Advisory Details:
High-Tech Bridge SA Security Research Lab has discovered vulnerabilities in ZENphoto which could be exploited to perform cross-site scripting attacks and disclose potentially sensitive information. 1) Cross-site scripting (XSS) vulnerability in ZENphoto The vulnerability exists due to input sanitation error in the "_zp_themeroot" parameter in themes/zenpage/slideshow.php and themes/stopdesign/comment_form.php. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website. Successful exploitation of the vulnerabilities requires that "register globals" is enabled. Exploitation examples: http://[host]/themes/zenpage/slideshow.php?_zp_themeroot=%22%3E%3Cscript%3Ea lert%28%22XSS%22%29;%3Cs cript%3E http://[host]/themes/stopdesign/comment_form.php?_zp_themeroot=%22 %3E%3Cscript%3Ealert%28% 22XSS22%29;%3C/script%3E 2) Installation path disclosure weakness in ZENphoto The weakness exists due to application reveals the full path to installation directory in an error message. A remote attacker can directly access scripts inside the themes/effervescence_plus/ and /themes/default/ directories and gain knowledge of the web root directory and other potentially sensitive information. Exploitation examples: http://[host]/themes/default/slideshow.php http://[host]/themes/default/pas sword_form.php http://[ host]/themes/effervescence_plus/404.php http://[host]/themes/effervescence_ plus/archive.php http:/ /[host]/themes/effervescence_plus/gallery.php http://[host]/themes/efferves cence_plus/index.php ht tp://[host]/themes/effervescence_plus/image.php
