CERT Advisory CA-2003-11 Multiple Vulnerabilities in Lotus Notes and Domino

Original release date: March 26, 2003
Last revised: --
Source: CERT/CC

A complete revision history can be found at the end of this file.

Systems Affected

* Lotus Notes and Domino versions prior to 5.0.12 and 6.0 Gold
* VU#571297 affects 5.0.12, 6.0.1 and prior versions.

Overview

Multiple vulnerabilities have been reported to affect Lotus Notes
clients and Domino servers. Multiple reporters, the close timing, and
some ambiguity caused confusion about what releases are vulnerable. We
are issuing this advisory to help clarify the details of the
vulnerabilities, the versions affected, and the patches that resolve
these issues.

I. Description

In February 2003, NGS Software released several advisories detailing
vulnerabilities affecting Lotus Notes and Domino. The following
vulnerabilities reported by NGS Software affect versions of Lotus
Domino prior to 5.0.12 and 6.0:

VU#206361 - Lotus iNotes vulnerable to buffer overflow via
PresetFields FolderName field
Lotus Technical Documentation: KSPR5HUQ59
NGS Software's Advisory: NISR17022003b

VU#355169 - Lotus Domino Web Server vulnerable to denial of service
via incomplete POST request
Lotus Technical Documentation: KSPR5HTQHS
NGS Software's Advisory: NISR17022003d

VU#542873 - Lotus iNotes vulnerable to buffer overflow via
PresetFields s_ViewName field
Lotus Technical Documentation: KSPR5HUPEK
NGS Software's Advisory: NISR17022003b

VU#772817 - Lotus Domino Web Server vulnerable to buffer overflow
via non-existent "h_SetReturnURL" parameter with an overly long
"Host Header" field
Lotus Technical Documentation: KSPR5HTLW6
NGS Software's Advisory: NISR17022003a

The following vulnerability reported by NGS Software affects versions
of Lotus Domino up to and including 5.0.12 and 6.0.1:

VU#571297 - Lotus Notes and Domino COM Object Control Handler
contains buffer overflow
Lotus Technical Documentation: SWG21104543
NGS Software's Advisory: NISR17022003e

VU#571297 was originally reported as a vulnerability in an iNotes
ActiveX control. The vulnerable code is not specific to iNotes or
ActiveX. The iNotes ActiveX control was an attack vector for the
vulnerability and is not the affected code base. Because this issue is
not specific to ActiveX, Lotus Notes clients and Domino Servers
running on platforms other than Microsoft Windows may be affected.

In March 2003, Rapid7, Inc. released several advisories. The following
vulnerabilities, reported by Rapid7, Inc., affect versions of Lotus
Domino prior to 5.0.12:

VU#433489 - Lotus Domino Server susceptible to a pre-authentication
buffer overflow during Notes authentication
Lotus Technical Documentation: DBAR5CJJJS
Rapid7, Inc.'s Advisory: R7-0010

VU#411489 - Lotus Domino Web Retriever contains a buffer overflow
vulnerability
Lotus Technical Documentation: KSPR5DFJTR
Rapid7, Inc.'s Advisory: R7-0011

Rapid7, Inc. also discovered that Lotus Domino pre-release and beta
versions of 6.0 were also affected by the following vulnerability:

VU#583184 - Lotus Domino R5 Server Family contains multiple
vulnerabilities in LDAP handling code
Lotus Technical Documentation: DWUU4W6NC8
Rapid7, Inc.'s Advisory: R7-0012

VU#583184 was a regression of the PROTOS LDAP Test-Suite from
CA-2001-18 and was originally fixed in 5.0.7a.

II. Impact

The impact of these vulnerabilities range from denial of service to
data corruption and the potential to execute arbitrary code. For
details about the impact of a specific vulnerability, please see the
related vulnerability note.

III. Solution

Upgrade

Most of these vulnerabilities are resolved in versions 5.0.12 and
6.0.1 of Lotus Domino.

Only VU#571297, "Lotus Notes and Domino COM Object Control Handler
contains buffer overflow," is not resolved in 5.0.12, or 6.0.1.
Critical Fix 1 for 6.0.1 was released on March 18, 2003, to resolve
this issue for both the Notes client and Domino server.

Apply a patch

Patches are available for some vulnerabilities. Please view the
individual vulnerability notes for specific patch information.

Block access from outside the network perimeter

Lotus Domino servers listen on port 1352/TCP. Notes may also be
configured to listen on other ports, such as NETBIOS, SPX, or XPC.
Blocking access to these ports from machines outside your trusted
network perimeter may help mitigate successful exploitation of these
vulnerabilities.
