VAR-202003-0264
Vulnerability from variot - Updated: 2023-12-18 13:56This 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. The issue results from the lack of proper validation of DNS reponses prior to further processing. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the root user. Was ZDI-CAN-9661. TP-Link Archer A7 AC1750 There is an input verification vulnerability in the firmware. Zero Day Initiative To this vulnerability ZDI-CAN-9661 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. The vulnerability stems from the program's failure to properly verify the DNS response before further processing
