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
The _DAS_ReadBlockReply 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 cause a denial of service (NULL pointer dereference and daemon crash) via data in a TCP packet. NOTE: this might overlap CVE-2010-3060.

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

The _DAS_ReadBlockReply function in FastBackServer.exe in IBM TSM FastBack Server contains a NULL pointer dereference vulnerability. Remote attackers can trigger this by sending specially crafted data in a TCP packet to the affected service, causing the daemon to crash and result in denial of service.

MitigationUpdate IBM TSM FastBack to a version beyond 5.5.6.0 or 6.1.0.1 as provided by IBM's security patches. If patching is immediately unavailable, consider network segmentation to limit exposure to untrusted networks.

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 FastBackServer.exe installation
    Search for FastBackServer.exe on the system using file search or check default installation paths such as C:\Program Files\IBM\Tivoli Storage Manager FastBack\server\
    Affected if FastBackServer.exe is found on the system, proceed to version check.
  2. Determine FastBackServer.exe version
    Right-click FastBackServer.exe, select Properties, then view the Details tab to see File Version. Alternatively, use the command: dir "C:\Program Files\IBM\Tivoli Storage Manager FastBack\server\FastBackServer.exe"
    Affected if The file 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.
  3. Verify FastBack Server service is running
    Open Services console (services.msc) and locate 'IBM Tivoli Storage Manager FastBack Server' service, or run: sc query FastBackServer
    Affected if The service is in a Running state, exposing the vulnerable TCP listener.
  4. Confirm network exposure of the service
    Run netstat -an | findstr LISTENING and look for ports typically used by FastBack Server (default 11460 or similar). Check firewall rules to determine if the port is accessible from untrusted networks.
    Affected if The FastBack Server TCP port is listening and accessible from network segments beyond trusted internal networks.

If FastBackServer.exe version matches any of the listed affected versions AND the service is running with an exposed TCP listener, the environment is vulnerable to CVE-2010-3755 denial of service attacks.
