Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Requires validation of untrusted inputs like the restart_hour_value POST parameter to directly prevent OS command injection in login.cgi set_sys_init().
Mandates identification, reporting, and correction of flaws such as this command injection vulnerability through timely patching of the affected firmware.
Enforces boundary protection to monitor and control HTTP traffic, blocking specially crafted unauthenticated requests exploiting the vulnerable endpoint.
NVD Description
Multiple OS command injection vulnerabilities exist in the login.cgi set_sys_init() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary code execution. An attacker can make an unauthenticated HTTP request to trigger these vulnerabilities.A command injection…
