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
Buffer overflow in the Step-by-Step Interactive Training in Microsoft Windows 2000 SP4, XP SP2 and Professional, and Server 2003 SP1 allows remote attackers to execute arbitrary code via a long Syllabus string in crafted bookmark link files (cbo, cbl, or .cbm), a different issue than CVE-2005-1212.

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

Buffer overflow in Microsoft Step-by-Step Interactive Training allows remote code execution via specially crafted bookmark link files (.cbo, .cbl, .cbm) containing an overly long Syllabus string. The vulnerability affects Windows 2000 SP4, XP SP2/Professional, and Server 2003 SP1.

MitigationApply Microsoft security patches for this vulnerability. If patching is not feasible, disable or remove the Step-by-Step Interactive Training software and block .cbo, .cbl, and .cbm file associations at the endpoint level.

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. Check if Step-by-Step Interactive Training is installed
    Look for the program in Add/Remove Programs (appwiz.cpl) or check for the directory Program Files\Microsoft Step By Step Interactive Training
    Affected if The software is installed on the system
  2. Verify .cbo file association
    Check the Windows registry under HKCR\.cbo for the default value indicating the associated application
    Affected if The .cbo extension is associated with Step-by-Step Interactive Training or shows a ProgID containing the application name
  3. Verify .cbl file association
    Check the Windows registry under HKCR\.cbl for the default value indicating the associated application
    Affected if The .cbl extension is associated with Step-by-Step Interactive Training or shows a ProgID containing the application name
  4. Verify .cbm file association
    Check the Windows registry under HKCR\.cbm for the default value indicating the associated application
    Affected if The .cbm extension is associated with Step-by-Step Interactive Training or shows a ProgID containing the application name
  5. Check for vulnerable executable version
    If the software is installed, locate the main executable (typically Train.exe or similar) in the program directory and check its file version properties
    Affected if The installed version matches any version of the affected software (all versions are vulnerable)

The system is affected if Microsoft Step-by-Step Interactive Training is installed AND one or more of the .cbo, .cbl, or .cbm file extensions are associated with that application, as this allows the specially crafted bookmark files to trigger the buffer overflow.
