CVE-2015-4956
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 Web UI in IBM Security QRadar SIEM 7.1.x before 7.1 MR2 Patch 12 allows remote authenticated users to execute unspecified OS commands via unknown vectors.
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 Security QRadar SIEM versions 7.1.x before 7.1 MR2 Patch 12 contain a command injection vulnerability in the Web UI component. This allows remote authenticated users to execute arbitrary operating system commands on the underlying host, potentially leading to full system compromise.

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 installed QRadar SIEM versionAccess the QRadar admin console or use the command line interface to retrieve the current software version. Typically found in the system settings or via 'qradar_version' command output.Affected if The installed version falls within 7.1.0 through 7.1 MR2 Patch 11 inclusive, meaning it is earlier than 7.1 MR2 Patch 12.
-
Confirm Web UI component is enabledVerify that the QRadar Web UI (console interface accessible via browser on port 443 or 4433) is actively running and accessible on the network.Affected if The Web UI component is exposed and running, as this is the attack vector for the command injection flaw.
-
Check remote authentication configurationReview QRadar authentication settings to determine if remote user authentication to the Web UI is permitted. This includes local user accounts, LDAP, or other identity providers integrated with QRadar.Affected if Remote authentication is enabled and remote users can log into the Web UI, as authenticated access is required to exploit this vulnerability.
A user is affected if their QRadar installation version is 7.1.0 through 7.1 MR2 Patch 11 inclusive, the Web UI is accessible, and remote authentication to the Web UI is permitted.

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.
From vendor dataApply IBM QRadar SIEM version 7.1 MR2 Patch 12 or later to resolve this vulnerability. If immediate patching is not possible, restrict network access to the QRadar Web UI to trusted administrative IPs only.
