The attack may be performed from remote. There is no available exploit. Detailsinfo A vulnerability was found in BEROV Ado::Sessions up to 0.935 on Perl and classified as problematic. Affected by this issue is the function rand. The manipulation with an unknown input leads to a generation of predictable numbers or identifiers vulnerability. Using CWE to declare the problem leads to CWE-340. The product uses a scheme that generates numbers or identifiers that are more predictable than required. Impacted is integrity. CVE summarizes: Ado::Sessions versions through 0.935 for Perl generates insecure session ids. The session id is generated from a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. 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. Note that Ado is no longer maintained, and has been removed from the CPAN index. It is still available on BackPAN.
