Official Description
RSA Authentication Manager versions prior to 8.4 P10 contain a stored cross-site scripting vulnerability in the Security Console.

When other Security Console administrators open the affected report page, the injected scripts could potentially be executed in their browser.
Technical Analysis
CVE-2020-5339 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
