Subversion is an advanced version control system, similar to CVS, which
|
|
|
|
|
supports additional functionality such as the ability to move, copy and
|
|
|
|
|
delete files and directories. A Subversion server may be run as an
|
|
|
|
|
Apache module, a standalone server (svnserve), or on-demand over ssh (a
|
|
|
|
|
la CVS' ":ext:" protocol). The mod_authz_svn Apache module works with
|
|
|
|
|
Subversion in Apache to limit access to parts of Subversion
|
|
|
|
|
repositories based on policy set by the administrator.

Users with write access to part of a Subversion repository may bypass
|
|
|
|
|
read restrictions on any part of that repository. This can be done
|
|
|
|
|
using an "svn copy" command to copy the portion of a repository the
|
|
|
|
|
user wishes to read into an area where they have write access.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|
|
|
|
|
Since copies are versioned, any such copy attempts will be readily
|
|
|
|
|
apparent.

This is a low-risk vulnerability. It affects only users of Subversion
|
|
|
|
|
who are running servers inside Apache and using mod_authz_svn.
|
|
|
|
|
Additionally, this vulnerability may be exploited only by users with
|
|
|
|
|
write access to some portion of a repository.

|
|
|
|
|
<workaround>
|
|
|
|
|
<p>
|
|
|
|
|
Keep sensitive content separated into different Subversion
|
|
|
|
|
repositories, or disable the Apache Subversion server and use svnserve
|
|
|
|
|
instead.
|
|
|
|
|
</p>

|
|
|
|
</workaround>
|
|
|
|
|
<resolution>
|
|
|
|
|
<p>
|
|
|
|
|
All Subversion users should upgrade to the latest available version:
