Improper Access Control Affecting kaminari package, versions >=0.15.0, <0.16.2

kaminari is a Scope & Engine based, clean, powerful, agnostic, customizable and sophisticated paginator for Rails 4+.

Affected versions of this package are vulnerable to Improper Access Control due to improper handling of file permissions. An attacker can modify application behavior or compromise data integrity by writing to specific Ruby files.

Note

Those who use the gem install command, such as gem install kaminari -v 0.16.1, gem unpack kaminari -v 0.16.1, or bundle install to download the package would not be affected and no action is required.

Those who manually download and decompressing the affected versions are advised to update to 0.16.2 or later version of Kaminari where file permissions have been adjusted to enhance security.

If upgrading is not feasible immediately, manually adjusting the file permissions on the server to 644 to restrict access is a viable interim measure.

All Affected Versions:

lib/kaminari/models/page_scope_methods.rb

In addition to the previously mentioned file, security tools like AWS Inspector might also identify other files as unsafe. These files, although not loaded or used at runtime, may still be flagged. To avoid any potential confusion in your logs and ensure system integrity, it is recommended to update the permissions for these files as well. This proactive measure helps maintain a clean security posture and minimizes unnecessary alerts.
