Subject: CVE Request -- Sahana

Hello Steve, vendors,

   Greg Miernicki reported a security issue in Sahana disaster management
system:

Sending a specially-crafted URL (with null character included
in the string) to Sahana, would allow an attacker to access any
file on the web server.

More from Greg:

"The first issue would allow an attacker to touch/modify any file on the system.
  Essentially the issue is that get, post, and requests aren't sanitized or
  unescaped."
