PLATFORM: Debian GNU/Linux 3.0 (woody) Red Hat Desktop (v. 3 & v. 4) Red Hat Enterprise Linux AS, ES, WS (v.2.1, v.3 & v.4) Red Hat Linux Advanced Workstation 2.1 for the Itanium Processor SGI Advanced Linux Environment 3, SGI ProPack 3 Service Pack 4 DAMAGE: There is a cross-site scripting vulnerability in mailman's automatically generated error messages (assigned CAN-2004-1177). A vulnerability that allows unauthorized access to archives of private lists and the list configuration itself, including the users passwords also exists (assigned CAN-2005-0202). This seems to affect installations running on web servers that do not strip slashes, such as Apache 1.3. SOLUTION: Apply the available security update. ______________________________________________________________________________ VULNERABILITY The risk is LOW. If exploited the cross-site scripting ASSESSMENT: vulnerability may lead to an attacker gaining access to a victim's mailman account. The directory traversal vulnerability may allow an attacker access to archives of private lists and the list configuration itself. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/p-137.shtml ORIGINAL BULLETIN: http://www.debian.org/security/2005/dsa-674 ADDITIONAL LINK: Red Hat Security Advisory RHSA-2005:136-08 https://rhn.redhat.com/errata/RHSA-2005-136.html Red Hat Security Advisory RHSA-2005:137-07 https://rhn.redhat.com/errata/RHSA-2005-137.html SGI Security Advisory 20050207-01-U Security Update #27 http://www.sgi.com/support/security/advisories.html Red Hat Security Advisory RHSA-2005:235-05 https://rhn.redhat.com/errata/RHSA-2005-235.html SGI Security Advisory 20050303-01-U Security Update #31 http://www.sgi.com/support/security/advisories.html CVE/CAN: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CAN-2004-1177, CAN-2005-0202 ______________________________________________________________________________ REVISION HISTORY: 02/11/2005 - revised to reflect the changes Debian has made to DSA-674-1. 02/22/2005 - added link to Red Hat Security Advisory RHSA-2005:137 that provides updated packages for Red Hat version 4. 03/07/2005 - replaced the Debian Security Advisory DSA-674 with a revised bulletin, DSA-674-3. 03/11/2005 - revised to add a link to SGI Security Advisory 20050207-01-U SGI Advanced Linux Environment 3 Security Update #27 for Patch 10144 for SGI ProPack 3 Service Pack 4. 03/23/2005 - revised to add a link to Red Hat RHSA-2005:235-05. 04/05/2005 - revised to add a link to SGI Security Advisory Update #31, patch 10152 for SGI ProPack 3 Service Pack 4. [***** Start Debian Security Advisory DSA 674-3 *****] Debian Security Advisory DSA-674-3 mailman -- cross-site scripting, directory traversal Date Reported: 21 Feb 2005 Affected Packages: mailman Vulnerable: Yes Security database references: In Mitre's CVE dictionary: CAN-2004-1177, CAN-2005-0202. More information: Due to an incompatibility between Python 1.5 and 2.1 the last mailman update did not run with Python 1.5 anymore. This problem is corrected with this update. This advisory only updates the packages updated with DSA 674-2. The version in unstable is not affected since it is not supposed to work with Python 1.5 anymore. For completeness below is the original advisory text: Two security related problems have been discovered in mailman, web-based GNU mailing list manager. The Common Vulnerabilities and Exposures project identifies the following problems: CAN-2004-1177 Florian Weimer discovered a cross-site scripting vulnerability in mailman's automatically generated error messages. An attacker could craft an URL containing JavaScript (or other content embedded into HTML) which triggered a mailman error page that would include the malicious code verbatim. CAN-2005-0202 Several listmasters have noticed unauthorised access to archives of private lists and the list configuration itself, including the users passwords. Administrators are advised to check the webserver logfiles for requests that contain "/...../" and the path to the archives or configuration. This does only seem to affect installations running on web servers that do not strip slashes, such as Apache 1.3. For the stable distribution (woody) these problems have been fixed in version 2.0.11-1woody11. For the unstable distribution (sid) these problems have been fixed in version 2.1.5-6. We recommend that you upgrade your mailman package.
