Description
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.
How to fix
No fixed version has been published yet. Until one is, remove or replace the package, or turn off or isolate the affected feature. This page updates when a fix ships.
