Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of DNS responses. A crafted DNS message can trigger an overflow of a fixed-length, stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the root user. Was ZDI-CAN-9660. TP-Link Archer A7 AC1750 There is an out-of-bounds write vulnerability in the firmware. Zero Day Initiative To this vulnerability ZDI-CAN-9660 Was numbered.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. TP-Link Archer A7 AC1750 is a wireless router of China TP-Link company
