Technical details

This vulnerability is classified as Improper Input Validation (CWE-20) within the management interface of NETGEAR Nighthawk RAX series routers. An attacker with high privileges (PR:H) and access to the adjacent network (AV:A) can exploit this flaw to achieve remote code execution or unauthorized command execution. The root cause is a failure to properly validate input before processing, which can be leveraged by an authenticated user to compromise the integrity of the system. Patches have been released in firmware versions V1.0.17.142 and V1.1.6.36 depending on the specific model.
