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
Hitachi Kokusai Electric Newtork products for monitoring system (Camera, Decoder and Encoder) and below allows attckers to perform a directory traversal via a crafted GET request to the endpoint /ptippage.cgi. Security information ID hitachi-sec-2022-001 contains fixes for the issue.

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

Directory traversal vulnerability in Hitachi Kokusai Electric network monitoring products (Camera, Decoder, Encoder) allows remote attackers to access arbitrary files via crafted GET requests containing path traversal sequences (../) to the /ptippage.cgi endpoint. The vulnerability is exploitable remotely without authentication.

MitigationApply the vendor patch from security advisory hitachi-sec-2022-001 to affected devices. Additionally, implement input validation and sanitization on the /ptippage.cgi endpoint to reject path traversal sequences.

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 product model
    Access the device web interface or check the device label/documentation to confirm the exact model number (e.g., Hitachi Hc Ip9100hd) and confirm it is a network camera, decoder, or encoder from Hitachi Kokusai Electric.
    Affected if The device is a Hitachi Hc Ip9100hd network monitoring device or related product from Hitachi Kokusai Electric.
  2. Check the installed firmware version
    Log into the device admin interface and navigate to the firmware/version information page, or use the command-line interface and run 'show version' or similar command to retrieve the firmware build number.
    Affected if The firmware version is 1.07 or lower.
  3. Verify web interface accessibility
    Attempt to access the device web interface on the expected IP address using HTTP (port 80) or HTTPS (port 443) and confirm the /ptippage.cgi endpoint responds.
    Affected if The device web interface is exposed and the /ptippage.cgi endpoint is reachable over the network.
  4. Inspect the endpoint for path traversal vulnerability
    Send a GET request to /ptippage.cgi with path traversal sequences (e.g., ../../) and observe whether the response contains file contents from outside the intended directory or returns an error indicating the traversal was processed.
    Affected if The /ptippage.cgi endpoint processes path traversal sequences and allows access to files outside the intended document root.

You are affected if you have a Hitachi Hc Ip9100hd device (or related camera/decoder/encoder) running firmware version 1.07 or lower with the web interface and /ptippage.cgi endpoint accessible over the network.

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.

dbcve · scoped
Upgrade available Upgrade to a release after 1.07
Interim mitigation

Apply the vendor patch from security advisory hitachi-sec-2022-001 to affected devices. Additionally, implement input validation and sanitization on the /ptippage.cgi endpoint to reject path traversal sequences.

Recommended fix Moderate confidence

Firmware version greater than 1.07 (obtain exact version from hitachi-sec-2022-001)

  1. 1. Obtain the security advisory hitachi-sec-2022-001 from Hitachi Kokusai Electric's official security page or support portal.
  2. 2. Follow the remediation instructions provided in the advisory, which may include upgrading firmware to a version beyond 1.07.
  3. 3. Apply the firmware update according to Hitachi Kokusai's official upgrade procedures for the Hc Ip9100hd device.
  4. 4. After upgrading, verify that the /ptippage.cgi endpoint no longer responds to directory traversal requests.
