CVE-2025-3361Network attack vector

Unauthenticated command execution via web service injection

Published Apr 8, 2025 · Updated Apr 8, 2025

OS command injection in HGiga iSherlock 4.5 and 5.5 before build 236 allows remote attackers to execute arbitrary server commands. TWCERT/CC identifies the web service as the vulnerable locus but does not disclose the affected request, parameter, or command-construction operation. No authentication or user interaction is required, and successful injection executes arbitrary commands on the iSherlock server.
