Nagios Log Server < 2.1.14 XSS via Snapshots Page
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
Nagios Log Server versions prior to 2.1.14 are vulnerable to cross-site scripting (XSS) via the Snapshots Page. Untrusted log content was not safely encoded for the output context, allowing attacker-controlled data present in logs to execute script in the victim’s browser within the application origin.
