|Bugzilla:||921335: CVE-2013-1857 rubygem-actionpack: sanitize_protocol: XSS Vulnerability in the helper of Ruby on Rails|
The MITRE CVE dictionary describes this issue as:
The sanitize helper in lib/action_controller/vendor/html-scanner/html/sanitizer.rb in the Action Pack component in Ruby on Rails before 2.3.18, 3.0.x and 3.1.x before 3.1.12, and 3.2.x before 3.2.13 does not properly handle encoded : (colon) characters in URLs, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted scheme name, as demonstrated by including a : sequence.
