Detailsinfo

A vulnerability, which was classified as critical, was found in Ruby on Rails up to 3.2.12 (Programming Language Software). This affects some unknown functionality of the file lib/action_controller/vendor/html-scanner/html/sanitizer.rb of the component sanitize_css Method. The manipulation with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The sanitize_css method 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 \n (newline) characters, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via crafted Cascading Style Sheets (CSS) token sequences.

The weakness was released 03/18/2013 by Charlie Somerville as confirmed mailinglist post (oss-sec). It is possible to read the advisory at seclists.org. The public release was coordinated with the project team. This vulnerability is uniquely identified as CVE-2013-1855 since 02/19/2013. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction.
