CVE-2024-1654Network attack vector

Authenticated RCE via unvalidated file path

Published Mar 14, 2024 · Updated Aug 1, 2024

Path traversal in PaperCut NG/MF allows remote authenticated users with admin access to execute arbitrary code on the application server. The generateNextFileName method uses a user-supplied path in file operations without properly validating that path. Exploitation requires an internal system identifier and details of another valid user, and successful attacks execute code with server-level privileges.
