-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0441 -- [Solaris] Cross Site Scripting (XSS) Vulnerabilities in the Apache 1.3 and 2.0 "mod_imap" and "mod_status" Modules 7 May 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Apache 2.0 Apache 1.3 Publisher: Sun Microsystems Operating System: Solaris Impact: Cross-site Scripting Access: Remote/Unauthenticated CVE Names: CVE-2007-6388 CVE-2007-5000 Ref: ESB-2008.0074 ESB-2008.0056 Original Bulletin: http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-66-233623-1 Revision History: May 7 2008: Resolution provided by Sun April 30 2008: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- Solution Type: Sun Alert Solution 233623 : Cross Site Scripting (XSS) Vulnerabilities in the Apache 1.3 and 2.0 "mod_imap" and "mod_status" Modules Bug ID: 6644748, 6644749 Product Solaris 8 Operating System, Solaris 9 Operating System, Solaris 10 Operating System Date of Workaround Release: 28-Feb-2008 Date of Resolved Release: 05-May-2008 SA Document Body Cross Site Scripting (XSS) Vulnerabilities in the Apache 1.3 and 2.0 "mod_imap" and "mod_status" Modules 1. Impact Two security vulnerabilities have been found in the Apache HTTP server which affect the Apache 2.0 web server bundled with Solaris 10 and the Apache 1.3 web server bundled with Solaris 8, Solaris 9 and Solaris 10. The first issue, a Cross Site Scripting (CSS or XSS) vulnerability in the "mod_imap" Apache server module (CVE-2007-5000), may allow a local or remote unprivileged user to inject arbitrary web script or HTML. This may allow the unprivileged user to bypass access control and gain access to unauthorized data. The second issue, a Cross Site Scripting (CSS or XSS) vulnerability in the "mod_status" Apache server module (CVE-2007-6388), may allow a local or remote unprivileged user to inject arbitrary web script or HTML. This may allow the unprivileged user to bypass access control and gain access to unauthorized data. Additional information regarding these issues is available at: The Change Log for Apache 2.0 at http://www.apache.org/dist/httpd/CHANGES_2.0 The Change Log for Apache 1.3 at http://www.apache.org/dist/httpd/CHANGES_1.3 CVE-2007-5000 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5000 CVE-2007-6388 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6388 2. Contributing Factors These issues can occur in the following releases: SPARC Platform * Solaris 8 without patch 116973-07 * Solaris 9 without patch 113146-10 * Solaris 10 without patch 120543-11 and without patch 122911-11 x86 Platform * Solaris 8 without patch 116974-07 * Solaris 9 without patch 114145-09 * Solaris 10 without patch 120544-11 and without patch 122912-11 Note 1: A system is only vulnerable to the described issues if the Apache 1.3 web server and/or Apache 2.0 web server has been configured and is running on the system. The following command can be run to determine if the Apache 1.3 web server is currently running on the system: $ /usr/bin/ps -ef | grep httpd nobody 103892 102307 0 Jan 20 ? 0:27 /usr/apache/bin/httpd The following SMF (smf(5)) command can be used to see if the Solaris 10 bundled Apache 2 web server service is enabled: $ svcs svc:/network/http:apache2 STATE STIME FMRI\ disabled Feb_02 svc:/network/http:apache2 Note 2: The mod_imap vulnerability (CVE-2007-5000) only affects systems which make use of the Apache Server Status module mod_imap. To determine if this module is enabled, a command such as the following can be run for all of the configuration files that define the running Apache 1.3 and Apache 2 configuration: $ egrep "imap-file|application/x-httpd-imap" /etc/apache/httpd.conf | grep map AddType application/x-httpd-imap map $ egrep "imap-file|application/x-httpd-imap" /etc/apache2/httpd.conf | grep map AddHandler imap file map Note 3: The mod_status vulnerability (CVE-2007-6388) only affects systems which make use of the Apache Server Status module (mod_status). To determine if this module is enabled, a command such as the following can be run for all of the configuration files that define the running Apache 1.3 and Apache 2 configuration: $ grep SetHandler /etc/apache/httpd.conf | grep server-status SetHandler server-status $ grep SetHandler /etc/apache2/httpd.conf | grep server-status SetHandler server-status 3. Symptoms There are no predictable symptoms that would indicate the described issues have been exploited on a system. 4. Workaround To avoid the mod_imap issue (CVE-2007-5000) from occurring, make sure that there is no activation of map files (see Note 2 in Section 2) in the Apache httpd.conf file. To avoid the mod_status issue (CVE-2007-6388) from occurring, make sure that the "ExtendedStatus" entry in the Apache httpd.conf file is disabled. 5. Resolution This issue is addressed in the following releases: SPARC Platform * Solaris 8 with patch 116973-07 or later * Solaris 9 with patch 113146-10 or later * Solaris 10 with patch 120543-11 or later and patch 122911-11 or later x86 Platform * Solaris 8 with patch 116974-07 or later * Solaris 9 with patch 114145-09 or later * Solaris 10 with patch 120544-11 or later and patch 122912-11 or later For more information on Security Sun Alerts, see Technical Instruction ID 213557.
