AI-analyzed exploit summary This Metasploit module exploits a chain of vulnerabilities in IBM Data Risk Manager (CVE-2020-4427, CVE-2020-4428, CVE-2020-4429) to achieve unauthenticated remote code execution as root. It bypasses authentication, injects commands, and abuses an insecure default password.

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.
