IBM Data Risk Manager Security Bypass Vulnerability

IBM · Data Risk Manager

Summary

IBM Data Risk Manager (versions 2.0.1 through 2.0.6) contains a security bypass flaw in its authentication handling for deployments configured with SAML authentication. An attacker with only network access to the product can send a specially crafted HTTP request to get past the authentication process and obtain full administrative access, with no credentials and no user interaction required.

Official description · NVD

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.
