Authenticated OS Command Injection in H.View HV-500S6 IP Camera Certificate Generation

IdentifiersCVE-2026-55975CWE-78

CVE-2026-55975 is an OS command injection vulnerability affecting H.View HV-500S6 IP cameras. The flaw is in the device's certificate generation interface, where authenticated users can submit XML fields that are not properly validated or sanitized before being incorporated into a backend certificate creation command. Because attacker-controlled XML data reaches an operating-system-level command context, a malicious authenticated user may inject arbitrary commands during certificate generation. The available information indicates the injected commands may execute with elevated privileges on the device.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in remote command execution on the affected IP camera with elevated privileges during the certificate generation workflow. Given the stated high impacts to confidentiality, integrity, and availability, an attacker could potentially access sensitive data on the device, alter configuration or system state, install persistent modifications, or disrupt camera operation.

Mitigation

If you can’t patch tonight, do this now.

Until patched firmware is deployed, restrict access to the certificate generation interface to only trusted administrative users and management networks, disable or avoid use of the certificate generation feature if operationally feasible, and monitor for suspicious certificate-generation activity or unexpected command execution on affected devices. Additional compensating controls include network segmentation for camera management interfaces and minimizing exposed administrative services.

Remediation

Patch, then assume compromise.

Update the H.View IP camera firmware to a vendor-provided fixed version if available. In the vulnerable certificate generation path, XML input should be strictly validated and sanitized before being passed to backend certificate creation commands. User-controlled fields should not be concatenated into shell or OS command strings; safer APIs or parameterized execution mechanisms should be used instead.
