   Bug ID: 6602661, 6602665

   Date of Workaround Release: 21-DEC-2007

   Date of Resolved Release: 15-Feb-2008

   SA Document Body
Two security vulnerabilities exist in the Apache HTTP server which may affect t
he Apache 2.0 web server (see below for details)

   1. Impact

   Two security vulnerabilities exist in the Apache HTTP server which may
   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_status" Apache server module (CVE-2006-5752), may allow a
   local or remote unprivileged user to inject arbitrary web script or
   HTML. This may allow an unprivileged user to bypass access control and
   gain access to unauthorized data.

   The second issue, a vulnerability in the Apache HTTP server daemon
   (CVE-2007-3304), may allow a local user to send signals to
   an arbitrary process resulting in a Denial of Service (DoS).

   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-2006-5752 at:
     * http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5752

   CVE-2007-3304 at:
     * http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3304

   2. Contributing Factors

   These issues can occur in the following releases:

   SPARC Platform
     * Solaris 8 without patch 116973-06
     * Solaris 9 without patch 113146-09
     * Solaris 10 without patches 120543-10 and 122911-08

   x86 Platform
     * Solaris 8 without patch 116974-06
     * Solaris 9 without patch 114145-08
     * Solaris 10 without patches 120544-10 and 122912-08

   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.

   To determine if the Apache 1.3 web server is currently running on the
   system, the following command can be used:
    $ /usr/bin/ps -ef | grep httpd
    nobody 103892 102307 0 Jan 20 ? 0:27 /usr/apache/bin/httpd

   To determine if the Solaris 10 bundled Apache 2 web server service is
   enabled, the following SMF command can be used:
    $ svcs svc:/network/http:apache2
    STATE          STIME    FMRI
    disabled       Feb_02   svc:/network/http:apache2

   The "mod_status" vulnerability (CVE-2006-5752) only affects systems
   which make use of the Apache Server Status module (mod_status) and the
   option "ExtendedStatus" is enabled.

   To determine if a system is using the Apache Server Status module
   (mod_status), the following command 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

   To determine if the option "ExtendedStatus" is enabled, the following
   command can be run for all of the configuration files that define the
   running Apache 1.3 and Apache 2 configuration:
    $ grep ExtendedStatus /etc/apache/httpd.conf
    ExtendedStatus On

    $ grep ExtendedStatus /etc/apache2/httpd.conf
    ExtendedStatus On

   3. Symptoms

   There are no predictable symptoms that would indicate the described
   issues have been exploited on a system.
   4. Workaround

   To work around the "mod_status issue" (CVE-2006-5752), disable the
   "ExtendedStatus" entry in the Apache "httpd.conf" file.

   There is no workaround for the Apache Web Server daemon issue
   (CVE-2007-3304).
   5. Resolution

   These issues are addressed in the following releases:

   SPARC Platform
     * Solaris 8 with patch 116973-06 or later
     * Solaris 9 with patch 113146-09 or later
     * Solaris 10 with patches 120543-10 and 122911-08 or later

   x86 Platform
     * Solaris 8 with patch 116974-06 or later
     * Solaris 9 with patch 114145-08 or later
     * Solaris 10 with patches 120544-10 and 122912-08 or later
