Authenticated Command Injection in TP-Link Archer MR600 v5 (CVE-2025-14756)
TP-Link issued a security advisory for an authenticated command injection vulnerability in the Archer MR600 v5 router’s web-based admin interface, tracked as CVE-2025-14756 with a CVSS 8.5 rating. The flaw stems from insufficient input sanitization in the admin interface component, enabling a logged-in attacker to execute arbitrary system commands by submitting crafted input via the browser’s developer console; while the injected command length is limited, successful exploitation can still result in service disruption or full device compromise.
Affected devices are Archer MR600 v5 units running firmware versions prior to the fixed release (reported as versions below v0001.0 Build 250930 Rel.63611n / older than 1.1.0 and including 0.9.1 and below, depending on versioning notation in the advisory). The reported attack conditions include requiring valid admin credentials and adjacent network access, but the impact is high due to potential complete router takeover; TP-Link’s recommended mitigation is to apply the latest firmware update immediately, and one report notes the model is not sold in the United States, potentially limiting exposure there.
