CVE-2023-47742
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 · uneditedIBM QRadar Suite Products 1.10.12.0 through 1.10.18.0 and IBM Cloud Pak for Security 1.10.0.0 through 1.10.11.0 could disclose sensitive information using man in the middle techniques due to not correctly enforcing all aspects of certificate validation in some circumstances. IBM X-Force ID: 272533.
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 QRadar Suite Products and Cloud Pak for Security fail to properly validate SSL/TLS certificates in certain scenarios, allowing a man-in-the-middle attacker to intercept encrypted communications and disclose sensitive information. The vulnerability stems from incomplete certificate chain validation, possibly missing hostname verification or trust anchor checks.

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 the installed IBM productDetermine whether your environment is running IBM QRadar Suite or IBM Cloud Pak for Security. Check your installation documentation, product dashboard, or running services to confirm which product is deployed.Affected if The product is either QRadar Suite or Cloud Pak for Security
-
Determine the installed versionLocate the version number for the installed product. This is typically available in the product's web UI under About/Help, or via command line tools such as 'ibmcpd -v' or 'qradarctl version' if applicable to your deployment.Affected if The version cannot be determined or the product is not from the QRadar Suite or Cloud Pak for Security family
-
Compare version against affected rangesCheck if your installed version falls within: Cloud Pak for Security 1.10.0.0 through 1.10.11.0, or QRadar Suite 1.10.12.0 through 1.10.18.0. If your version is below the lower bound or above the upper bound of these ranges, it may not be affected.Affected if The installed version is >= 1.10.0.0 and <= 1.10.11.0 for Cloud Pak, or >= 1.10.12.0 and <= 1.10.18.0 for QRadar Suite
-
Identify SSL/TLS enabled componentsDetermine which components or integrations in your deployment use SSL/TLS for external communications. Review configuration files, web service settings, or API endpoints that establish encrypted connections.Affected if SSL/TLS communications are enabled and used for outbound or inbound connections to external systems
-
Verify certificate validation configurationInspect the SSL/TLS configuration for the identified components. Look for settings that control certificate chain validation, hostname verification, and trust anchor verification. Check if the system is configured to skip or weaken these checks.Affected if Certificate validation is disabled, incomplete, or configured to accept untrusted certificates
Your environment is affected if you are running Cloud Pak for Security version 1.10.0.0-1.10.11.0 or QRadar Suite version 1.10.12.0-1.10.18.0 and you have SSL/TLS communications enabled with incomplete certificate validation configured.

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 vendor patches to upgrade QRadar Suite to version 1.10.18.1 or later, and Cloud Pak for Security to version 1.10.12.0 or later. Until patches are applied, avoid untrusted networks and implement network segmentation to reduce MITM attack surface.
