CVE-2024-32978

Kaminari is a paginator for web app frameworks and object relational mappings. A security vulnerability involving insecure file permissions has been identified in the Kaminari pagination library for Ruby on Rails, concerning insecure file permissions. This vulnerability is of moderate severity due to the potential for unauthorized write access to particular Ruby files managed by the library. Such access could lead to the alteration of application behavior or data integrity issues. Users of affected versions are advised to update to Kaminari version 0.16.2 or later, where file permissions have been adjusted to enhance security. If upgrading is not feasible immediately, review and adjust the file permissions for particular Ruby files in Kaminari to ensure they are only accessible by authorized user.

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

Affected Software

Potential Mitigations

• Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
• Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
