Unauthenticated code execution via HTTP header parsing
Published Mar 20, 2024 · Updated Oct 28, 2024
Memory corruption in Elspec G5 digital fault recorder 1.1.4.15 and earlier allows remote attackers to execute code through HTTP headers. The HTTP header parser corrupts memory while processing attacker-controlled header data; Elspec has not disclosed the malformed-header condition or affected routine. No authentication or user interaction is required, and successful exploitation can compromise the recorder's confidentiality, integrity, and availability.
