CWE
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Summary
An OS Command Injection vulnerability exists in the Surfshark VPN login functionality in TP-Link Archer BE230 v1.2, BE3600v1, AX10 v3 and AXE75 v1, allowing an adjacent
authenticated
attacker to execute arbitrary code. Successful exploitation could allow an attacker to gain full administrative control of the device, resulting in severe compromise of configuration integrity, network security, and service availability.
This CVE covers one of multiple distinct OS command injection issues identified across separate code paths. Although similar in nature, each instance is tracked under a unique CVE ID.
This issue affects Archer BE230 v1.2 < 1.2.4 Build 20251218 rel.70420 and Archer AXE75 v1 < 1.5.6 Build 20260623.
