Unauthenticated Command Injection in Puwell IP Camera Firmware

Publication date: 2026-08-04

Last updated on: 2026-08-04

Assigner: VulnCheck

Description
Puwell IP Camera firmware versions 2.x through 4.x contains an unauthenticated command injection vulnerability that allows remote attackers to execute arbitrary operating system commands by sending a crafted JSON payload to the DebugShell interface exposed on TCP port 34567. Attackers can exploit the lack of authentication and input sanitization in the binary protocol service to pass arbitrary commands directly to the underlying operating system, achieving root-level code execution and complete device compromise.

Executive Summary

This vulnerability is an unauthenticated command injection flaw in Puwell IP Camera firmware versions 2.x through 4.x. It allows remote attackers to execute arbitrary operating system commands by sending a crafted JSON payload to the DebugShell interface on TCP port 34567. The lack of authentication and input sanitization enables attackers to pass commands directly to the underlying system, resulting in root-level code execution and full device compromise.

Detection Guidance

To detect this vulnerability, scan your network for devices exposing TCP port 34567. Use nmap with: nmap -p 34567 --script vuln <target_IP>. If the port is open, test for the DebugShell interface by sending a crafted JSON payload to trigger a response.

Impact Analysis

This vulnerability allows attackers to gain complete control over affected Puwell IP cameras. They can execute any operating system command with root privileges, potentially leading to unauthorized access, data theft, device manipulation, or use of the camera as a pivot point for further network attacks. Since the flaw is remotely exploitable without authentication, any internet-facing camera is at immediate risk.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection regulations like GDPR and HIPAA. Unauthorized access to IP cameras could lead to exposure of personal or sensitive data, violating confidentiality provisions. Organizations using affected cameras may face regulatory penalties, data breach notifications, and reputational damage due to inadequate security controls.

Mitigation Strategies

Immediately block external access to TCP port 34567 on affected devices using a firewall. Disable the DebugShell interface if possible. Update firmware to the latest version if a patch is available. Isolate vulnerable cameras from critical network segments.
