Ruby on Rails patches more critical vulnerabilities

Those using the Ruby on Rails web application framework on their websites are being advised to update the software immediately after multiple new vulnerabilities were found. It's the second time this month that Rails has been patched because of serious flaws.

Ruby on Rails is an open-source web application development framework that is widely used across the Internet on websites including Hulu, GroupOn and Scribd.

One of the problems, CVE-2013-0156, lies in the parameter parsing code for Ruby on Rails, which would allow attackers to bypass authentication systems, perform SQL injection attacks or a denial of service attack against applications using Rails, according to an advisory on Tuesday. A SQL injection attack involves sending commands through a web-based form to a website's backend database, which, if not protected properly, can return sensitive data.
