Vulnerability Key Information Summary Vulnerability Overview DefaultFunction CMS V1.0.0 contains a command injection vulnerability. This occurs when the application passes user-supplied input (e.g., , , or ) to system shell commands without proper validation, sanitization, or escaping. Attackers can inject arbitrary operating system commands by appending command separators or operators after legitimate input parameters, leading to execution of malicious commands with the privileges of the web application. Affected Scope Software Name: DefaultFunction Content Management System (CMS) Affected Version: V1.0.0 Remediation The screenshot does not include specific patch code. Recommended Actions: Developers should enforce strict input validation, sanitization, and escaping of all user inputs before passing them to system shell commands to prevent command injection attacks. POC/Exploitation Code No explicit POC code block is present in the screenshot. The description only outlines the exploitation method (appending command separators after valid parameters).
