CVE-2026-62647
NVD: A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). NVD: A random number generator is used to generate security-relevant values (such as session identifiers used for authentication purposes) that is not initialized with a True Random Number Generator (TRNG), resulting in a predictable sequence of generated values. NVD: This could allow an unauthenticated remote attacker to more easily predict the generated values and impersonate a legitimate authenticated user, potentially gaining unauthorized access to the device.
