CVE-2025-10964Public exploitNetwork attack vector

Authenticated command execution via unsanitized firewall parameter

Published Sep 25, 2025 · Updated Sep 25, 2025

Command injection in Wavlink WL-NU516U1 firmware M16U1_V240425 allows remote authenticated users to execute operating-system commands. The firewall.cgi sub_401B30 function copies the remoteManagementEnabled POST value through sprintf into a command passed to system without neutralization. An authenticated management session is required, and the published proof demonstrates execution by redirecting directory output to a file.
