CVE-2023-4922Public exploitNetwork attack vector

Unauthenticated file disclosure via unrestricted path parameter

Published Nov 27, 2023 · Updated Aug 2, 2024

Local file inclusion in WPB Show Core 2.2 and earlier allows remote attackers to read local server files via the path parameter. The download-file.php endpoint accepts an unauthenticated path value that selects an arbitrary local file without restricting access to an approved directory. Direct file reads require only network access; PHP code execution additionally requires an attacker-controlled file already present on the server.
