CVE-2020-12764Public exploitNetwork attack vector

Unauthenticated file disclosure via file parameter traversal

Published May 9, 2020 · Updated Aug 4, 2024

Path traversal in Solis GNUTeca 3.8 allows remote attackers to read files through crafted file.php query parameters. The file.php endpoint accepts an unauthenticated file parameter alongside folder=/ without restricting the resolved path to the intended directory. No authentication or user interaction is required, and the documented consequence is limited to disclosure of files readable by the web application.
