Overview

Multiple vulnerabilities have been reported in TP-Link Archer NX200, NX210, NX500, and NX600 routers which could allow the attacker to perform unauthorized privileged HTTP actions, potentially leading to arbitrary modification or tampering of the device¿s configuration data.

Target Audience:
All organizations and individuals using TP-Link Archer router.

Risk Assessment:
High risks of service interruption and unauthorized access.

Impact Assessment:
Potential impact on confidentiality, integrity and availability of the system.

Description

1. Authorization Bypass Vulnerability ( CVE-2025-15517   )

A vulnerability exists in the TP-Link Archer NX200, NX210, NX500, and NX600 routers due to a missing authentication check in the HTTP server for certain CGI endpoints. This vulnerability could exploit by unauthenticated us-ers to access functionality intended only for authenticated users.
Successful exploitation of this vulnerability could enable an attacker to per-form privileged HTTP actions without authentication, including firmware up-loads and configuration changes.

2. Command Injection Vulnerability ( CVE-2025-15518   CVE-2025-15519   )

Multiple vulnerabilities exist in the TP-Link Archer NX200, NX210, NX500, and NX600 routers due to improper input handling in the wireless-control modem-management administrative CLI command.
Successful exploitation of these vulnerabilities could allow an authenticated attacker with administrative privileges to execute arbitrary commands on the underlying operating system of the targeted device.

3. Privilege Escalation Vulnerability ( CVE-2025-15605   )

A hardcoded cryptographic key within the configuration mechanism of the TP-Link Archer NX200, NX210, NX500, and NX600 routers allows for the de-cryption and re-encryption of device configuration data. An authenticated at-tacker with administrative privileges could exploit this vulnerability to decrypt configuration files, modify them, and re-encrypt them, thereby compromising the confidentiality and integrity of the device¿s configuration.
Successful exploitation of this vulnerability could allow an attacker to tamper with configuration data on the targeted system.
