CVE-2026-5083: CWE-340 Generation of Predictable Numbers or Identifiers in BEROV Ado::Sessions
CVE-2026-5083 affects Ado::Sessions versions through 0. 935 for Perl, where session IDs are generated using a SHA-1 hash seeded with insecure sources including the built-in rand function, epoch time, and process ID. The use of predictable inputs results in session IDs that can be guessed or predicted by attackers. This vulnerability could allow unauthorized access to systems relying on these session IDs for authentication. The Ado::Sessions project is no longer maintained and has been removed from the CPAN index, with no official patch or remediation available.
AI Analysis
Technical Summary
Ado::Sessions versions up to 0.935 generate session identifiers using a SHA-1 hash seeded by the built-in Perl rand function, epoch time, and process ID (PID). The PID is drawn from a limited range, and the epoch time may be inferred from HTTP headers, making the session IDs predictable. The built-in rand function is not cryptographically secure, leading to weak session ID generation. This predictable session ID generation (CWE-340, CWE-338) can allow attackers to guess valid session IDs and potentially gain unauthorized access. The project is unmaintained and removed from CPAN, with no available patches.
Potential Impact
The vulnerability allows attackers to predict session IDs due to weak randomness in their generation. This can lead to unauthorized access to user sessions or systems relying on these session IDs for authentication. No known exploits are reported in the wild. Since the project is unmaintained and no patches exist, affected systems remain vulnerable if still in use.
Mitigation Recommendations
No official fix or patch is available as the Ado::Sessions project is no longer maintained and has been removed from CPAN. Users should discontinue use of Ado::Sessions and migrate to maintained session management libraries that use cryptographically secure random number generators for session ID creation. Patch status is not yet confirmed — check vendor advisories or community resources for any unofficial mitigations.
