| Title | Predictable Session Identifier Generation in Siemens Reyrolle 7SR5 Enables Authentication Impersonation |
Tue, 08 Sep 2026 08:30:00 +0000
| Type | Values Removed | Values Added |
|---|---|---|
| Description | A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). 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. 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. | |
