CVE-2016-2878
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 · uneditedMultiple cross-site request forgery (CSRF) vulnerabilities in IBM QRadar SIEM 7.1 before MR2 Patch 13 and 7.2 before 7.2.7 allow remote attackers to hijack the authentication of arbitrary users for requests that insert XSS sequences.
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 confidenceMultiple CSRF vulnerabilities in IBM QRadar SIEM allow remote attackers to forge requests that insert malicious XSS sequences while hijacking the authentication of arbitrary users. The vulnerabilities exist in versions 7.1 before MR2 Patch 13 and 7.2 before 7.2.7, where insufficient anti-CSRF protections enable authenticated users to be targeted.

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.
-
Determine installed QRadar versionLog into the QRadar console and navigate to the Admin > System Settings > Server Summary, or run the command 'qradar_version' via SSH to retrieve the exact version and patch levelAffected if The version shows 7.1.0 through 7.1 MR2 Patch 12, or 7.2.0 through 7.2.6 (versions before 7.1 MR2 Patch 13 or 7.2.7)
-
Verify web interface accessibilityConfirm that the QRadar web console (HTTPS port 443) is exposed to network users or external systemsAffected if The web interface is accessible and the system is running a vulnerable version listed above
-
Identify authentication mechanismsReview system configuration to confirm user authentication is enabled for the web console, as CSRF attacks require authenticated sessionsAffected if Users can authenticate to the QRadar web interface and the version is in the vulnerable range
You are affected if your QRadar SIEM version is 7.1.0 through 7.1 MR2 Patch 12 or 7.2.0 through 7.2.6 and the web console is accessible to users or attackers who could trigger the CSRF vulnerability.

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 patches: upgrade to 7.1 MR2 Patch 13 or later, or 7.2.7 or later. Validate CSRF tokens on state-changing requests and implement SameSite cookie attributes as defense-in-depth.
