Nagios Network Analyzer versions prior to 2024R1 contain a stored cross-site scripting (XSS) vulnerability in the Source Groups page (percentile calculator menu).

MEDIUM 5.1EPSS 0.70%

Does this matter?

Lower severity and a low EPSS score (0.70%). Track it; it rarely justifies an emergency change on its own.

Description

Nagios Network Analyzer versions prior to 2024R1 contain a stored cross-site scripting (XSS) vulnerability in the Source Groups page (percentile calculator menu). An attacker can supply a malicious payload which is stored by the application and later rendered in the context of other users. When a victim views the affected page the injected script executes in the victim's browser context.
