TP-Link Unauthenticated CGI Cross-Site Request Forgery (Remote)

critical Nessus Plugin ID 117861
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host is affected by multiple vulnerabilities.


The TP-Link web interface on the remote host is vulnerable to a cross-site request forgery and an authentication bypass vulnerability. An unauthenticated attacker could leverage these vulnerabilities to bypass authentication and potentially gain administrative access to the affected host.


Contact the device vendor for updated firmware. Additionally, access control may be implemented to mitigate these vulnerabilities.
