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 was discovered in DI_8200-16.07.26A1, There is a buffer overflow in the dbsrv_asp function; The strcpy function is executed without checking the length of the string, leading to a buffer overflow.

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

A buffer overflow vulnerability exists in the dbsrv_asp function of DI_8200-16.07.26A1. The function uses the unsafe strcpy() function without validating string length, allowing an attacker to overflow the destination buffer and potentially corrupt memory or achieve code execution.

MitigationReplace strcpy() with a bounds-safe function like strncpy() or strlcpy() and implement proper length validation on all string inputs before copying.

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 device model
    Check the device label, web interface, or SNMP sysDescr for 'DI_8200' model identification
    Affected if Device is a DI_8200 series device
  2. Check firmware version
    Access the device's web interface, check system info page, or use CLI command 'show version' or 'ver' to retrieve firmware version
    Affected if Firmware version is 16.07.26A1 or earlier (no later patched version is specified)
  3. Verify dbsrv_asp function exposure
    Check if the device exposes the dbsrv_asp function via network services - scan for open ports or check web API endpoints that may invoke this function
    Affected if dbsrv_asp is accessible as a network-exposed service or web endpoint
  4. Inspect binary for vulnerable strcpy call
    If you have access to the firmware binary, use strings/grep to search for 'dbsrv_asp' and analyze the binary for unsafe strcpy usage near this function
    Affected if Binary contains dbsrv_asp function using strcpy without bounds checking

You are affected if you have a DI_8200 device running firmware version 16.07.26A1 or earlier, with the dbsrv_asp function exposed or accessible in your environment.
