What to do
AI-suggested
Organizations should immediately verify whether the WebAPI.cfg.xml file exists in the IIS webroot directory and restrict access to it. This can be done by removing the file if it is not needed post-installation or moving it to a non-web-accessible location. Implement strict access controls on HTTP services, including network segmentation and firewall rules to limit access to trusted hosts only. Enforce HTTPS and disable HTTP where possible to prevent interception. Monitor web server logs for unauthorized access attempts to configuration files. Additionally, coordinate with Entrust to obtain any available patches or updated versions that address this issue. If patching is not immediately possible, consider deploying web application firewalls (WAFs) to block requests targeting the configuration file path. Regularly audit and harden IIS configurations to prevent directory traversal or path guessing attacks. Finally, educate system administrators about the risks of leaving sensitive files accessible and enforce secure installation and post-installation procedures.
Description
Entrust Instant Financial Issuance (On Premise) Software (formerly known as Cardwizard) 6.10.0, 6.9.0, 6.9.1, 6.9.2, and 6.8.x and earlier leaves behind a configuration file (i.e. WebAPI.cfg.xml) after the installation process. This file can be accessed without authentication on HTTP port 80 by guessing the correct IIS webroot path. It includes system configuration parameter names and values with sensitive configuration values encrypted.
