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
ACE SECURITY WIP-90113 HD cameras contain an unauthenticated configuration disclosure vulnerability in the /web/cgi-bin/hi3510/backup.cgi endpoint. The endpoint permits remote download of a compressed configuration backup without requiring authentication or authorization. The exposed backup may include administrative credentials and other sensitive device settings, enabling an unauthenticated remote attacker to obtain information that could facilitate further compromise of the camera or connected network.

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 · high confidence

The ACE SECURITY WIP-90113 HD camera exposes a configuration backup CGI script at /web/cgi-bin/hi3510/backup.cgi that can be accessed without any authentication. An unauthenticated remote attacker can download a compressed configuration file containing administrative credentials and other sensitive device settings.

MitigationRestrict access to the vulnerable camera through firewall rules or network segmentation to prevent unauthenticated access to the /web/cgi-bin/hi3510/ backup endpoint. If available, apply vendor firmware updates; otherwise, consider replacing the device or implementing strict network isolation.

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 the camera model
    Access the device web interface or check the device label/datasheet to confirm the exact model is ACE SECURITY WIP-90113 HD camera
    Affected if The device model matches ACE SECURITY WIP-90113 HD or a closely related variant from the same vendor
  2. Confirm the backup CGI script exists
    Send an HTTP GET request to http://<device-ip>/web/cgi-bin/hi3510/backup.cgi without providing any authentication credentials
    Affected if The request returns an HTTP 200 response with a compressed file (typically .tar or .gz) instead of a 401/403 authentication error
  3. Verify the backup file contains sensitive data
    Download and decompress the returned file; examine its contents for administrative usernames, passwords, network settings, or other configuration data
    Affected if The backup file contains plaintext or easily reversible credentials for administrator accounts
  4. Check if authentication is required for the endpoint
    Compare access behavior with and without providing valid credentials to /web/cgi-bin/hi3510/backup.cgi; also test other CGI endpoints under /web/cgi-bin/hi3510/ to gauge overall authentication policy
    Affected if The backup endpoint is accessible without any session token, Basic Auth, or login cookies
  5. Review network exposure of the device
    Determine if the camera is directly accessible from untrusted networks (e.g., internet-facing) or if it sits behind a properly configured firewall that blocks external access to port 80/443
    Affected if The device HTTP interface is reachable from untrusted networks without network-level access controls

The device is affected if it is an ACE SECURITY WIP-90113 HD camera that allows unauthenticated access to /web/cgi-bin/hi3510/backup.cgi and returns a downloadable configuration backup file.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict access to the vulnerable camera through firewall rules or network segmentation to prevent unauthenticated access to the /web/cgi-bin/hi3510/ backup endpoint. If available, apply vendor firmware updates; otherwise, consider replacing the device or implementing strict network isolation.
