CVE-2019-3591: McAfee Data Loss Prevention Endpoint

Medium severity, CVSS 6.1. EPSS: 0.8% chance of exploitation in the next 30 days.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ePO extension in McAfee Data Loss Prevention (DLPe) for Windows 11.x prior to 11.3.0 allows unauthenticated remote user to trigger specially crafted JavaScript to render in the ePO UI via a carefully crafted upload to a remote website which is correctly blocked by DLPe Web Protection. This would then render as an XSS when the DLP Admin viewed the event in the ePO UI.

Affected products

• McAfee Data Loss Prevention Endpoint: from 11.0, before 11.1.200 (fixed in 11.1.200); from 11.2.000, before 11.3.0 (fixed in 11.3.0)
