CVE-2023-33493Network attack vector

Site takeover via unauthenticated file explorer

Published Aug 1, 2023 · Updated Oct 21, 2024

Unrestricted file upload in RSI ajaxmanager through 2.3.0 allows remote attackers to place dangerous files through its exposed explorer. The module leaves its bundled file explorer reachable without login, and a bypass defeats the optional password check, exposing file, database, console, port-scan, and server-information functions. No account or user interaction is required; uploaded malware or the exposed console grants site administration and permits disclosure, modification, or deletion of site files and data.
