Official Description
A reflected cross-site scripting (XSS) vulnerability in McAfee Enterprise ePolicy Orchestrator (ePO) prior to 5.10 Update 13 allows a remote attacker to potentially obtain access to an ePO administrator's session by convincing the attacker to click on a carefully crafted link.

Technical Analysis
CVE-2022-0857 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
