Name of the Vulnerable Software and Affected Versions Logpoint SIEM versions 6.10.0 through 7.x before 7.3.0

Description The Jinja templating in Logpoint SIEM does not correctly sanitize log data being displayed when using a custom Jinja template in the Alert view. A remote attacker can craft a cross-site scripting (XSS) payload and send it to any system or device that sends logs to the SIEM. If an alert is created, the payload will execute upon the alert data being viewed with that template, which can lead to sensitive data disclosure.

Recommendations For versions 6.10.0 through 7.x before 7.3.0, update to version 7.3.0 or later to resolve the issue. As a temporary workaround, consider disabling the use of custom Jinja templates in the Alert view until a patch is available. Restrict access to the Alert view to minimize the risk of exploitation. Avoid using custom Jinja templates that can lead to log data injection until the issue is resolved.
