CVE-2023-6452

/// Technical description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Forcepoint Web Security (Transaction Viewer) allows Stored XSS.

The

Forcepoint Web Security portal allows administrators to generate

detailed reports on user requests made through the Web proxy. It has

been determined that the "user agent" field in the Transaction Viewer is

vulnerable to a persistent Cross-Site Scripting (XSS) vulnerability,

which can be exploited by any user who can route traffic through the

Forcepoint Web proxy.

This

vulnerability enables unauthorized attackers to execute JavaScript

within the browser context of a Forcepoint administrator, thereby

allowing them to perform actions on the administrator's behalf. Such a

breach could lead to unauthorized access or modifications, posing a

significant security risk.

This issue affects Web Security: before 8.5.6.
