H.VIEW IP cameras vulnerable to command injection
Two vulnerabilities in H.VIEW HV-500S6 IP cameras allow authenticated attackers to execute arbitrary code and upload malicious files with persistent system access.
CISA has disclosed two vulnerabilities affecting H.VIEW HV-500S6 IP cameras running firmware version IPCAM_V4.06.88.251229. CVE-2026-55975 is an OS command injection flaw in the certificate generation interface that allows authenticated users to inject unsanitized XML fields, leading to command execution with elevated privileges. CVE-2026-56414 permits authenticated users to upload arbitrary files to persistent filesystem locations without validation, potentially compromising system integrity across reboots.
Both vulnerabilities require authentication but could enable attackers to gain full control of affected devices. H.VIEW did not respond to CISA's coordination attempts, and no patches are currently available. The devices are deployed worldwide in commercial facilities.
CISA recommends isolating affected cameras from the internet, placing them behind firewalls, and using VPNs for remote access. Organizations should contact H.VIEW directly for support. No active exploitation has been reported to CISA at this time.

Detection guidance
Possible OS Command Injection Attempt Against Embedded Device Web Interface
Detects HTTP requests containing shell metacharacters or command chaining sequences within XML/certificate-related parameters, consistent with the H.VIEW HV-500S6 command injection flaw (CVE-2026-55975) where unsanitized XML fields are passed to a system shell. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

Suspicious Arbitrary File Upload to Embedded Device Persistent Storage
Detects HTTP POST/multipart upload requests to device administration endpoints delivering files with executable or script extensions, consistent with unauthenticated persistence via arbitrary file upload (CVE-2026-56414) on H.VIEW IP cameras. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.
