Urgent Tech Update – Vulnerability on McAfee ENS that could allow a malware to delete files

McAfee has detected a vulnerability on ENS that could allow a malware or malicious user to delete files that he should not have any access to. McAfee has already created expert rules and a DAT update should be published today to reduce the risk. Patches are not available yet.

This vulnerability does not provide the ability to remotely exploit a system, but rather enables malware or a malicious actor to delete files that they otherwise would not have access to. Exploitation of the vulnerability requires running code (or a script) on a victim system that maliciously manipulates symbolic links to redirect a delete action of a privileged process to an unintended file.


Product Vulnerability Status

Investigation into McAfee products is ongoing. This Security Bulletin will be updated as additional information is available.

Product Version Notes

Vulnerable and Update Planned

Endpoint Security (ENS) for Mac All  N/A
ENS for Windows 10.7.x
VirusScan Enterprise (VSE) for Linux All  N/A
VSE for Windows All  N/A


Investigation of impacted McAfee products is ongoing. McAfee’s Security Bulletin will be updated as additional information is available.



ENS for Windows (10.7.x, 10.6.x, 10.5.x)
An interim mitigation is available through an Expert Rule (KB92752). You can deploy the mitigation in your environment to provide protection against attempted exploit of this vulnerability. Due to the aggressive nature of this rule, McAfee recommends the standard best practice of testing the rule as “report only” in your environment to rule out unintended behavior.

A v3 DAT release that prevents exploitation of this vulnerability in ENS 10.5, 10.6 and 10.7 is planned for release on April 24, 2020 (Today). This update will address the issue for the products listed above.
