HEWLETT-PACKARD SECURITY ADVISORY: HPSBU0796-035, 22 July 1996
- -------------------------------------------------------------------------
The information in the following Security Advisory should be acted upon
as soon as possible. Hewlett Packard will not be liable for any
consequences to any customer resulting from customer's failure to fully
implement instructions in this Security Advisory as soon as possible.
- -------------------------------------------------------------------------
PROBLEM: Incorrect permissions on nettune executable
PLATFORM: HP 9000/700 and 9000/800 systems running operating system
version 10.0 or 10.01 of HP-UX.
DAMAGE: The configuration of various networking parameters could be
modified by non-root users.
SOLUTION: Login as root user and issue the following commands:
chmod 555 /usr/contrib/bin/nettune
chown bin /usr/contrib/bin/nettune
AVAILABILITY: Not applicable
- -------------------------------------------------------------------------
I. Nettune
A. Background
The nettune program is a utility program that allows non-root
users to examine and root users to modify several items that
affect networking. The nettune binary that ships with HP-UX
10.0 and 10.01 has incorrect permission attributes that allow
non-root users to modify networking parameters which only root
users should be able to modify. Operating systems released
after 10.01, such as HP-UX 10.10, correctly set the permissions
on this program file and are therefore not vulnerable.
B. Fixing the problem
The fix for this problem is to modify the owner and execution
permissions of the nettune binary itself. This can easily be
accomplished using the chown and chmod commands listed below.
C. Recommended solution
Login as root user and issue the following commands:
chmod 555 /usr/contrib/bin/nettune
chown bin /usr/contrib/bin/nettune
D. To subscribe to automatically receive future NEW HP Security

Description: Security Vulnerability in SAM remote admin
===============================================================================
- -----------------------------------------------------------------------
HEWLETT-PACKARD SECURITY BULLETIN: #HPSBUX9607-034, 22 July 1996
- -----------------------------------------------------------------------
The information in the following Security Bulletin should be acted upon
as soon as possible. Hewlett Packard will not be liable for any
consequences to any customer resulting from customer's failure to fully
implement instructions in this Security Bulletin as soon as possible.
- -----------------------------------------------------------------------
PROBLEM: Vulnerabilities in SAM remote administration.
PLATFORM: HP 9000/300/400/700 and 800 systems running any currently
supported version of HP-UX 9.X and 10.X.
DAMAGE: The security of the enterprise and its applications could
be compromised.
SOLUTION: Follow the procedure below.
AVAILABILITY: Not applicable
- -----------------------------------------------------------------------
I. Mailing list discussions
A. Background
It has recently come to the attention of Hewlett-Packard that
remote administration of cluster nodes via SAM (System
Administration Manager) is done with a now widely known
password. There is a default account password used in the
currently shipping SAM binary. That user gets created via rsh
on the remote machine.
B. Recommended workaround
Hewlett-Packard strongly recommends that administrators concerned
with the security of their enterprise either:
a) do not configure remote administration, or
b) replace that existing password field in /etc/passwd with an
asterisk (*)
Hewlett-Packard is working to deliver new scheme in a future
release of the SAM product.
