QVidium Opera11 CVE-2025-63213 Pre-Auth RCE via Command Injection

Key Information Summary Vulnerability Overview Vulnerability ID: CVE-2025-63213 Description: QVidium Opera11 device (firmware version 2.9.0-Ax4x-opera11) is vulnerable to Remote Code Execution (RCE) due to improper input validation on the /cgi-bin/net_ping.cgi endpoint. Vendor Information Vendor: QVidium Vendor Homepage: QVidium Affected Products/Codebases Product: QVidium Opera11 Affected Firmware/Software Versions: - System Serial Number: GJ4113D0597141 - Software Version: 2.9.0-Ax4x-opera11 - Kernel Version: 2.6.23.17_stm23_0125-amino - Application Version: QVidium IP Proxy v1.0.0-10 (Sun Sep 15 23:11:05 PDT 2013) Vulnerable Endpoint /cgi-bin/net_ping.cgi Attack Type Type: Remote Code Execution (RCE) Classification: Command Injection Impact Severity: High Description: - The device is vulnerable to Remote Code Execution (RCE) due to improper input validation on the /cgi-bin/net_ping.cgi endpoint. - An attacker can inject arbitrary commands by sending a specially crafted GET request with malicious parameters. - These commands will be executed with root privileges, leading to full control of the device. Affected Components: - Command Execution: Unvalidated user input in /cgi-bin/net_ping.cgi leads to RCE. - Privilege Escalation: Commands are executed with root privileges. Attack Vector Access Method: Remote, via HTTP Authentication Required: No (unauthenticated) Exploit Complexity: Low (requires only a specially crafted URL) Proof of Concept (PoC) Exploit: Remote command injection via /cgi-bin/net_ping.cgi Reproduction Steps: 1. Confirm the presence of a vulnerable QVidium Opera11 device. 2. Send a GET request with a specially crafted parameter to inject malicious commands: - Notes: - {target} = IP address or domain of the vulnerable device - {command} = Shell command to be executed 3. Example: Execute command: - Note: This request will return the result of the injected command executed with root privileges. Vulnerability Type Information Vulnerability Type: - Command Injection - Remote Code Execution (RCE) CWE ID: - CWE-78 - Improper Neutralization of Special Elements in OS Commands (Command Injection) - CWE-94 - Improper Control of Generation of Code (Code Injection) Patches and Recommended Fixes 1. Input Validation - All user inputs must be properly sanitized and validated before executing system commands. - Implement a whitelist approach, allowing only specific values in user input and blocking special characters such as , , , etc. 2. Principle of Least Privilege - Ensure that the web server or backend process executing commands does not run with root privileges. - Apply the principle of least privilege to limit potential damage from exploitation. 3. Use Prepared Statements - Avoid directly executing shell commands based on user input. - Use secure system APIs or libraries for interacting with system commands, such as in Python. 4. Security Patch - Update firmware and software to a secure version that fixes this vulnerability. Mitigation and Incident Response Before a patch is available, administrators should: - Block external access to the /cgi-bin/net_ping.cgi endpoint using firewall rules or network segmentation. - Restrict access to the management interface to trusted IP addresses only. - Monitor logs for any suspicious activity or attempts to exploit this vulnerability.
