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 by generating insecure, predictable session IDs. The session IDs are created using a SHA-1 hash seeded with the built-in rand function, epoch time, and process ID (PID). Because the PID is from a small set and the epoch time can be guessed or leaked, the session IDs are predictable. This vulnerability could allow attackers to guess session IDs and potentially gain unauthorized access. The Ado::Sessions project is no longer maintained and has been removed from the CPAN index, though it remains available on BackPAN. No official patch or remediation is currently available.
AI Analysis
Technical Summary
Ado::Sessions versions through 0.935 generate session IDs by hashing a combination of the built-in rand function output, the epoch time, and the process ID using SHA-1. The built-in rand function is not cryptographically secure, and the PID and epoch time values are predictable or guessable, resulting in predictable session IDs. This weakness falls under CWE-340 (Generation of Predictable Numbers or Identifiers) and CWE-338 (Use of Cryptographically Weak Pseudo-Random Number Generator). Because session IDs are predictable, attackers could potentially guess valid session tokens and gain unauthorized access to sessions. The project is unmaintained and no fixes have been published.
Potential Impact
The vulnerability allows attackers to predict session IDs due to weak randomness in their generation. This could lead to unauthorized session hijacking or access to user sessions. However, no known exploits are reported in the wild. The impact is limited to confidentiality and integrity of sessions managed by Ado::Sessions in affected versions.
Mitigation Recommendations
No official patch or remediation is currently available as the Ado::Sessions project is no longer maintained. Users are advised to discontinue use of Ado::Sessions and migrate to a maintained session management library that uses cryptographically secure random number generation for session IDs. Patch status is not yet confirmed — check vendor advisories or community sources for any updates.
