CVE-2026-55975 in HV-500S6 IP Camera
Summary
by MITRE • 06/27/2026
A vulnerability exists in H.View IP cameras that could allow an authenticated user to supply unsanitized XML fields to the device's certificate generation interface, which are incorporated into a backend certificate creation command without proper input validation. This may allow for command execution with elevated privileges during certificate generation.

This vulnerability in H.View IP cameras represents a critical command injection flaw that exploits improper input sanitization within the device's certificate generation functionality. The issue arises when authenticated users can manipulate XML fields through the certificate interface, which are then directly incorporated into backend certificate creation commands without adequate validation or sanitization processes. This design flaw creates an avenue for arbitrary code execution with elevated privileges during the certificate generation process, potentially allowing attackers to gain system-level control over affected devices.
The technical implementation of this vulnerability aligns with common command injection patterns identified in CWE-77 and CWE-94 categories, where user-supplied data is improperly incorporated into system commands without proper sanitization. The authenticated nature of the attack vector suggests that an adversary must first establish credentials to exploit this weakness, but once achieved, the privilege escalation aspect allows for execution with elevated permissions typically reserved for system administrators or device management processes. This vulnerability operates at the intersection of input validation failures and privilege escalation mechanisms within embedded network security devices.
The operational impact of this vulnerability extends beyond simple unauthorized access to encompass full system compromise capabilities. Attackers could potentially execute malicious commands that modify device configurations, install backdoors, exfiltrate sensitive data, or establish persistent access points within network environments where these cameras are deployed. Given that IP cameras often serve as entry points for broader network infiltration attempts, this vulnerability could facilitate lateral movement and privilege escalation throughout connected systems, particularly in industrial control environments where such devices may be interconnected with critical infrastructure.
Mitigation strategies should focus on implementing robust input validation mechanisms and sanitization processes within all certificate generation interfaces. Organizations must ensure that XML data submitted to these components undergoes comprehensive filtering and validation before being processed by backend systems. The implementation of principle of least privilege principles is essential, ensuring that certificate generation processes operate with minimal required permissions rather than elevated system privileges. Additionally, regular firmware updates should be prioritized, as this vulnerability likely affects multiple device models within the H.View product line. Network segmentation and monitoring solutions should be deployed to detect anomalous certificate generation activities that may indicate exploitation attempts, aligning with ATT&CK technique T1059 for command and scripting interpreter usage and T1566 for credential harvesting through social engineering or system compromise approaches.
