Archer MR600 v5.0: Improper Neutralization of Special Elements used in a Command

Published Updated By the CyberSecBulletin desk

CVE-2025-14756 is a high-severity improper neutralization of special elements used in a command vulnerability in Archer MR600 v5.0 from TP-Link, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 1.1.0 0.9.1 v0001.0 Build 250930 Rel.63611n as the first without the flaw, so updating Archer MR600 v5.0 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.77% chance of exploitation within 30 days, higher than 87% of scored CVEs.

Official description

Command injection vulnerability was found in the admin interface component of TP-Link Archer MR600 v5 firmware, allowing authenticated attackers to execute system commands with a limited character length via crafted input in the browser developer console, possibly leading to service disruption or full compromise.

The underlying weakness: Improper Neutralization of Special Elements used in a Command

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
