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.
