disruption or full compromise.

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly prevents command injection by requiring validation of all inputs to the admin interface, blocking crafted inputs from reaching system command execution.

prevent

Mandates timely flaw remediation through firmware updates, eliminating the specific command injection vulnerability as recommended by TP-Link.

prevent

Enforces least privilege on authenticated admin accounts, limiting the scope and impact of any successfully injected system commands.

Security SummaryAI

CVE-2025-14756 is a command injection vulnerability (CWE-77) discovered in the admin interface component of TP-Link Archer MR600 v5 firmware. Published on 2026-01-26, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The flaw enables authenticated attackers to execute system commands via crafted input in the browser developer console, though with a limited character length.

An attacker with low-privilege authenticated access (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and without requiring user interaction (UI:N). Exploitation allows injection and execution of system commands, potentially resulting in service disruption or full compromise of the affected device.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
Why these techniques?

The vulnerability is a command injection (CWE-77) in a public-facing web admin interface (AV:N), enabling remote exploitation (T1190) to execute arbitrary system (Unix shell) commands (T1059.004).
