely removed.

Casky.ai's security skills mapping to MITRE ATT&CK would help practitioners detect attack patterns associated with session manipulation and persistence. While CVE-2013-10075 itself does not directly map to specific ATT&CK techniques in the initial assessment, practitioners using Casky's extended reasoning capabilities would identify suspicious patterns indicative of T1548 (Abuse Elevation Control Mechanism) or T1078 (Valid Accounts) exploitation—specifically, detection of session resurrection attempts, unexpected session recreation after deletion events, and authentication bypass scenarios where deleted sessions regain access. A practitioner reviewing Casky findings would observe anomalies such as session identifiers reappearing in logs after documented deletion, session data persisting beyond expected expiration windows, and authentication state inconsistencies that suggest sessions are being improperly revived rather than cleanly terminated.
