CVE-2020-11082:Code Injection Vulnerability in Kaminari Pagination Links

splash
Back

Description Preview

In Kaminari versions before 1.2.1, a code injection vulnerability exists that allows attackers to inject arbitrary code into pages containing pagination links. This vulnerability could potentially lead to cross-site scripting (XSS) attacks, allowing malicious actors to execute arbitrary JavaScript in users' browsers when they interact with affected pagination components.

Overview

Kaminari is a popular Ruby gem used for pagination in Ruby on Rails applications. The vulnerability affects all versions prior to 1.2.1 and stems from insufficient sanitization of user input in pagination links. When pagination links are rendered, the library fails to properly escape or sanitize certain parameters, allowing attackers to inject malicious code that gets executed in the context of the user's browser. This could lead to session theft, credential harvesting, or other client-side attacks against users of applications that implement Kaminari pagination.

Remediation

To address this vulnerability, users should update Kaminari to version 1.2.1 or later. The update can be performed by modifying the Gemfile in Rails applications:

  1. Update the Kaminari gem specification in your Gemfile: gem 'kaminari', '>= 1.2.1'

  2. Run bundle update kaminari to apply the changes

  3. Restart your application servers to ensure the updated version is loaded

For users who cannot immediately update, implementing Content Security Policy (CSP) headers may provide some mitigation against the exploitation of this vulnerability, though updating remains the recommended solution.
