Authenticated command execution via unsanitized ipaddr concatenation
Published Sep 22, 2025 · Updated Sep 22, 2025
OS command injection in Wavlink WL-NU516U1 240425 allows remote authenticated users to execute commands through a crafted ipaddr value. After successful login verification, sub_4012A0 takes the ipaddr parameter and concatenates it into a string passed for system execution without command neutralization. Administrative credentials are required, and successful exploitation runs attacker-chosen commands on the embedded appliance.
