Ruby vulnerability analysis and mitigation
Overview
The twitter-bootstrap-rails Gem for Rails contains a reflected cross-site scripting (XSS) vulnerability (CVE-2014-4920). The vulnerability was discovered on March 25, 2014, affecting versions prior to 3.2.0 of the twitter-bootstrap-rails package. The flaw exists in the bootstrap_flash helper method which fails to properly validate input when handling flash messages (Ruby Advisory DB).
Technical details
The vulnerability stems from improper input validation in the bootstrap_flash helper method when processing flash messages. This method does not properly sanitize user input before returning it to users, allowing for potential script injection. The vulnerability has been assigned a Moderate severity rating (GitHub Advisory). The weakness has been classified as CWE-79, which refers to improper neutralization of input during web page generation.
Impact
A successful exploitation of this vulnerability could allow a context-dependent attacker to execute arbitrary JavaScript code in a user's browser session within the trust relationship between their browser and the server. This could potentially lead to theft of sensitive browser-based data or perform actions on behalf of the victim user (GitHub Advisory).
Mitigation and workarounds
The vulnerability has been patched in version 3.2.0 of the twitter-bootstrap-rails gem. Users should upgrade to version 3.2.0 or later to mitigate this vulnerability (GitHub Advisory).
