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
CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability exists that could cause a crash of the Accutech Manager when receiving a specially crafted request over port 2536/TCP.

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 CWE-120 classic buffer overflow vulnerability exists in Accutech Manager where receiving a specially crafted request over port 2536/TCP can cause a buffer overflow due to insufficient size checking during the buffer copy operation, leading to a denial of service (application crash).

MitigationImplement proper input validation and size checking before copying data into fixed-size buffers. Consider input length validation, use of safe string functions (e.g., strncpy, snprintf), or bounds checking libraries to prevent overflow conditions.

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. Verify Accutech Manager is installed
    Check for Accutech Manager installation by searching for the application in installed programs (Windows) or via command line: 'dir /s /b Accutech*' or review application inventory
    Affected if Accutech Manager software is found on the system
  2. Confirm port 2536/TCP is listening
    Run 'netstat -ano | findstr :2536' or 'ss -tlnp | grep 2536' to check if the service is bound and listening on TCP port 2536
    Affected if Port 2536/TCP shows as LISTENING state indicating the vulnerable service is active
  3. Identify the installed version
    Check the application version through: the executable properties (right-click Accutech Manager.exe > Properties > Details), registry keys if applicable, or the software's built-in About/Version dialog
    Affected if The installed version matches or falls within any affected version ranges published in the CVE advisory (compare your version against these ranges)
  4. Assess network exposure
    Determine if port 2536/TCP is accessible from untrusted networks by reviewing firewall rules: 'netsh advfirewall firewall show rule name=all' or by attempting a remote connection to the port from an external host
    Affected if Port 2536/TCP is exposed to untrusted network segments or the internet

You are affected if Accutech Manager is installed with port 2536/TCP listening and the version falls within affected ranges, especially if the port is network-accessible.
