CVE-2026-55975 H.VIEW CVE debrief

Who should care

Organizations using H.View IP cameras should prioritize patching this vulnerability to prevent potential command execution attacks. The vulnerability requires authentication and elevated privileges, but its high severity score indicates that it can have a significant impact if exploited. Security teams responsible for industrial control systems (ICS) and Internet of Things (IoT) devices should be aware of this issue and take necessary actions to mitigate the risk.

Technical summary

The vulnerability in H.View IP cameras allows an authenticated user to supply unsanitized XML fields to the device's certificate generation interface. These fields are then incorporated into a backend certificate creation command without proper input validation, potentially leading to command execution with elevated privileges. The issue has a CVSS score of 8.6, indicating high severity. The CVSS vector is CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X. The weakness associated with this vulnerability is CWE-78.

Defensive priority

This vulnerability has a high severity score and requires immediate attention from organizations using H.View IP cameras. The potential impact of command execution with elevated privileges during certificate generation is significant, and defenders should prioritize patching or applying compensating controls to mitigate the risk.

Recommended defensive actions

• Apply patches or updates provided by the vendor to fix the vulnerability.
• Implement compensating controls, such as restricting access to the certificate generation interface.
• Monitor for suspicious activity related to certificate generation and command execution.
• Perform regular security audits and vulnerability assessments to identify potential weaknesses.
• Consider implementing additional security measures, such as input validation and sanitization, to prevent similar vulnerabilities.

Evidence notes

The CVE record and NVD detail provide information about the vulnerability, its severity, and potential impact. The ICS-CERT advisory (ICSa-26-176-05) and related references offer additional context and guidance for affected organizations. However, specific details about the affected products and versions are limited, and defenders may need to perform additional research to determine the scope of the vulnerability.
