Subject: Corsaire Security Advisory: HP Ignite-UX filesystem permissions issue

-- Corsaire Security Advisory --

Title: HP Ignite-UX filesystem permissions issue
Date: 23.11.04
Application: HP Ignite-UX prior to version C.6.2.241
Environment: HP-UX
Author: Martin O'Neal [martin.oneal@...saire.com]
Audience: General distribution
Reference: c041123-002

-- Scope --

The aim of this document is to clearly define a vulnerability in the HP
Ignite-UX product, as supplied by HP Inc. [1], that would allow
unauthenticated write access to the host filesystem, both remotely and
locally.

-- History --

Discovered: 23.11.04 (Martin O'Neal)
Vendor notified: 23.11.04
Document released: 16.08.05

-- Overview --

The HP Ignite-UX "addresses the need for HP-UX system administrators to
perform system installations and deployment, often on a large scale" [2]

As part of the installation process, the product can install and enable
a TFTP server to facilitate anonymous access to configuration data. In
certain circumstances, sections of the TFTP server tree can become
world-writeable, allowing an attacker to use this as a mechanism for
moving data/tools into and out of the host, or simply launch a DoS
exhaustion attack against the host through filling the local filesystem.

-- Analysis --

The HP Ignite-UX can use a TFTP server to facilitate anonymous access to
configuration data. When the add_new_client command is used, sections of
the TFTP server tree may be made world-writeable.

-- Recommendations --

Download and apply the HP Ignite-UX version C.6.2.241 patches.

If in any doubt, disable the TFTP server.

-- CVE --

The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CAN-2004- 0952 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org), which standardises names for
security problems.
