Technical details

A stack-based buffer overflow vulnerability exists in the UTT HiPER 1200GW router firmware up to version 2.5.3-170306. The flaw is located within the '/goform/setSysAdm' endpoint of the Web Management Interface, specifically due to the unsafe use of the 'strcpy' function when processing the 'sysAdmUser' or 'sysAdmPass' (identified as 'passwd1' in technical proofs) parameters. A remote attacker with low-level authentication can send a specially crafted POST request containing an excessively long string to trigger the overflow. This can result in a denial of service (system crash) or potentially remote code execution. Public exploit code has been released.
