CVE-2023-31046

Estado: ModificadaMedia (6.5)—

A Path Traversal vulnerability exists in PaperCut NG before 22.1.1 and PaperCut MF before 22.1.1. Under specific conditions, this could potentially allow an authenticated attacker to achieve read-only access to the server's filesystem, because requests beginning with "GET /ui/static/..//.." reach getStaticContent in UIContentResource.class in the static-content-files servlet.
