CVE-2022-28104Public exploitNetwork attack vector

Unauthenticated arbitrary file placement

Published May 20, 2022 · Updated Aug 3, 2024

Arbitrary file upload in Foxit PDF Editor for iOS 11.3.1 allows remote attackers to place files through an unspecified interface. Neither the CNA record, Foxit's bulletin archive, nor the referenced exploit listing identifies the upload handler or the validation error that accepts attacker-selected files. NVD rates the path as network-accessible without authentication, but public evidence does not establish the destination, automatic processing, or a code-execution consequence.
