-----BEGIN PGP SIGNED MESSAGE----- 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.
