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
Audio Conversion Wizard v2.01 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting memory with a specially crafted registration code. Attackers can generate a payload that overwrites the application's memory stack, potentially enabling remote code execution through a carefully constructed input buffer.

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

Audio Conversion Wizard v2.01 suffers from a stack-based buffer overflow in its registration code validation routine. By providing an oversized input to the registration code field, attackers can overwrite the return address and adjacent stack frames, redirecting execution flow to attacker-controlled shellcode and achieving arbitrary code execution.

MitigationReplace the vulnerable registration code handling with proper bounds-checked functions (e.g., using safe string functions like strncpy_s or implementing explicit length validation), enable stack canaries during compilation, and consider migrating to modern input validation patterns.

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. Locate Audio Conversion Wizard installation
    Search for the application executable (e.g., AudioConversionWizard.exe, acw.exe, or similar) in common installation directories: C:\Program Files\, C:\Program Files (x86)\, or the user's AppData\Local folder. Use 'dir /s /b C:\*Audio*Conversion*Wizard*.exe' or file explorer search.
    Affected if The executable is found on the system
  2. Identify installed version
    Right-click the executable, select Properties, then view the Details tab for version information. Alternatively, right-click the executable in File Explorer and select Properties > Details to see Product Name and Product Version fields.
    Affected if The version is 2.01 exactly, or if version information is missing but the product name matches Audio Conversion Wizard
  3. Verify vulnerable component exists
    Attempt to launch the application and navigate to the Help menu or any registration/activation dialog. Look for a registration code input field where users enter a license key.
    Affected if The application launches and presents a registration code input field in the UI
  4. Confirm vulnerability condition
    The vulnerability is inherent to v2.01 when the registration code field accepts unbounded input. Check if the executable was compiled with modern protections by examining file properties or using tools like 'dumpbin /headers' to view compile-time security flags (ASLR, DEP).
    Affected if The application runs and accepts registration code input, and version 2.01 is confirmed without compiler security mitigations

If Audio Conversion Wizard version 2.01 is installed and the registration code input field is present and functional, the environment is affected by this buffer overflow vulnerability.
