CVE-2010-3754
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 · uneditedThe FXCLI_OraBR_Exec_Command 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 uses values of packet fields to determine the content and length of data copied to memory, which allows remote attackers to execute arbitrary code via a crafted packet. 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 confidenceThe FXCLI_OraBR_Exec_Command function in FastBackServer.exe processes packet data without proper bounds checking, using packet field values to determine the length and content of memory copy operations. This classic buffer overflow allows remote attackers to execute arbitrary code by sending specially crafted packets to the TSM FastBack server.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate the FastBackServer.exe executableSearch for FastBackServer.exe in typical installation directories such as C:\Program Files\Tivoli\TSM\FastBack\server\ or C:\IBM\Tivoli\TSM\FastBack\server\, or use the command 'dir /s C:\FastBackServer.exe' on Windows systems.Affected if The executable exists on the system, indicating IBM TSM FastBack server software is installed.
-
Determine the installed FastBack versionRight-click on FastBackServer.exe, select Properties, then view the Version tab to obtain the file version. Alternatively, run 'wmic product where "name like '%FastBack%'" get version' if available, or check the Windows registry under HKLM\SOFTWARE\IBM\Tivoli\Storage Manager\FastBack\CurrentVersion.Affected if The version matches one of the affected versions: 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.
-
Verify the FastBack server service is runningOpen Services (services.msc) and look for a service named 'Tivoli Storage Manager FastBack Server' or 'TSM FastBack Server', or run 'sc query' to list running services and filter for FastBack-related entries.Affected if The service is present and running, making the vulnerable component active.
-
Confirm network exposure of the FastBack server portRun 'netstat -an | findstr LISTENING' to identify listening ports, or use 'nmap -p- <target>' to scan for open ports. The default TSM FastBack server listens on port 11460 or similar. Check firewall rules with 'netsh advfirewall firewall show rule name=all' to see if the port is accessible from untrusted networks.Affected if The FastBack server port is open and accessible from untrusted network segments, enabling remote exploitation.
The system is affected if IBM TSM FastBack server is installed with a version matching 5.5.x or 6.1.x (specifically 5.5.0 through 5.5.6.0 or 6.1.0.0/6.1.0.1), the FastBackServer.exe service is running, and the server port is exposed to the network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply vendor-supplied patches for TSM FastBack versions 5.5.x and 6.1.x, or upgrade to a patched version. If immediate patching is not feasible, implement network segmentation and firewall rules to restrict unauthorized access to the FastBack server port.
IBM TSM FastBack 5.5.6.1 or later (5.5.x branch); IBM TSM FastBack 6.1.0.2 or later (6.1.x branch)
- 1. Identify the currently installed IBM TSM FastBack version by checking the FastBackServer.exe properties or using the FastBack client CLI.
- 2. Download the appropriate fix from IBM Fix Central using the product name 'Tivoli Storage Manager FastBack' and your existing version as the search criteria.
- 3. Apply the latest IBM interim fix or upgrade to version 5.5.6.1 or later (for the 5.5.x branch) or version 6.1.0.2 or later (for the 6.1.x branch).
- 4. After applying the fix, restart the FastBack Server service to ensure the patched code is loaded.
- 5. Verify the fix was applied successfully by checking the FastBack server version and confirming the FXCLI_OraBR_Exec_Command function is no longer vulnerable to packet field manipulation.
