CVE-2023-4291Network attack vector

Unauthenticated code execution via manipulated web parameters

Published Sep 21, 2023 · Updated Sep 24, 2024

Code injection in Frauscher Diagnostic System FDS101 1.4.24 and earlier allows remote attackers to execute code via web parameters. The web interface incorporates manipulated request parameters into generated code without adequately controlling their syntax; the affected endpoint or function is undisclosed. No authentication or user interaction is required, and successful exploitation permits full compromise of the diagnostic appliance.
