Technical details

A stack-based buffer overflow vulnerability exists in the UTT HiPER 2610G router firmware up to version 3.0.0-171107. The flaw is located in the '/goform/formConfigDnsFilterGlobal' endpoint due to the unsafe use of the 'strcpy' function when processing the 'GroupName' parameter. A remote attacker with low-level privileges can provide an overly long string to this parameter to overwrite memory. This can result in a denial-of-service (DoS) or arbitrary code execution. The exploit has been publicly disclosed.
