Detection Guidance

Detection of this vulnerability involves checking if the Axigen WebMail server is running a vulnerable version (10.3.x, 10.4.x, 10.5.x up to 10.5.56, or 10.6.x up to 10.6.25) and verifying if the timeFormat account preference parameter has been tampered with to include malicious JavaScript payloads.

Since exploitation requires modification of the timeFormat preference, inspecting user account preferences for suspicious or unexpected JavaScript code in the timeFormat parameter can help detect compromise.

No specific commands are provided in the available resources for detection.

Mitigation Strategies

The recommended immediate mitigation is to update Axigen WebMail to fixed versions 10.5.57 or later, or 10.6.26 or later.

Additionally, reviewing and securing user credentials to prevent unauthorized modification of the timeFormat preference is important.

Monitoring and restricting access to the WebMail interface to trusted users can also reduce risk.
