OpenCTI is an open cyber threat intelligence (CTI) platform. Prior to version 6.4.11 any user with the capability `manage customizations` can execute commands on the underlying infrastructure where OpenCTI is hosted and can access internal server side secrets by misusing the web-hooks. Since the malicious user gets a root shell inside a container this opens up the the infrastructure environment for further attacks and exposures. Version 6.4.11 fixes the issue.
OpenCTI is an open-source cyber threat intelligence platform. In versions starting from 6.4.8 to before 6.4.10, the allow/deny lists can be bypassed, allowing a user to change attributes that are intended to be unmodifiable by the user. It is possible to toggle the `external` flag on/off and change the own token value for a user. It is also possible to edit attributes that are not in the allow list, such as `otp_qr` and `otp_activated`. If external users exist in the OpenCTI setup and the information about these users identities is sensitive, the above vulnerabilities can be used to enumerate existing user accounts as a standard low privileged user. This issue has been patched in version 6.4.10.
