CVE-2025-8181 Details
Description
A vulnerability, which was classified as critical, was found in TOTOLINK N600R and X2000R 1.0.0.1. This affects an unknown part of the file vsftpd.conf of the component FTP Service. The manipulation leads to least privilege violation. It is possible to initiate the attack remotely.
A critical misconfiguration vulnerability has been identified in TOTOLINK N600R and X2000R devices running version 1.0.0.1. The issue arises in the FTP service configuration file vsftpd.conf, where the chown_uploads property is enabled but the necessary chown_username property is not explicitly set, defaulting to root. This flaw allows remote attackers with anonymous FTP access to upload files that are automatically owned by the root user, potentially leading to unauthorized root-level control over the device.
