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
Format string vulnerability in the _Eventlog function in FastBackServer.exe in the Server in IBM Tivoli Storage Manager (TSM) FastBack 5.5.0.0 through 5.5.6.0 and 6.1.0.0 through 6.1.0.1 allows remote attackers to execute arbitrary code via format string specifiers located after a | (pipe) character in a string. NOTE: this might overlap CVE-2010-3059.

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

Format string vulnerability in the _Eventlog function within FastBackServer.exe in IBM TSM FastBack versions 5.5.0.0-5.5.6.0 and 6.1.0.0-6.1.0.1 allows remote attackers to execute arbitrary code by inserting format string specifiers after a pipe character in a string passed to the logging function.

MitigationUpgrade to IBM TSM FastBack version 5.5.6.1 or 6.1.0.2 and later. If patching is not immediately possible, implement network segmentation and restrict access to the FastBack Server port to minimize exposure to remote attackers.

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 the FastBackServer.exe file
    Search for FastBackServer.exe in the installation directory, typically under C:\Program Files\IBM\Tivoli\TSM FastBack\ or use 'Get-ChildItem -Path C:\ -Filter FastBackServer.exe -Recurse -ErrorAction SilentlyContinue' to find it across drives
    Affected if The file exists and is the vulnerable component
  2. Determine the FastBackServer.exe version
    Right-click the FastBackServer.exe file, select Properties, then view the Details tab for File Version, or run '(Get-Item "C:\Program Files\IBM\Tivoli\TSM FastBack\FastBackServer.exe").VersionInfo' in PowerShell
    Affected if The version falls within 5.5.0.0 through 5.5.6.0, or 6.1.0.0 through 6.1.0.1
  3. Check the installed IBM TSM FastBack product version
    Open Windows Control Panel, go to Programs and Features, locate IBM TSM FastBack in the list, and note the Version column
    Affected if The installed version matches 5.5.0, 5.5.1, 5.5.2, 5.5.2.0, 5.5.3.0, 5.5.4.0, 5.5.5.0, 5.5.6.0, 6.1.0.0, or 6.1.0.1
  4. Verify if FastBackServer service is running
    Open Services console (services.msc) and check for 'TSM FastBack Server' service status, or run 'Get-Service -Name *FastBack*' in PowerShell
    Affected if The service is running and the version is within the affected ranges

You are affected if IBM TSM FastBack version is 5.5.0.0-5.5.6.0 or 6.1.0.0-6.1.0.1 and the FastBackServer.exe component is present and running.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to IBM TSM FastBack version 5.5.6.1 or 6.1.0.2 and later. If patching is not immediately possible, implement network segmentation and restrict access to the FastBack Server port to minimize exposure to remote attackers.

Recommended fix Moderate confidence

IBM Tivoli Storage Manager FastBack 5.5.6.1 or later / 6.1.0.2 or later (or latest available version)

  1. 1. Identify the currently installed IBM Tivoli Storage Manager FastBack version by checking the FastBackServer.exe properties or using the FastBack administration console.
  2. 2. Download the appropriate IBM Tivoli Storage Manager FastBack fix from IBM Support (search for APAR IC70721 or the security bulletin for this CVE).
  3. 3. Stop all FastBack services on the server before applying the update.
  4. 4. Apply the IBM-provided patch or upgrade to FastBack version 5.5.6.1 or later (for 5.5.x branch) OR version 6.1.0.2 or later (for 6.1.x branch).
  5. 5. Restart the FastBack services after the patch is applied.
  6. 6. Verify the patch was applied successfully by checking the FastBackServer.exe version matches the fixed release.
  7. 7. Test critical backup and recovery operations to ensure the fix does not impact functionality.
Caveat Review IBM release notes for any configuration or compatibility changes between your current version and the target fixed version before upgrading.
