Technical details

A stack-based buffer overflow vulnerability exists in the UTT HiPER 1250GW router firmware up to version 3.2.7-210907-180535. The flaw is located within the /goform/formRemoteControl handler, specifically due to the unsafe use of 'strcpy' when processing the 'Profile' parameter. An authenticated remote attacker can provide a specially crafted, overly long string to this parameter to overwrite the stack. This can result in a denial of service (system crash) or potentially arbitrary code execution. A public exploit has been released, increasing the risk of active exploitation.
