Description
The affected TP-Link Aginet devices contain a flaw in the web management interface where authentication
checks are not consistently enforced on certain endpoints. An attacker can send
specially crafted requests to bypass authentication and directly invoke
privileged functionality without valid credentials. This issue arises from
improper enforcement of access control mechanisms on sensitive operations.





Successful
exploitation may allow an unauthenticated attacker to execute privileged
operations and gain full control of the device.

Impact

The flaw allows an attacker to bypass authentication checks on certain web interface endpoints and invoke privileged operations without valid credentials, giving full control of the device. The vulnerability arises from improper enforcement of access control mechanisms on sensitive operations, which can lead to compromise of confidentiality, integrity, and availability.

Affected Systems

The vulnerability affects a wide range of TP‑Link Aginet devices. Specific models include EX141 (BR/EU1/US1) v1.0–v1.9, EX220 (BR/EU1) v1.0–v1.20/1.28/1.29/1.8/2.0, EX222 (EU1/KR/US1) v1.0, EX511 (BR/EU1/US1) v2.0–v2.9, EX520 (US1) v1.0, EX521 (US1) v1.0, EX820v (EU1) v1.0, EX920 (US2) v1.0–v1.6, HB210 (EU1/US2) v1.0–v1.6, HB410 (EU1) v1.0, HB610 (CA/EU1/US2) v2.0–v2.6, HB710 (EU1/US2) v1.0–v1.6, HB810 (EU1/US2) v1.0–v2.6, HC220‑G5 (BR/EU1/US1) v1.0–v1.30, HX141 (EU1) v1.0, HX220 (AU/CA/EU1/US1) v1.0, HX510 (AU/CA/EU1/US1/US2) v1.0–v2.6, HX710 (EU1) v1.0, VX1800v (EU1) v1.0, VX420‑G2h (AU) v3.0, VX800v (DE) v1.0, XC220‑G3v (EU1/US1) v2.30, XX230v (BR) v1.0, XX530v (BR/US1/EU1) v1.0–v2.0.

Risk and Exploitability

The CVSS score of 8.7 indicates a high severity vulnerability that can lead to full device compromise. Because the attack vector is remote through the web management interface and no authentication is required, the EPSS score is not available but the absence of a KEV listing suggests that public exploitation may not yet be widespread; however, the risk remains high. The flaw directly bypasses authorization controls (CWE‑862), allowing unauthenticated users to invoke privileged operations that affect confidentiality, integrity, and availability of the device.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the device firmware to the latest version that resolves the broken access control flaw (check the TP‑Link support site for available firmware releases).
  • Disable or restrict external access to the web management interface, for example by limiting management traffic to a trusted internal subnet or whitelisting specific IP addresses.
  • Implement network segmentation so that administrative traffic to the devices is isolated from general user traffic and protected by a dedicated firewall.
  • Continuously monitor device logs for unusual management activity and enforce strong administrative passwords on each device.
