CVE-2025-6559Network attack vector

Unauthenticated command execution via OS command injection

Published Jun 24, 2025 · Updated Jun 24, 2025

OS command injection in twelve Sapido wireless router models at version 0 allows remote attackers to execute arbitrary commands. TWCERT/CC identifies arbitrary OS-command injection on the router server but does not disclose the request parameter, endpoint, or command-construction locus. Network reachability to the affected interface and no authentication are required; successful exploitation grants command execution with confidentiality, integrity, and availability impact.
