## Technical details

An OS command injection vulnerability exists within the VPN modules of the TP-Link Archer BE230 v1.2 and the OpenVPN component of the Archer AXE75 v1. The flaw is caused by improper neutralization of special elements used in OS commands (CWE-78) across specific code paths. An adjacent attacker with low-level authentication can exploit this to execute arbitrary system commands. Successful exploitation grants the attacker full administrative access to the device, compromising configuration integrity and service availability. Patches are available in firmware versions 1.2.4 Build 20251218 (BE230) and 1.5.6 Build 20260623 (AXE75).
