CVE-2026-9044: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in TP-Link Systems Inc. AXE75 V1
An OS command injection vulnerability exists in the VPN module of TP-Link AXE75 V1 routers. This vulnerability allows an adjacent, authenticated attacker to execute arbitrary commands on the device by importing a specially crafted VPN client configuration file. The issue arises from improper filtering of special characters. Successful exploitation of this vulnerability may enable an attacker to gain full control of the affected device, potentially compromising configuration integrity, network security, and service availability.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-9044) affects the VPN module of TP-Link AXE75 V1 routers. It is caused by improper neutralization of special elements used in OS commands (CWE-78), allowing an adjacent attacker with authentication to execute arbitrary OS commands by importing a malicious VPN client configuration file. The root cause is insufficient filtering of special characters in the input. Successful exploitation can lead to complete compromise of the device.
Potential Impact
An attacker who is adjacent on the network and authenticated to the device can execute arbitrary OS commands, potentially gaining full control of the router. This can compromise device configuration, network security, and availability of services provided by the device.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time. Until a patch is available, restrict access to the VPN configuration import functionality to trusted users only and monitor for suspicious activity related to VPN configuration imports.
