Unauthenticated command execution via firewall CGI input

Published May 20, 2025 · Updated May 21, 2025

Command injection in /cgi-bin/firewall.cgi in Wavlink WL-WN579A3 1.0 allows remote attackers to execute arbitrary commands. The published record identifies a crafted input reaching firewall.cgi but does not disclose the parameter or command-building operation that fails to neutralize it. No authentication or user interaction is required, and successful exploitation compromises the repeater's confidentiality, integrity, and availability.
