What it is

A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). A session identifier is generated using an algorithm with insufficient randomness, resulting in a token with low entropy that can be predicted or brute-forced within a feasible number of attempts. This could allow an unauthenticated remote attacker to derive valid session identifiers and bypass authentication.
