CVE-2026-61514 Puwell Technology Inc. CVE debrief

Who should care

Defenders responsible for Puwell IP Camera devices, network administrators, and security teams should assess exposure and implement compensating controls. They should verify exposure of Puwell IP Camera firmware versions 2.x through 4.x in the environment, assess compensating controls for TCP port 23456 access, and monitor for unauthorized access attempts on TCP port 23456. Security teams should also review the supplied official advisory or CVE record to

Why it matters

CVE-2026-61514 Puwell IP Camera authentication bypass vulnerability allows unauthenticated access to device functions, requiring defenders to verify exposure and implement compensating controls.

• Verify exposure of Puwell IP Camera firmware versions 2.x through 4.x
• Assess compensating controls for TCP port 23456 access
• Monitor for unauthorized access attempts on TCP port 23456

Technical summary

The Puwell IP Camera firmware versions 2.x through 4.x contain an authentication bypass vulnerability that allows unauthenticated attackers to access device functions by sending protocol-conforming packets over TCP port 23456 without credentials. This vulnerability has a CVSS score of 9.3 and is considered CRITICAL. The vulnerability allows attackers to access live video streams, control pan and tilt motors, activate audio functions, and remotely restart the device. Defenders should prioritize verifying exposure of Puwell IP Camera firmware versions 2.x through 4.x and assessing compensating controls.

Defensive priority

Defenders should prioritize verifying exposure of Puwell IP Camera firmware versions 2.x through 4.x and assessing compensating controls, as the vulnerability allows unauthenticated access to device functions.

Recommended defensive actions

• Verify exposure of Puwell IP Camera firmware versions 2.x through 4.x in the environment
• Assess compensating controls for TCP port 23456 access
• Monitor for unauthorized access attempts on TCP port 23456
• Implement firewall rules to restrict access to TCP port 23456
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes
