Vulnerability from variot

Asus RT-AC68U <3.0.0.4.385.20633 and RT-AC5300 <3.0.0.4.384.82072 are affected by a buffer overflow in blocking_request.cgi. ASUSTeK Computer Inc. of RT-AC68U firmware and RT-AC5300 Firmware has a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. ASUS RT-AC68U and ASUS RT-AC5300 are both routers from the Chinese company ASUS (ASUS).

Asus RT-AC68U versions prior to 3.0.0.4.385.20633 and RT-AC5300 versions prior to 3.0.0.4.384.82072 have a command injection vulnerability. The vulnerability stems from the fact that when performing operations on memory in blocking_request.cgi, the data boundary is not properly verified. Exploiting this vulnerability leads to arbitrary command execution
