An authenticated OS command injection vulnerability has been identified in the WAVLINK WN553X1-B router, specifically in the V260403_2.0.0 firmware. The issue arises in the ioos service component, where user-controlled parameters 'group_id' and 'group_name' are improperly validated before being passed to the 'system' function. This flaw allows remote execution of arbitrary commands with root privileges on the device. Exploitation requires authentication and a valid session token, which can be obtained through the 'opt=login' endpoint.
