# CVE-2026-61515: Puwell IP Camera 2.x - 4.x Unauthenticated Command Injection via DebugShell

- Severity: CVSS 9.3 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2026-08-04 · Updated: 2026-08-05

## Affected

- Puwell Technology Inc. IP Camera: from 2.x, through 4.x

## 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.
