CVE-2025-28389 Details
Description
Weak password requirements in OpenC3 COSMOS v6.0.0 allow attackers to bypass authentication via a brute force attack.
A vulnerability in OpenC3 COSMOS version 6.0.0 allows attackers to bypass authentication by exploiting weak password requirements. The application supports clear-text passwords, which can be brute-forced more easily than hashed passwords, especially since OpenC3 permits passwords as short as eight characters. Additionally, there are undocumented service accounts that can be leveraged for authentication.
It is recommended to eliminate the use of clear-text passwords in the authentication process and to document the existence and management of service account passwords.
