A critical Remote Code Execution (RCE) vulnerability (CVE-2025-51820) has been discovered in the Shopping Portal v1.0.
In today’s digital world, Remote Code Execution (RCE) remains one of the most dangerous web application vulnerabilities. This report highlights a critical Remote Code Execution (RCE) (CVE-2025-51820) in the Online Shopping Portal Project v1.0 by phpgurukul, Exploiting this flaw allows attackers to execute arbitrary system commands remotely, potentially leading to full system compromise.

Craft and Upload a Malicious File / Payload : Upload a malicious PHP shell or inject command execution payloads (e.g., ;whoami, ;sleep 5) depending on the context of the vulnerability.
Trigger the Payload : Access the uploaded file or vulnerable endpoint to execute your payload: http://localhost/columbans/uploads/shell.php?cmd=whoami
Confirm Command Execution : The application executes the payload and returns the command output, RCE is confirmed.
🔍 Root Cause Analysis The vulnerability stems from insufficient validation and sanitization of user-supplied input, allowing attackers to inject and execute system-level commands. In cases involving file uploads, the server fails to restrict executable file types or validate the file content, leading to direct command execution when the file is accessed.
