<title>thttpd: Unauthenticated remote file access</title>
|
|
<synopsis>
|
|
The default configuration of the Gentoo thttpd package potentially allows
|
|
unauthenticated access to system files when used with newer versions of
|
|
baselayout.

|
|
thttpd is vulnerable to an underlying change made to the
|
|
start-stop-daemon command in the current stable Gentoo baselayout
|
|
package (version 1.12.6). In the new version, the start-stop-daemon
|
|
command performs a "chdir /" command just before starting the thttpd
|
|
process. In the Gentoo default configuration, this causes thttpd to
|
|
start with the document root set to "/", the sytem root directory.
|
|
</p>
|
|
</description>
|
|
<impact type="low">
|
|
<p>
|
|
When thttpd starts with the document root set to the system root
|
|
directory, all files on the system that are readable by the thttpd
|
|
process can be remotely accessed by unauthenticated users.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Alter the THTTPD_OPTS variable in /etc/conf.d/thttpd to include the
|
|
"-d" option to specify the document root. Alternatively, modify the
|
|
THTTPD_OPTS variable in /etc/conf.d/thttpd to specify a thttpd.conf
|
|
file using the "-C" option, and then configure the "dir=" directive in
|
|
that thttpd.conf file.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All thttpd users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-servers/thttpd-2.25b-r5"</code>
