http://secunia.com/product/15219/

DESCRIPTION:
defaultroute has reported a vulnerability in BlueCat Networks
Proteus, which can be exploited by malicious users to bypass certain
security restrictions.

The vulnerability is caused due to an input validation error within
the TFTP functionality in the Proteus Admin Interface. This can be
exploited to create or overwrite files with root privileges on an
Adonis DNS/DHCP appliance via files containing directory traversal
sequences in the file name.

Successful exploitation allows to compromise an Adonis appliance, but
requires administrative privileges with access to the TFTP services on
the Proteus system.

The vulnerability is reported in Proteus version 2.0.2.0. Other
versions may also be affected.
