Details
Stored cross-site scripting (XSS) vulnerability in Gemirro allows attackers to inject arbitrary web script via a crafted JavaScript URL in the "homepage" value of a ".gemspec" file. A ".gemspec" file must be created with a JavaScript URL in the homepage value. This can be used to build a gem for upload to the Gemirro server, in order to achieve stored XSS via the author name hyperlink.
