SYSTEM code execution via unvalidated image path
Published May 14, 2024 · Updated Sep 26, 2024
Path traversal in PaperCut NG/MF before 23.0.9 allows local users to execute code as SYSTEM through the Web Print image handler. The image-handler process uses a user-supplied path in file operations without proper validation, allowing creation at attacker-chosen locations. Exploitation requires low-privilege code execution on a Windows server where the Web Print Server service is enabled and results in SYSTEM-context execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
