PaperCut Chained RCE Flaws Actively Exploited, Emergency Patch Released
- Engineer — Act: Unauthenticated RCE via chained flaws in PaperCut NG/MF is being actively exploited; apply the emergency patch immediately and audit PaperCut server logs for unexpected Java process execution or outbound connections predating the patch.
- SOC/IR — Act: Active exploitation of PaperCut print servers means assumed-breach posture is warranted — hunt for anomalous Java child processes or unusual network activity originating from PaperCut hosts since before the emergency patch date, and check EDR telemetry on any print-management systems.
- Leader — Plan: PaperCut NG/MF is common in enterprise and education environments; confirm with engineering that all instances are patched this week and verify no lateral movement occurred from print servers — prior PaperCut exploits (2023) drew board attention, so have a status update ready if asked.
