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 platform allowing organizations to manage their cyber threat intelligence knowledge and observables. Due to lack of certain security controls on the profile edit functionality, an authenticated attacker with low privileges can gain administrative privileges on the web application.
OpenCTI is an open-source cyber threat intelligence platform. In versions below 6.2.18, because the function to limit the rate of OTP does not exist, an attacker with valid credentials or a malicious user who commits internal fraud can break through the two-factor authentication and hijack the account. This is because the otpLogin mutation does not implement One Time Password rate limiting. As of time of publication, it is unknown whether a patch is available.
OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to version 6.5.2, any user with the capability manage customizations can edit webhook that will execute javascript code. This can be abused to cause a denial of service attack by prototype pollution, making the node js server running the OpenCTI frontend become unavailable. Version 6.5.2 fixes the issue.
OpenCTI 3.3.1 is vulnerable to a directory traversal attack via the static/css endpoint. An unauthenticated attacker can read arbitrary files from the filesystem by sending crafted GET requests with path traversal sequences (e.g., '../') in the URL. For example, requesting /static/css//../../../../../../../../etc/passwd returns the contents of /etc/passwd. This vulnerability was discovered by Raif Berkay Dincel and confirmed on Linux Mint and Windows 10.
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 otpqr and otpactivated. 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.
OpenCTI is an open-source cyber threat intelligence platform. Before 6.3.0, general users can access information that can only be accessed by users with access privileges to admin and support information (SETTINGSSUPPORT). This is due to inadequate access control for support information (http://<openctidomain>/storage/get/support/UUID/UUID.zip), and that the UUID is available to general users using an attached query (logs query). This vulnerability is fixed in 6.3.0.
