CVE-2020-4292
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 Information Queue (ISIQ) 1.0.0, 1.0.1, 1.0.2, 1.0.3, and 1.0.4 uses a cross-domain policy file that includes domains that should not be trusted which could disclose sensitive information. IBM X-Force ID: 176335.
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 Information Queue (ISIQ) versions 1.0.0-1.0.4 uses a cross-domain policy file (e.g., crossdomain.xml or clientaccesspolicy.xml) that includes domains that should not be trusted. This misconfiguration could allow untrusted external domains to make cross-origin requests to ISIQ, potentially exposing sensitive information to unauthorized parties.

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.
-
Verify ISIQ version is affectedLocate the ISIQ installation directory and check the version file or product metadata. Common locations may include installation logs, version.info, or the product dashboard. Run: isiq --version or check the IBM installation directory for version information.Affected if The installed version is 1.0.0, 1.0.1, 1.0.2, 1.0.3, or 1.0.4
-
Locate crossdomain.xml policy fileSearch for crossdomain.xml in the ISIQ web root or application directory. Common paths include: /webapps/isiq/ or the main install directory. Run: find . -name crossdomain.xml 2>/dev/nullAffected if The file exists in the ISIQ deployment directory
-
Locate clientaccesspolicy.xml policy fileSearch for clientaccesspolicy.xml in the ISIQ installation. Run: find . -name clientaccesspolicy.xml 2>/dev/nullAffected if The file exists in the ISIQ deployment directory
-
Inspect crossdomain.xml contentsOpen the crossdomain.xml file and examine the <allow-domain> entries. Look for any domain declarations that are not explicitly trusted or are overly broad (such as '*', '*.untrusted.com', or unknown third-party domains).Affected if The policy contains '*' wildcard, untrusted domains, or domains not required for legitimate business functionality
-
Inspect clientaccesspolicy.xml contentsOpen the clientaccesspolicy.xml file and examine the <allow-domain> entries. Review each domain grant for necessity and trustworthiness.Affected if The policy contains untrusted domains or overly permissive access rules
The environment is affected if ISIQ version is 1.0.0-1.0.4 AND either crossdomain.xml or clientaccesspolicy.xml contains untrusted or overly permissive domain entries.

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 dataReview and restrict the cross-domain policy file to only include trusted domains. Remove any domains that are not required for legitimate business functionality, and ensure the policy follows the principle of least privilege.
