An attacker can read files using either the doc-as-string() extension function or a XML External Entity attack. Write access is done via the <exsl:document> extension element. Depending of your policy, you may want to affect one, two or three CVE (one by vector ? by impact ? by type of bug ?). > Does everything using 4Suite have this issue? Yes. Unless an obscure and undocumented option allows to deactivate this behavior :-( My XSLT Wiki has some additional details, including PoC code : - http://goo.gl/3A7h2 (4Suite) - http://goo.gl/GI5NK (MoinMoin) Regards, Nicolas
