CVE-2022-0858 | Cross-site scripting vulnerability in ePO

A 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. This would lead to limited ability to alter some information in ePO due to the area of the User Interface the vulnerability is present in.

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
4.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
