CVE-2026-5333 Details
Description
A security flaw has been discovered in DefaultFuction Content-Management-System 1.0. This issue affects some unknown processing of the file /admin/tools.php. The manipulation of the argument host results in command injection. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks.
A command injection vulnerability has been identified in DefaultFuction Content-Management-System version 1.0.0. The issue arises in the file /admin/tools.php, where user-supplied input in the host argument is not properly validated or sanitized before being passed to system shell commands. This flaw allows remote attackers to inject arbitrary commands, which are executed on the server with the application's privileges. The vulnerability can be exploited without authentication, potentially leading to a complete compromise of the affected server.
No specific mitigation measures are known for this vulnerability. However, it is generally recommended to avoid direct execution of system commands with user input, implement strict input validation and sanitization, and run web applications with the least privileges necessary.
