Technical details
A stack-based buffer overflow exists in the UTT nv518G router within the 'gohead/sub_447CAC' component. The vulnerability is triggered when the application handles 'oldName' and 'newName' parameters via the '/formLinkageConfReName' endpoint. The software uses 'strcat' to append user-controlled strings to a fixed-size stack buffer that already contains a long USB path string. If the 'oldName' or 'newName' parameters exceed approximately 40 bytes, the buffer overflows, corrupting adjacent stack memory and the return address. A remote, unauthenticated attacker can exploit this to cause a denial of service (DoS) by crashing the device.
