What is CVE-2011-2197?
CVE-2011-2197 is a medium-severity cross-site scripting vulnerability in Rubyonrails Rails, published on 30 Jun 2011. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
The cross-site scripting (XSS) prevention feature in Ruby on Rails 2.x before 2.3.12, 3.0.x before 3.0.8, and 3.1.x before 3.1.0.rc2 does not properly handle mutation of safe buffers, which makes it easier for remote attackers to conduct XSS attacks via crafted strings to an application that uses a problematic string method, as demonstrated by the sub method.
