A critical security advisory has been issued concerning a command injection vulnerability affecting the Archer MR600 v5 router. The flaw, designated as CVE-2025-14756, allows authenticated attackers to execute arbitrary system commands via the device's admin interface, potentially leading to a complete router takeover.
The vulnerability is present in the admin interface component of the Archer MR600 v5 firmware. Attacks require authentication credentials, enabling the injection of system commands through crafted input submitted via the browser developer console. Despite a character-length restriction on commands, attackers can execute malicious instructions to disrupt services or gain full control of the device.
CVE ID CVSS Score Affected Product Affected Versions
CVE-2025-14756 8.5 Archer MR600 v5 <1.1.0, 0.9.1, v0001.0 Build 250930 Rel.63611n
A critical security advisory has been issued concerning a command injection vulnerability affecting the Archer MR600 v5 router.
The vulnerability has been assigned a CVSS v4.0 score of 8.5, indicating a high-severity risk. The CVSS vector (CVSS:4.0/AV:A/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) suggests that the attack requires adjacent network access and high privilege levels, posing significant risks to the confidentiality, integrity, and availability of the router's functions.
This flaw specifically impacts the Archer MR600 v5 with firmware versions earlier than v0001.0 Build 250930 Rel.63611n (version 0.9.1 and below). TP-Link has not released this product in the United States, which limits its exposure there. However, users in other regions with affected devices face potential security risks.
TP-Link strongly advises users to download and install the latest firmware version immediately to address this vulnerability. The updated firmware resolves the command injection flaw, restoring security integrity. Users can access firmware updates through TP-Link's official support portal.
This vulnerability underscores the need to secure administrative interfaces on network devices. Authenticated command injection flaws can facilitate lateral movement within networks, especially in enterprise settings where routers serve as critical infrastructure components. Organizations managing TP-Link Archer devices should prioritize firmware updates and implement network segmentation to restrict administrative access. Additionally, monitoring for suspicious command execution patterns on affected routers can help detect exploitation attempts before damage occurs.
TP-Link emphasizes that failing to apply the recommended security updates leaves systems vulnerable to exploitation. The vendor cannot be held responsible for security incidents resulting from neglecting to implement these critical patches.
