Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Matthew Garett reports :

Reported this to upstream 8 months ago without response, so: libupnp's
default behaviour allows anyone to write to your filesystem.
Seriously. Find a device running a libupnp based server (Shodan says
there's rather a lot), and POST a file to /testfile. Then GET
/testfile ... and yeah if the server is running as root (it is) and is
using / as the web root (probably not, but maybe) this gives full host
fs access.

Scott Tenaglia reports :

There is a heap buffer overflow vulnerability in the create_url_list
function in upnp/src/gena/gena_device.c.
