Ruby Gem Fastreader 1.0.8 Command Execution
来源:http://vapid.dhs.org 作者:Cashdollar 发布时间:2013-03-14  
Ruby gem fastreader-1.0.8 remote code exec
3/6/2013


https://rubygems.org/gems/fastreader

if the url contains any ; characters code will be executed as the user when a web browser is launched.

for example if fastreader is fed http://www.g;id;.com id will be executed.

./fastreader-1.0.8/lib/entry_controller.rb

.strip only removes whitespace before and after the URL.

115       # open web browser
116       command = (ENV['FASTREADER_WEB'] || "open") + " {@current_entry.url.strip}"
117       `{command}`
