CVE-2023-43269Network attack vector

Unauthenticated arbitrary file write via undisclosed handler

Published Oct 5, 2023 · Updated Sep 19, 2024

Arbitrary file upload in PigCMS 7.0 and earlier allows remote attackers to write attacker-chosen files via network requests. The CNA and NVD records do not identify the affected upload handler, accepted request field, path controls, or file-validation failure. No authentication or user interaction is required, but the published evidence does not establish code execution or a particular destination.
