Ignite-UX is an HP-UX administration toolset to help users:

Details
- -------
As part of the installation process, HP Ignite-UX can install and enable a TFTP server to
facilitate anonymous access to configuration data. It is with this service that the following
vulnerabilities arise from.

However please note that several factors must be correct to take advantage of these
vulnerabilities remotely:

. This only affects machines that are running certain version of HP-UX
. These affected machines have the TFTP server running
. The TFTP server is accessible externally
. A specific command is executed

151204/NISCC/IGNITE-UX/1
CVE ID: CAN-2004-0952

In certain circumstances when the add_new_client command is used, some sections of the TFTP server
tree can become world-writeable. This can allow a malicious person to use it as a mechanism for
moving objects into and out of the system, or simply launch a denial-of-service attack against the
host by filling up the local filesystem.

151204/NISCC/IGNITE-UX/2
CVE ID: CAN-2004-0951

In certain circumstances when the make_recovery command is used, a copy of the /etc/passwd file
will be created in the TFTP server tree and made available for anonymous access.

However please note that as of version B.3.2 of the product, the make_recovery command has been
depreciated in preference for the make_tape_recovery command; also as of version C.6.0 of the
product, the make_recovery command does not exist at all. But please bear in mind that if at any
point the make_recovery command has been executed on the host, then a copy of the /etc/passwd file
may still exist within the TFTP server tree.

Mitigation
- ----------
To minimise the risk of these vulnerabilities, we suggest the following:

. If the TFTP server is not required, the please ensure that it is disabled.

. If the TFTP server is required, then please ensure that the TFTP server is not available
externally; as a general security practice, TFTP traffic should be blocked at the network gateway.

Solution
- --------
HP has made the following available to resolve the issue:
