Detail

Several vulnerabilities have been discovered in Rails, the Ruby web application framework. The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2011-0446 Multiple cross-site scripting (XSS) vulnerabilities when JavaScript encoding is used, allow remote attackers to inject arbitrary web script or HTML.

CVE-2011-0447

Rails does not properly validate HTTP requests that contain an X-Requested-With header, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks.

For the oldstable distribution (lenny), this problem has been fixed in version 2.1.0-7+lenny0.1.

For the stable distribution (squeeze), this problem has been fixed in version 2.3.5-1.2+squeeze0.1.

For the unstable distribution (sid), this problem has been fixed in version 2.3.11-0.1.

We recommend that you upgrade your rails packages.

Open Source Vulnerability Database (OSVDB)

Id	Description
70928	Ruby on Rails mail_to Helper Multiple Parameter XSS Ruby on Rails contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'name' or 'email' values upon submission to the 'mail_to' helper. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
70927	Ruby on Rails Ajax/API Request CSRF Protection Bypass Ruby on Rails contains a flaw that allows a remote Cross-site Request Forgery (CSRF / XSRF) attack. The flaw exists because the application does not require multiple steps or explicit confirmation for AJAX or API HTTP requests that contain a X-Requested-With header. This makes it easier for an attacker to use a crafted URL (e.g., a crafted GET request inside an "img" tag) to trick the victim into clicking on the image to take advantage of the trust relationship between the authenticated victim and the application. Such an attack could trick the victim into executing arbitrary commands in the context of their session with the application, without further prompting or verification.
