An OS\ncommand injection vulnerability exists in the VPN module of TP-Link Archer AX12\nv1, AX17 v1. AX18 v1, and AX1300 v1.6 routers. This vulnerability allows an\nadjacent, authenticated attacker to execute arbitrary commands on the device by\nimporting a specially crafted VPN client configuration file. The issue stems\nfrom improper filtering of special characters.
\n\nSuccessful\nexploitation of this vulnerability may enable an attacker to gain full control\nof the affected device, potentially compromising configuration integrity,\nnetwork security, and service availability.
