CyberRota Analysis
AI-GeneratedYamcs versions prior to 5.12.8 and 5.13.2 are vulnerable due to the lack of proper access controls in the IamApi, allowing any authenticated user to enumerate system privileges and role mappings through specific API calls. This exposure can facilitate targeted privilege escalation attacks, potentially compromising the integrity of the system. Organizations using affected versions of Yamcs should prioritize upgrading to the patched versions to mitigate this risk.

Original NVD Description
Yamcs is a mission control framework. Prior to 5.12.8 and 5.13.2, Yamcs omits SystemPrivilege.ControlAccess checks from IamApi.listRoles, IamApi.getRole, and IamApi.listPrivileges in yamcs-core/src/main/java/org/yamcs/http/api/IamApi.java. Any authenticated account can call GET /api/roles, GET /api/roles/{name}, and GET /api/privileges to enumerate available system privileges and configured role mappings. The disclosure reveals security configuration that can support targeted privilege-escalation attempts. This issue is fixed in versions 5.12.8 and 5.13.2.
