InATeam has discovered two vulnerabilities in Zomplog, which can be exploited by malicious people to bypass certain security restrictions and to compromise a vulnerable system.

1) An error exists in the file upload functionality due to admin/upload_files.php not checking file extensions properly. This can be exploited to upload files with arbitrary extensions (e.g. ".php") and execute arbitrary PHP code on the server.

2) The problem is that admin/upload_files.php does not properly check for authentication. This can be exploited to access the file upload functionality by accessing the script directly.

The vulnerabilities are confirmed in version 3.8.1. Other versions may also be affected.

Solution
Restrict access to admin/upload_files.php (e.g. with a ".htaccess" file).
