Vulnerability description
A persistent denial-of-service vulnerability in Endpoint Security (HX) Server 10.0.2 and earlier may cause the incorrect processing of exceptions, which in turn would prevent additional events from functioning correctly, resulting in disruption of service.
CVE-2025-0618
A malicious third-party can invoke a persistent denial-of-service vulnerability in Endpoint Security (HX) by sending a specially-crafted tamper protection event to the HX service to trigger an exception.
This exception prevents any further tamper protection events from being processed, even after a reboot of HX.

What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council's effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, visit the CVSS website.When calculating CVSS scores, we have adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by the successful exploitation of the issue being scored.
What are the CVSS scoring metrics?

Where can I find a list of all Security Bulletins?
All Security Bulletins are published in our Security Centre. Security Bulletins are retired (removed) once a product is both End of Sale and End of Support (End of Life).How do I report a product vulnerability to Trellix or Skyhigh Security?
If you have information about a security issue or vulnerability with a Trellix or Skyhigh Security product, visit the PSIRT website for instructions at Report a vulnerability.How does Trellix or Skyhigh Security respond to this and any other reported security flaws?
Our key priority is the security of our customers. If a vulnerability is found within any of our software or services, we work closely with the relevant security software development team to ensure the rapid and effective development of a fix and communication plan.We only publish Security Bulletins if they include something actionable such as a workaround, mitigation, version update, or hotfix. Otherwise, we would simply be informing the hacker community that our products are a target, putting our customers at greater risk. For products that are updated automatically, a non-actionable Security Bulletin might be published to acknowledge the discoverer.
