CVE-2024-1223Network attack vector

Authentication bypass via hard-coded device API credentials

Published Mar 14, 2024 · Updated Sep 26, 2024

Authentication bypass in PaperCut NG/MF allows remote attackers to enumerate information through embedded-device APIs. A VendorKeys object supplies hard-coded credentials that bypass authentication to the External Devices API. Exploitation requires prior knowledge of valid usernames, device names, and an internal system key, plus a specific runtime state; exposed data is limited to API-enumerable information.
