Authenticated code execution via unchecked GroupName copy
Published Jun 8, 2026 · Updated Jun 8, 2026
Buffer overflow in UTT HiPER 2610G 3.0.0-171107 allows remote authenticated users to execute code via a crafted DNS-filter request. The formConfigDnsFilterGlobal handler copies the attacker-controlled GroupName value with strcpy to InstPointByIndex + 180 without checking its length. An authenticated management session reaches the HTTP POST path, where the overflow can crash the gateway or execute code in its firmware context.
