A buffer overflow vulnerability has been identified in the UTT HiPER 1250GW router, affecting firmware versions through 3.2.7-210907-180535. The issue arises in the Parameter Handler component, specifically within the formConfigDnsFilterGlobal API. The vulnerability is triggered by manipulating the GroupName parameter, which is then copied to a buffer using the strcpy function without proper size validation. This oversight creates a buffer overflow condition that can be exploited remotely, potentially leading to a denial-of-service situation.
