TITLE:
SGI IRIX arrayd Authentication Spoofing Vulnerability

SECUNIA ADVISORY ID:
SA15785

VERIFY ADVISORY:
http://secunia.com/advisories/15785/

CRITICAL:
Moderately critical

IMPACT:
Spoofing

WHERE:
>From local network

OPERATING SYSTEM:
SGI IRIX 6.5.x
http://secunia.com/product/132/

DESCRIPTION:
SGI has acknowledged a vulnerability in IRIX, which can be exploited
by malicious people to compromise a vulnerable system.

The vulnerability is caused due to an error in arrayd during the
processing of authentication requests when configured to use NONE or
SIMPLE authentication. This can be exploited to execute arbitrary
commands with root privileges on a vulnerable system.

Successful exploitation requires arrayd to be configured to use NONE
or SIMPLE authentication.

SOLUTION:
The vendor recommends that arrayd is configured to use NOREMOTE
authentication (default setting in IRIX 6.5.5 and later) until a
solution is available.
