Description
Description:
A Server-Side Request Forgery (SSRF) vulnerability has been identified in the messageBirdService.requestByID methods, which is utilized across various client calls in the MessageBird API, such as MessageBirdClient.verifyToken(String id, String token).
The issue arises when the id parameter, passed to the requestByID method, is not properly validated or sanitized. This allows an attacker to manipulate the id parameter to send arbitrary authenticated requests, potentially leading to unauthorized access to internal endpoints.
For example, if the id parameter is untrusted or user-controlled, an attacker can exploit this by supplying a path traversal string like "../../../<SOME_PATH>", which could be used to access unintended resources.
Affected Functions:
messageBirdService.requestByID
MessageBirdClient.verifyToken(String id, String token)
Any other client calls relying on requestByID
Impact:
An attacker can exploit this vulnerability to:
Send arbitrary authenticated requests to internal or external services.
Access sensitive data by manipulating request parameters.
Potentially compromise the security of the underlying system.
Recommendations:
To mitigate this vulnerability, it is recommended to implement some sort of input Validation:
A strong recommendation is to enforce that the id follows a UUID format (e.g., xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx), which can prevent arbitrary input manipulation.
