Vulnerability Assessment Details

[GLSA-200407-20] Subversion: Vulnerability in mod_authz_svn

Vulnerability Assessment Summary
Subversion: Vulnerability in mod_authz_svn

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200407-20
(Subversion: Vulnerability in mod_authz_svn)

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.
Since copies are versioned, any such copy attempts will be readily
apparent.

Impact

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

Keep sensitive content separated into different Subversion repositories, or
disable the Apache Subversion server and use svnserve instead.
