CVE-2023-0156Public exploitNetwork attack vector

Admin-only file disclosure via unbounded log path

Published Apr 10, 2023 · Updated Feb 11, 2025

Path traversal in TeamUpdraft All-In-One Security before 5.1.5 allows remote authenticated users to read server files. The filesystem settings page accepts aiowps_system_log_file from a POST request and reads the selected path without confining it to an allowed log directory. Administrator privileges and a valid nonce are required; output is limited to directory listings or the final 50 lines of files readable by the web server.
