FreeBSD : upnp -- multiple vulnerabilities (244c8288-cc4a-11e6-a475-bcaec524bf84)

critical Nessus Plugin ID 96163

Language:

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.

Solution

Update the affected package.
