CVE-2020-10882: This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of...

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.

Security readout for executives and security teams

An attacker on the same or adjacent network could take over an affected TP-Link Archer A7 router without logging in. The flaw can allow code execution as root, so compromise could affect confidentiality, integrity, and availability of traffic and router operations. Exposure is limited by the source description to network-adjacent attackers. Organizations are most likely exposed where TP-Link Archer A7 routers running Firmware Ver: 190726 are reachable from local, guest, IoT, or other adjacent network segments. Treat this as a high-priority edge-network exposure if affected routers exist. The issue needs prompt inventory, vendor-fix review, and local network access reduction because compromise could hand an attacker root control of the router. Mitigation focus: Inventory TP-Link Archer A7 routers and identify Firmware Ver: 190726.; Check TP-Link guidance for fixed firmware or replacement recommendations.; Update affected routers if vendor-supported firmware is available..
