A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). (CVE-2026-62647)
A vulnerability in Reyrolle 7SR5 versions prior to 2.70 involves the use of a non-true random number generator for security-relevant values such as session identifiers. This flaw allows an unauthenticated remote attacker to predict these values and potentially impersonate legitimate users, gaining unauthorized access. The vulnerability has a CVSS score of 7.4, indicating high severity. No patch or remediation information is currently provided.
AI Analysis
Technical Summary
Reyrolle 7SR5 versions before 2.70 use a random number generator for security-critical values that is not seeded with a True Random Number Generator (TRNG). This results in predictable sequences of generated values like session identifiers used for authentication. An unauthenticated remote attacker could exploit this predictability to impersonate legitimate users and gain unauthorized access to the device. The vulnerability is identified as CVE-2026-62647 with a CVSS 3.1 base score of 7.4 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N).
Potential Impact
The vulnerability allows an unauthenticated remote attacker to predict security-relevant values such as session identifiers, potentially enabling unauthorized access to the affected Reyrolle 7SR5 devices. This compromises confidentiality and integrity but does not impact availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is provided at this time.
