Description Jan Lieskovsky 2013-03-05 17:07:25 UTC
A security flaw was found in the way PHP performed soap.wsdl_cache_dir configuration directive validation before projecting SOAP WSDL cache content to the local filesystem. A remote attacker could use this flaw to place SOAP WSDL files at arbitrary file system locations (locations accessible with the privileges of the PHP application).

Comment 3 Vincent Danen 2013-03-07 17:25:38 UTC
Note that this is actually an open_basedir bypass issue.

The problem is that soap.wsdl_cache_dir does not consult the open_basedir directive to determine where it is allowed to write files.

Comment 4 Vincent Danen 2013-03-07 17:56:35 UTC

We do not consider safe_mode / open_basedir restriction bypass issues to be security sensitive.  For more details see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=169857#c1 and http://www.php.net/security-note.php
