Archer A7
This vulnerability allows remote attackers to execute arbitrary code on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers
- Affected firmware
- Firmware Ver: 190726
- Fix
- Fix details in the linked record
Details and sources
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.

Details and sources
This vulnerability allows network-adjacent 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 tdpServer service, which listens on UDP port 20002 by default. When parsing the slave_mac parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the root user. Was ZDI-CAN-9650.
Archer A7
This vulnerability allows a firewall bypass on affected installations of TP-Link Archer A7 prior to Archer C7(US)_V5_210125 and Archer A7(US)_V5_200220 AC1750 routers

Details and sources
This vulnerability allows a firewall bypass on affected installations of TP-Link Archer A7 prior to Archer C7(US)_V5_210125 and Archer A7(US)_V5_200220 AC1750 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of IPv6 connections. The issue results from the lack of proper filtering of IPv6 SSH connections. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-12309.
