CVE-2020-4167

Vulnerability

IBM Security Guardium Insights version 2.0.1 contains improper authentication mechanisms that could allow an attacker to bypass authentication. The vulnerability exists in the authentication logic of the application. No special configuration is required for the code path to be reachable; the default installation is affected.

Exploitation

An unauthenticated remote attacker can exploit this vulnerability over the network without any user interaction or privileges. The attacker sends crafted requests to the affected endpoints to bypass authentication checks, gaining unauthorized access.

Impact

Successful exploitation allows the attacker to obtain sensitive information (low confidentiality impact) and perform unauthorized actions (low integrity impact). The attacker does not gain administrative privileges but can access restricted data and execute operations that should require authentication.

Mitigation

IBM has released a fix as part of a subsequent release. Users should upgrade to the latest version of IBM Security Guardium Insights as specified in the security bulletin [1]. No workarounds are documented.
