CVE-2026-55975: H.View IP Camera Privilege Escalation Flaw

CVE-2026-55975 Overview

CVE-2026-55975 is an OS command injection vulnerability [CWE-78] affecting H.View IP cameras. The flaw resides in the device's certificate generation interface, which incorporates unsanitized XML field values directly into a backend certificate creation command. An authenticated user can supply crafted XML input that breaks out of the intended argument context and executes arbitrary operating system commands with elevated privileges.

Critical Impact
Authenticated attackers can execute arbitrary commands with elevated privileges on affected H.View IP cameras, leading to full device compromise and potential pivoting into monitored networks.

Affected Products

H.View IP cameras exposing the certificate generation interface
Devices covered by CISA ICS Advisory ICSA-26-176-05

Technical Details for CVE-2026-55975

Vulnerability Analysis

The vulnerability is an OS command injection issue [CWE-78] in the certificate generation workflow of H.View IP cameras. When an authenticated user submits certificate parameters, the device parses XML fields and passes their contents into a shell command that invokes the underlying certificate creation utility. The backend does not validate or escape shell metacharacters within the XML values.

An attacker who has valid credentials on the device can inject shell operators such as backticks, semicolons, or command substitution sequences into XML fields. The injected payload is interpreted by the shell during certificate generation, producing command execution in the context of the certificate service, which runs with elevated privileges on the camera's operating system.

Because the interface is reachable over the network and the underlying process runs with high privileges, successful exploitation results in complete compromise of the confidentiality, integrity, and availability of the device. Attackers can retrieve video feeds, modify device configuration, disable the camera, or use it as a foothold into internal networks.

Root Cause

The root cause is missing input sanitization on XML fields consumed by the certificate generation routine. Field values are concatenated into a shell command string rather than being passed as isolated arguments to an execve-style API. No allowlist, escaping routine, or safe subprocess invocation is applied before command construction.

Attack Vector

The attack vector is network-based and requires authenticated access to the camera's management interface. The attacker submits a certificate generation request whose XML payload contains shell metacharacters embedded in one or more certificate fields. During processing, the injected characters terminate the intended command context and append attacker-controlled commands, which execute on the device.

No verified public exploit code is available at the time of publication. Refer to the CISA ICS Advisory ICSA-26-176-05 for additional technical detail.

Detection Methods for CVE-2026-55975

Indicators of Compromise

Unexpected child processes spawned by the certificate generation service on affected cameras
Certificate generation requests containing shell metacharacters such as ;, |, &&, backticks, or $() in XML fields
Outbound network connections from IP cameras to unfamiliar hosts following certificate operations
Modified or newly created files in system directories outside of typical firmware update paths

Detection Strategies

Inspect HTTP or HTTPS traffic destined for the camera's certificate management endpoint and flag XML payloads containing shell metacharacters
Baseline normal certificate generation activity and alert on requests occurring outside expected administrative windows
Review authentication logs for privileged user sessions that immediately precede certificate generation calls
Correlate camera command-and-control indicators with network flow data using an intrusion detection system

Monitoring Recommendations

Aggregate camera and network logs into a central SIEM or data lake for correlation with endpoint telemetry
Monitor for anomalous outbound traffic from IP camera VLANs, which typically should not initiate arbitrary internet connections
Track configuration changes on IP cameras and alert on unauthorized certificate or firmware modifications

How to Mitigate CVE-2026-55975

Immediate Actions Required

Restrict network access to the camera management interface to trusted administrative hosts only, using firewall or VLAN segmentation
Rotate administrative credentials on all H.View IP cameras and enforce strong, unique passwords per device
Disable or restrict access to the certificate generation interface until a vendor patch is applied
Audit user accounts on affected cameras and remove any unnecessary privileged accounts

Patch Information

No patch information is published in the NVD entry at the time of writing. Consult the CISA ICS Advisory ICSA-26-176-05 and the HView Smart contact page for vendor updates and remediation guidance. The full advisory data is also available in the CISA CSAF JSON file.

Workarounds

Place affected cameras on an isolated management VLAN with no direct internet exposure
Require VPN or jump-host access for any administrative interaction with the camera web interface
Deploy network intrusion detection signatures that block XML payloads containing shell metacharacters targeting the certificate endpoint
Monitor camera behavior for signs of compromise and be prepared to reimage devices from known-good firmware
