| Description: | | RocketChat is a free and open-source communication platform. RocketChat's LiveChat API endpoints have a vulnerability that allows access to messages sent to public and private channels. RocketChat uses the method.call and method.callAnon methods for API call authentication, with the authRequired flag setting the authentication rules. Any endpoints going through method.call will require user authentication while the same endpoints if it goes through method. callAnon will not require authentication. Any sensitive function that does not require any authentication can be easily bypassed using method.callAnon whereby the attacker will get the privilege to access messages of public as well as private channels. |
