Description
Nagios XI versions prior to 5.7.3 contain a command injection vulnerability in the report PDF download/export functionality. User-supplied values used in the PDF generation pipeline or the wrapper that invokes offline/pdf helper utilities were insufficiently validated or improperly escaped, allowing an authenticated attacker who can trigger PDF exports to inject shell metacharacters or arguments.
