CVE-2018-1509
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 Security Guardium EcoSystem 10.5 does not validate, or incorrectly validates, a certificate.This weakness might allow an attacker to spoof a trusted entity by using a man-in-the-middle (MITM) attack. The software might connect to a malicious host while believing it is a trusted host, or the software might be deceived into accepting spoofed data that appears to originate from a trusted host. IBM X-Force ID: 141417.
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 confidenceIBM Security Guardium EcoSystem 10.5 fails to properly validate SSL/TLS certificates, allowing an attacker performing a man-in-the-middle (MITM) attack to impersonate a trusted entity. The software may connect to malicious hosts believing them to be trusted, or accept spoofed data appearing to originate from legitimate sources.

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 Guardium versionRun the Guardium version command or check the product about information. In the Guardium CLI, this is typically done via 'show version' or through the Guardium UI under System > System Setup > General Settings > About.Affected if The installed version is exactly 10.5. Only version 10.5 is listed as affected by this CVE.
-
Locate SSL/TLS client configurationsReview Guardium configuration files and settings that control outbound SSL/TLS connections. These are typically found in the Guardium UI under Data Security settings or in configuration files controlling integration with external systems.Affected if SSL/TLS client configurations exist that either disable certificate validation, skip hostname verification, or fail to perform proper certificate chain validation.
-
Check for disabled certificate verificationInspect the SSL/TLS settings for any options labeled as 'Validate Certificates', 'Verify Hostname', or 'Check Certificate Expiration' that may be set to disabled or no.Affected if Certificate validation features are explicitly disabled, allowing connections to malicious servers impersonating trusted entities.
-
Test outbound SSL/TLS connectionsIf possible, observe network traffic from Guardium to external endpoints using SSL/TLS. Use a testing tool to present an invalid or self-signed certificate to see if Guardium accepts the connection.Affected if Guardium accepts SSL/TLS connections to servers presenting invalid, expired, or mismatched certificates without rejecting them.
You are affected only if your installed Guardium version is exactly 10.5 AND your SSL/TLS certificate validation is either disabled or improperly configured, allowing acceptance of invalid certificates.

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 dataImplement proper certificate chain validation, hostname verification, and expiration checking for all SSL/TLS connections. Apply any available vendor patches for Guardium EcoSystem 10.5.
