Technical details

A stack-based buffer overflow exists in the UTT HiPER 1250GW router firmware up to version 3.2.7-210907-180535. The vulnerability is located within the Web Endpoint component, specifically in the '/goform/ConfigWirelessBase_5g' file. The root cause is the unsafe use of the 'strcpy' function when processing the 'ssid' (or 'Profile') parameter without adequate boundary checks. A remote attacker with low-level authentication can exploit this by sending a POST request with an oversized SSID string, leading to memory corruption. This can result in a denial of service (system crash) or potentially arbitrary code execution. A public exploit (PoC) has been disclosed.
