CVE-2020-4598
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 Insights 2.0.1 could allow a remote attacker to conduct phishing attacks, using an open redirect attack. By persuading a victim to visit a specially crafted Web site, a remote attacker could exploit this vulnerability to spoof the URL displayed to redirect a user to a malicious Web site that would appear to be trusted. This could allow the attacker to obtain highly sensitive information or conduct further attacks against the victim. IBM X-Force ID: 184823.
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 Guardium Insights 2.0.1 contains an open redirect vulnerability where the application fails to properly validate redirect URLs. An attacker can craft a malicious URL that appears to originate from the trusted IBM domain but redirects users to an attacker-controlled website, enabling phishing attacks to harvest credentials or deliver further exploits.

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 Insights versionAccess the IBM Security Guardium Insights administrative interface or check the product version via system information. Look for version display in the About section or check installed package version through system commands if available.Affected if The installed version is exactly 2.0.1 (no patches applied)
-
Confirm the web application is accessibleVerify that the Guardium Insights web interface is reachable over HTTP/HTTPS. The open redirect requires the application to be accessible to potential attackers.Affected if The application web interface is exposed and reachable
-
Verify redirect functionality existsInspect web application behavior for redirect parameters. Common redirect parameter patterns include 'redirect', 'url', 'next', 'target', or similar query parameters that control navigation. Test by submitting a request with an external domain in these parameters.Affected if The application accepts redirect parameters that can be manipulated to point to external domains
-
Review HTTP access logs for redirect abuseExamine Guardium Insights access logs for suspicious redirect patterns. Look for requests where redirect parameters contain non-IBM domains, particularly those appearing in query strings or as values to redirect-related parameters.Affected if Logs show redirect parameter values pointing to external, untrusted domains
You are affected if Guardium Insights version 2.0.1 is installed and its web interface is accessible, as the open redirect vulnerability exists in this specific version without requiring additional configuration to be exploitable.

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 security patches for Guardium Insights 2.0.1 or upgrade to a patched version. Implement strict URL validation and allowlist-based redirect logic to prevent unauthorized redirects.
