Corsaire Security Advisory - The aim of this document is to clearly define a vulnerability in the HP Ignite-UX product, as supplied by HP Inc., that would allow unauthenticated access to a copy of the /etc/passwd file.

-- Corsaire Security Advisory --

Title: HP Ignite-UX passwd file disclosure 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@corsaire.com]
Audience: General distribution
Reference: c041123-001


-- 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 access to a copy of the /etc/passwd file.


-- History --

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


-- Overview --

The HP Ignite-UX application "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, a copy of the /etc/passwd file will be moved into
the TFTP server tree and made available for anonymous access.


-- Analysis --

The HP Ignite-UX can use a TFTP server to facilitate anonymous access to
configuration data. 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.

As of version B.3.2 of the product, the make_recovery command has been
depreciated in preference for the make_tape_recovery command (which
doesn't display the same issues), and as of version C.6.0 the
make_recovery command does not exist in the product at all. However, if
at any point make_recovery has been run on the host, a copy of the
/etc/passwd file may still remain within the TFTP server tree.


-- Proof of Concept -

Use a TFTP client to request the file referenced by the following path:

       /var/opt/ignite/recovery/passwd.makrec


-- Recommendations --

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

Replace all usage of the make_recovery command with make_tape_recovery.

If in any doubt, disable the TFTP server.


-- CVE --

The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CAN-2004- 0951 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org), which standardises names for
security problems.

HP-UX Ignite-UX TFTP Service make_recovery Remote passwd File Disclosure
Remote / Network Access Misconfiguration
Loss of Integrity
Exploit Public

- 漏洞描述

HP UX's Ignite-UX contains a flaw that may lead to an unauthorized password exposure. It is possible to gain access to the /etc/passwd if the make_recovery command has been run by the administrator. The make_recovery utility copies /etc/passwd to the TFTP anonymous directories, which may lead to a loss of confidentiality.
