CVE-2025-9579Public exploitNetwork attack vector

Authenticated command execution via unneutralized enable parameter

Published Aug 28, 2025 · Updated Aug 28, 2025

OS command injection in the HTTP handler in LB-LINK BL-X26 1.2.8 allows remote authenticated users to execute commands via an HTTP POST. The set_hidessid_cfg route passes the enable form value through bs_SetSSIDHide, which concatenates it into a shell command without neutralization. A valid management session and type=sethide2 are required; successful exploitation runs commands with the router service's privileges.
