Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability exists in H.View IP cameras certificate-related upload interfaces allow authenticated users to store arbitrary file content to fixed, persistent filesystem locations without validating file type, structure, or size. This design omission enables the placement of unexpected or malformed data in locations intended for trusted certificate material, which could affect system integrity or behavior even after reboot.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

H.View IP cameras contain a certificate upload interface that allows authenticated users to write arbitrary files to fixed persistent filesystem locations without validating file type, structure, or size. This enables an authenticated attacker to overwrite certificate storage locations with malicious content, potentially achieving code execution or persistent system compromise.

MitigationRestrict access to certificate upload interfaces to trusted administrators only and implement strict file type, size, and content validation before writing to filesystem locations. Consider adding cryptographic signature verification for certificate files.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify H.View IP cameras in your environment
    Review your network inventory, device discovery logs, or DHCP lease tables for H.View brand IP cameras. Check device web interfaces or management consoles for 'H.View' branding.
  2. Confirm access to the certificate upload interface
    Log into the camera web interface and navigate to the certificate or TLS settings section (often under Settings, Network, or Security). Check if a certificate upload or import option exists.
  3. Check authentication requirements for certificate upload
    Examine whether the certificate upload function requires administrator-level authentication. Try accessing the upload interface with different privilege levels to confirm elevated access is enforced.
  4. Inspect certificate storage locations
    If you have administrative access via SSH or telnet, examine the filesystem paths where certificates are stored (commonly /etc/ssl, /var/etc, or similar directories). Check file permissions on these directories.
  5. Check for file validation in upload functionality
    Attempt to upload a file with an unexpected extension (e.g., .txt or .sh) through the certificate upload interface. Observe whether the system accepts or rejects the file based on type, size, or content validation.

You are affected if H.View IP cameras with an exposed, authenticated certificate upload interface exist in your environment and the upload function lacks proper file type, size, and content validation.

Mitigation

Restrict access to certificate upload interfaces to trusted administrators only and implement strict file type, size, and content validation before writing to filesystem locations. Consider adding cryptographic signature verification for certificate files.
