Epolicy Orchestrator Cross-site Scripting

A reflected cross-site scripting (XSS) vulnerability in ePO prior to 5.10 Update 14 allows a remote unauthenticated attacker to potentially obtain access to an ePO administrator's session by convincing the authenticated ePO administrator to click on a carefully crafted link. This would lead to limited access to sensitive information and limited ability to alter some information in ePO. (2022-10-18, CVE-2022-3339)

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. (2022-03-23, CVE-2022-0858)

Reflected Cross-Site Scripting vulnerability in McAfee ePolicy Orchestrator (ePO) 5.3.2, 5.3.1, 5.3.0 and 5.9.0 allows remote authenticated users to exploit an XSS issue via not sanitizing the user input. (2018-04-02, CVE-2018-6659)

Cross site scripting is an attack where a web page executes code that is injected by an adversary. It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.

The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:

https://server.com/confirmation?message=Transaction+Complete

what results in:

<span>Confirmation: Transaction Complete</span>

In that case the message can be modified to become a valid Javascript code, e.g.:

https://server.com/confirmation?message=<script>dangerous javascript code here</script>

and it will be executed locally by the user's browser with full access to the user's personal application/browser data:

<span>Confirmation: <script>dangerous javascript code here</script></span>
