-- 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.
