SGI Security Advisory
Title: IRIX hpsnmpd vulnerability
Number: 20020404-01-P
Date: April 24, 2002
Reference: CERT CA-2002-03
Reference: CVE CAN-2002-0012
Reference: CVE CAN-2002-0013
______________________________________________________________________________
- - -----------------------
- - --- Issue Specifics ---
- - -----------------------
It has been reported that the IRIX /usr/etc/hpsnmpd, when used with a public
read-only community, can be made to dump core when running the publicly
available "PROTOS Test-Suite: c06-snmpv1" regression tests, see:
http://www.ee.oulu.fi/research/ouspg/protos/testing/c06/snmpv1/
SGI is also investigating other non-base products that may have an SNMP
component.
SGI has investigated the issues and recommends the following steps for
neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be
implemented on ALL vulnerable SGI systems.
This will be corrected in a future release of the product.
- - --------------
- - --- Impact ---
- - --------------
The hpsnmp daemon is not installed by default, it is part of the
snmpd.sw.hp package and can be optionally installed.
In order to check to see if this package is installed, run the following
command:
# versions | grep snmpd.sw.hp
If the output of the above command looks like either of the following, then
the daemon is installed and the system is vulnerable:
I snmpd.sw.hp 03/14/2001 SNMP Sub-agent for HP-UX MIB 1.1.2
I snmpd.sw.hp 03/14/2001 SNMP Sub-agent for HP-UX MIB 1.1.3
If the installed version is 1.1.2, then you must first upgrade to version
1.1.3 and then you can install the patch.
If the installed version is older than 1.1.2, it won't work on IRIX 6.5 and
should be uninstalled.
These vulnerabilities may be exploited by a remote user, and no local
account is required.
This issue was reported on CERTŪ Advisory CA-2002-03 Multiple Vulnerabilities
in Many Implementations of the Simple Network Management Protocol (SNMP):
http://www.cert.org/advisories/CA-2002-03.html
The PROTOS vulnerability was assigned the following CVE:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0012
This PROTOS vulnerability was also assigned the following CVE:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2002-0013
- - ----------------------------
- - --- Temporary Workaround ---
- - ----------------------------
The only workaround for these problems is to uninstall the product using the
following commands:
# versions remove snmpd.sw.hp
SGI recommends installing patch 4544 according to the listing below.
- - ----------------
- - --- Solution ---
- - ----------------
SGI has provided a patch for these vulnerabilities. Our recommendation is to
install the appropriate patch.
