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:

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
