CVE-2022-3339Network attack vector

Administrator session access via reflected script injection

Published Oct 18, 2022 · Updated May 8, 2025

Reflected XSS in Trellix ePolicy Orchestrator before 5.10 Update 14 allows remote attackers to access an administrator session. Trellix has not disclosed the affected request parameter or the server-side reflection point that places attacker-controlled input into an ePO response. Exploitation requires an authenticated ePO administrator to open a crafted link, enabling limited access to sensitive information and limited alteration through that session.
