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
Multiple stack-based buffer overflows 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 allow remote attackers to execute arbitrary code via vectors involving the (1) AGI_SendToLog (aka _SendToLog) function; the (2) group, (3) workgroup, or (4) domain name field to the USER_S_AddADGroup function; the (5) user_path variable to the FXCLI_checkIndexDBLocation function; or (6) the _AGI_S_ActivateLTScriptReply (aka ActivateLTScriptReply) function. 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

Multiple stack-based buffer overflow vulnerabilities exist in IBM TSM FastBack Server (versions 5.5.0.0-5.5.6.0 and 6.1.0.0-6.1.0.1). The FastBackServer.exe service contains overflows in six distinct locations: the AGI_SendToLog function, three different fields (group, workgroup, domain name) passed to USER_S_AddADGroup, the user_path variable to FXCLI_checkIndexDBLocation, and the _AGI_S_ActivateLTScriptReply function. These allow remote unauthenticated attackers to execute arbitrary code via specially crafted network packets.

MitigationUpgrade to IBM Tivoli Storage Manager FastBack version 6.1.0.2 or later, which contains the vendor patch. If immediate patching is not possible, restrict network access to the FastBack server port and disable the service if non-essential.

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 if IBM TSM FastBack Server is installed
    Check for the presence of the FastBack Server installation directory (typically in Program Files/IBM/Tivoli Storage Manager FastBack) or look for the FastBackServer.exe binary
    Affected if The FastBackServer.exe file exists on the system
  2. Identify the installed FastBack version
    Check the version of FastBackServer.exe by right-clicking the file, selecting Properties, and viewing the Details tab, or use the command: dir "C:\Program Files\IBM\Tivoli Storage Manager FastBack\FastBackServer.exe" /s
    Affected if The version matches 5.5.0.0 through 5.5.6.0 or 6.1.0.0 through 6.1.0.1
  3. Confirm if the FastBackServer service is running
    Open Services console (services.msc) and locate the FastBack Server service, or run: sc query FastBackServer
    Affected if The service status shows as RUNNING
  4. Check network exposure of the FastBack Server port
    Run netstat -an | findstr "PORT" where PORT is the FastBack Server listener port (default 11460 or 11461), or review firewall rules for inbound access to the FastBack service
    Affected if The FastBack Server port is listening on a network-facing interface and accessible from untrusted networks

A user is affected if IBM TSM FastBack Server versions 5.5.0.0-5.5.6.0 or 6.1.0.0-6.1.0.1 are installed with the FastBackServer.exe service running and exposed to the network.

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

Upgrade to IBM Tivoli Storage Manager FastBack version 6.1.0.2 or later, which contains the vendor patch. If immediate patching is not possible, restrict network access to the FastBack server port and disable the service if non-essential.

Recommended fix Moderate confidence

IBM TSM FastBack 5.5.6.1 or later, or 6.1.0.2 or later (obtain latest available from IBM)

  1. 1. Identify the current installed version of IBM TSM FastBack Server by checking the About or version information in the FastBack Manager console
  2. 2. Obtain the latest IBM Tivoli Storage Manager FastBack fix pack or interim fix from IBM Support (https://www.ibm.com/support)
  3. 3. Stop the FastBack Server service before applying the update
  4. 4. Apply the latest available fix pack or security patch for TSM FastBack
  5. 5. Restart the FastBack Server service after the patch is applied
  6. 6. Verify the server is running correctly and test critical backup/restore operations
Caveat Test the upgrade in a non-production environment first as any server patch may affect existing backup schedules or configurations
