Name of the Vulnerable Software and Affected Versions: FortiAnalyzer versions 6.0.10 and below FortiAnalyzer versions 6.2.7 and below FortiAnalyzer versions 6.4.3 and below

Description: The issue is related to an improper neutralization of input, which may allow a remote authenticated attacker to perform a stored cross-site scripting attack via the column settings of Logview in FortiAnalyzer. This could happen if the attacker can obtain a specific POST request, potentially through other hypothetical attacks.

Recommendations: For FortiAnalyzer versions 6.0.10 and below, update to a version above 6.0.10 to resolve the issue. For FortiAnalyzer versions 6.2.7 and below, update to a version above 6.2.7 to resolve the issue. For FortiAnalyzer versions 6.4.3 and below, update to a version above 6.4.3 to resolve the issue. As a temporary workaround, consider restricting access to the Logview column settings in FortiAnalyzer to minimize the risk of exploitation.
