IBM Security Verify Access Appliance missing certificate validation

Vulnerability

IBM Security Verify Access Appliance versions 10.0.0 through 10.0.7 are vulnerable to man-in-the-middle (MITM) attacks when deploying Open Source Python scripts from the public repository at https://github.com/IBM-Security/ibmsecurity. The scripts fail to validate certificates, enabling an attacker to intercept or alter communications during deployment [1].

Exploitation

An attacker in a network position capable of intercepting traffic between the appliance and the GitHub repository can perform a MITM attack. The attacker must trick a user into running the deployment scripts while the connection is intercepted. The vulnerability is triggered when the scripts download dependencies or resources without verifying the authenticity of the server's certificate [1].

Impact

Successful exploitation allows the attacker to execute arbitrary code with the privileges of the user running the deployment scripts. This can lead to full compromise of the appliance's deployment environment, including disclosure of sensitive information, modification of configurations, or denial of service [1].

Mitigation

IBM has addressed this vulnerability in the updated deployment scripts published on GitHub. Users should immediately update to the latest version of the scripts from https://github.com/IBM-Security/ibmsecurity. No workaround is provided; updating eliminates the missing certificate validation [1].
