CVE-2015-1938
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 server in IBM Tivoli Storage Manager FastBack 6.1 before 6.1.12 allows remote attackers to execute arbitrary commands via unspecified vectors, a different vulnerability than CVE-2015-1986.
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 confidenceIBM Tivoli Storage Manager FastBack versions prior to 6.1.12 contain a command injection vulnerability allowing remote unauthenticated attackers to execute arbitrary commands on the server. The attack vector is unspecified but likely involves unsanitized input being passed to system shell commands. The CVSS 10 score indicates trivial exploitability with complete system compromise potential.

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.
-
Identify IBM Tivoli Storage Manager FastBack installationCheck the installed version of IBM Tivoli Storage Manager FastBack using the vendor provided version information tools or check the program files directory for version metadataAffected if The installed version matches any of the affected versions: 6.1.0.0, 6.1.1.0, 6.1.7.2, 6.1.8.0, 6.1.8.1, 6.1.9.0, 6.1.9.1, 6.1.10.0, 6.1.10.1, 6.1.11.0, or 6.1.11.1
-
Confirm the FastBack server service is exposedDetermine if the FastBack server is accessible over the network by checking firewall rules, listening ports, and network accessibility from untrusted segmentsAffected if The FastBack server is reachable from network segments where untrusted users could send requests to it
-
Review FastBack server logs for suspicious command patternsExamine FastBack server logs for unusual or unexpected command invocations, especially those containing shell metacharacters or suspicious executablesAffected if Logs show execution of commands that were not initiated by legitimate administrative activity
You are affected if your IBM Tivoli Storage Manager FastBack version is 6.1.11.1 or earlier and the server is network accessible to untrusted users.

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 · scopedUpgrade IBM Tivoli Storage Manager FastBack to version 6.1.12 or later to remediate this vulnerability. Additionally, restrict network access to the FastBack server and monitor for indicators of compromise until the patch is applied.
IBM Tivoli Storage Manager FastBack 6.1.12 or later
- Identify the current IBM Tivoli Storage Manager FastBack version by checking the installed software or consulting the IBM Inventory
