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 · unedited
IBM Data Risk Manager 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, and 2.0.6 could allow a remote attacker to bypass security restrictions when configured with SAML authentication. By sending a specially crafted HTTP request, an attacker could exploit this vulnerability to bypass the authentication process and gain full administrative access to the system. IBM X-Force ID: 180532.

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 confidence

IBM Data Risk Manager versions 2.0.1-2.0.6 contains a SAML authentication bypass vulnerability where specially crafted HTTP requests can circumvent the authentication mechanism, allowing unauthenticated attackers to gain full administrative system access.

MitigationApply IBM patches for this vulnerability and review SAML configuration settings. If no patch is available, consider disabling SAML and using alternative authentication methods until remediation is possible.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if IBM Data Risk Manager is installed
    Locate the IBM Data Risk Manager application in your environment and confirm its presence
    Affected if IBM Data Risk Manager is present in the environment
  2. Determine the installed version
    Use the product's built-in version display or check the product metadata to identify the exact version number
    Affected if The installed version falls within the range 2.0.1 to 2.0.6.1 inclusive
  3. Verify SAML authentication is enabled
    Check the product configuration or authentication settings to determine whether SAML-based authentication is active
    Affected if SAML authentication is enabled and the version is within the affected range
  4. Review admin accounts for unauthorized access
    Examine the administrative user accounts in the system for any unexpected or unauthorized accounts that may indicate exploitation
    Affected if Unexpected admin accounts exist that were not created by legitimate administrators

You are affected if IBM Data Risk Manager version 2.0.1 through 2.0.6.1 is installed with SAML authentication enabled in your environment.
