siemens reyrolle

Siemens Reyrolle coverage on WindowsForum centers on security advisories for 7SR5 protection relays used in substation and industrial environments. The tagged content documents a Siemens ProductCERT advisory, SSA-142885, republished by CISA, covering 14 vulnerabilities in 7SR5 firmware releases earlier than V2.70, including an authentication-bypass flaw rated 9.8 under CVSS v3.1 that could let an unauthenticated attacker derive valid web-interface session identifiers. Because the advisory applies to every identified 7SR5 release below V2.70, the practical takeaway for operators is to treat affected relays as a priority patching case and move to V2.70 or later.
