Munin is an open source server monitoring tool.

When Munin is compiled with CGI graphics enabled then the files accessible to the www-data user can be overwritten.

A local attacker, by setting multiple upper_limit GET parameters, could overwrite files accessible to the www-user.

There is no known workaround at this time.

All Munin users should upgrade to the latest version:
