SGI Security Advisory
Title: iPlanet vulnerabilities
Number: 20020803-01-P
Date: August 1, 2002
Reference: CERT® Vulnerability Note #276767
Reference: CAN-2001-0327
_____________________________________________________________________________
- - -----------------------
- - --- Issue Specifics ---
- - -----------------------
Multiple vulnerabilities exist in the iPlanet Web Servers as supplied by SGI.
1) CERT has reported that a buffer overflow exists that may allow remote
attackers to gain read access to sensitive information contained in the
memory of the web server process. The information disclosed may include
userids, passwords, cookies or authentication data belonging to other users
of the web server. With this data the attacker may be able to falsely
authenticate themselves to the web server as other users. In some cases, the
attacker may be able to prevent the normal operation of the web server using
this vulnerability.
More information is available at the following URLs:
http://www.kb.cert.org/vuls/id/276767
http://www.atstake.com/research/advisories/2001/a041601-1.txt
2) The SNMP agent (magt) daemon supplied with the Admin Server component of
Netscape Directory Server 4.1x, iPlanet Directory Server 5.0, iPlanet
Directory Server 5.1, and iPlanet Web Proxy Server 3.6 on UNIX platforms is
vulnerable to a malformed request. The malformed request will cause the
"magt" daemon to abruptly exit, so that it will no longer accept requests.
More information is available at the following URLs:
http://knowledgebase.iplanet.com/ikb/kb/articles/7805.html
http://wwws.sun.com/software/download/patches/5174.html
3) There are also three additional vulnerabilities that exist in the
iPlanet Web Servers that are NOT addressed by this advisory. See the
"Impact" section.
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.
- - --------------
- - --- Impact ---
- - --------------
The iPlanet Webservers are an optional product and are not installed by
default on IRIX systems.
These vulnerabilities may be exploited by a remote user, and no local
account is required.
The exploitation of these vulnerabilities can lead to a root compromise.
These vulnerabilities have been reported by CERT and have been publicly
discussed in Usenet newsgroups and mailing lists.
The iPlanet webserver buffer overflow was assigned the following CVE:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2001-0327
See the following URLs for additional details on three vulnerabilities that
are not addressed by this patch or advisory, and iPlanet's suggested
workarounds:
1) wp-force-auth can be used in a brute force password cracking attack
http://knowledgebase.iplanet.com/ikb/kb/articles/7764.html
2) Unauthorized listing of directory contents via "?wp-" query
http://knowledgebase.iplanet.com/ikb/kb/articles/4302.html
3) The search functionality, not enabled by default, is vulnerable:

http://online.securityfocus.com/archive/1/281199/2002-07-07/2002-07-13/0
Steps to disable the Search function per iPlanet, is:

- - ----------------
- - --- Solution ---
- - ----------------
No patch is provided for magt iPlanet binary. Here are the steps to disable
the binary:
$ su -
# cd <server_root>/plugins/snmp/magt
(where server_root is the directory where iPlanet was installed)
# chmod -x magt
# killall magt
SGI has provided a patch that will fixes the iPlanet webserver buffer
overflow vulnerability reported by CERT.

NOTES
1) This version of the IRIX operating has been retired. Upgrade to an
actively supported IRIX operating system. See
http://support.sgi.com/irix/news/index.html#policy for more
information.
2) If you have not received an IRIX 6.5.X CD for IRIX 6.5, contact your
SGI Support Provider or URL: http://support.sgi.com/irix/swupdates/
3) It is important to read and follow the instructions in the Release
