Overview

CVE-2025-10640 is a critical-severity vulnerability. It was published on October 21, 2025 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

An unauthenticated attacker with access to TCP port 12306 of the WorkExaminer server can exploit missing server-side authentication checks to bypass the login prompt in the WorkExaminer Professional console to gain administrative access to the WorkExaminer server and therefore all sensitive monitoring data. This includes monitored screenshots and keystrokes of all users.

The WorkExaminer Professional console is used for administrative access to the server. Before access to the console is granted administrators must login. Internally, a custom protocol is used to call a respective stored procedure on the MSSQL database. The return value of the call is not validated on the server-side. Instead it is only validated client-side which allows to bypass authentication.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
