CVE-2025-10641 is a high-severity cleartext transmission of sensitive information vulnerability in WorkExaminer Professional from EfficientLab, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected WorkExaminer Professional versions: <= 4.0.0.52001. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.32% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
All WorkExaminer Professional traffic between monitoring client, console and server is transmitted as plain text. This allows an attacker with access to the network to read the transmitted sensitive data. An attacker can also freely modify the data on the wire. The monitoring clients transmit their data to the server using the unencrypted FTP. Clients connect to the FTP server on port 12304 and transmit the data unencrypted. In addition, all traffic between the console client and the server at port 12306 is unencrypted.

The underlying weakness: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How developers prevent this class of flaw
- Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
