CVE-2009-2816 Information

Description

The implementation of Cross-Origin Resource Sharing (CORS) in WebKit as used in Apple Safari before 4.0.4 and Google Chrome before 3.0.195.33 includes certain custom HTTP headers in the OPTIONS request during cross-origin operations with preflight which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via a crafted web page.
