Executive Summary

This vulnerability is a cross-site scripting (XSS) issue in Fortinet FortiSIEM versions 7.4.0 and 7.3.0 through 7.3.4. It occurs because the software improperly neutralizes input during web page generation, allowing a remote unauthenticated attacker to inject arbitrary data.

An attacker can exploit this by crafting spoofed URL parameters that trick users into executing malicious scripts, often through social engineering techniques.

Impact Analysis

This vulnerability can impact you by enabling attackers to perform social engineering attacks through spoofed URLs. If a user clicks on such a malicious link, it could lead to the execution of arbitrary scripts in the user's browser.

While the vulnerability does not directly compromise confidentiality or availability, it can lead to integrity issues by allowing attackers to manipulate the content displayed to users.
