Authorization / External Service Interaction (HTTP)
External service interaction (HTTP) is a type of authorization vulnerability where external services are exposed to malicious actors. It occurs when a web or API application interacts with an external service over HTTP, such as APIs, databases, web servers, or other services, and has not implemented proper authorization mechanisms. This can allow attackers to gain access to the external service, and can result in data leakage, data manipulation, or other malicious activities. According to the CWE directory, this vulnerability is classified as CWE-284, Improper Access Control. Further information can be found in the OWASP Testing Guide v4.
External service interaction (HTTP) can pose a serious risk to businesses if left unaddressed. If attackers are able to gain access to an external service, they can use it to steal confidential data, manipulate data, or launch other malicious activities. This can result in significant financial losses, reputational damage, and other negative consequences. It is important to properly implement access control mechanisms to prevent unauthorized access to external services.
Organizations should implement access control mechanisms to prevent unauthorized access to external services. This can include authentication, authorization, and encryption. Authentication should be used to verify the identity of users and restrict access to authorized users only. Authorization should be used to restrict access to certain services or data based on user roles. Finally, encryption should be used to protect data in transit.
