CRITICAL

VSee Clinic and API Exposes Cleartext SFTP Credentials in Unauthenticated HTTP Responses

Title source: cna
STIX 2.1

Description

VSee Clinic 7.1.26 and VSee Clinic API 1.3.0 exposes cleartext SFTP credentials in the HTTP responses of three unauthenticated endpoints. The credentials are present in these responses only when SFTP connections have been configured within the application. No authentication is required to retrieve these credentials. An unauthenticated remote attacker who observes any of these HTTP responses on an instance where SFTP is configured can obtain the credentials and use them to access the associated SFTP server.
