Security Vulnerabilities
IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote attacker to bypass security restrictions due to improper authentication. Authentication checks are not applied consistently, which could allow protected resources to be reached without valid credentials.

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote attacker to bypass security restrictions due to improper neutralization of special elements in a request. Specially formed request parameters are not handled safely, which could allow protections to be circumvented.

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain information about internal network services due to improper validation of user-supplied URLs. Addresses supplied by users are not sufficiently restricted, so the server could be made to contact internal systems.

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information due to verbose error messages. Error responses contain more information about the system than necessary, which could help an attacker learn about the environment.

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to bypass security restrictions and access unauthorized analytics queries due to improper input validation. Request parameters are not validated sufficiently, which could allow restrictions on analytics data to be circumvented.

IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information due to server-side request forgery. When service definitions are imported, references to external resources are not sufficiently restricted, so the server could be made to request resources it should not access.

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to execute arbitrary JavaScript due to cross-site scripting. HTML content supplied by a provider is not sufficiently sanitized before it is displayed, which could allow script content to run in the user's browser.
