Advisory Details:

High-Tech Bridge SA Security Research Lab has discovered three vulnerabilities in Scribe CMS which could be exploited to perform cross-site scripting attacks.

1) Cross-site scripting (XSS) vulnerability in Scribe CMS
1.1 The vulnerability exists due to input sanitation error in the “f” parameter in administrate_file.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 requires that victim is logged-in into the application and has access to administrative interface.
Exploitation example:
https://host/path/administrate_file.php?f=SITENAME%2F%00%22%3E%3Cscript%3Eal ert%28document.cookie%29 %3C/script%3E&fn=view
1.2 The vulnerability exists due to input sanitation error in the "orig_t_id" parameter in template_admin.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 requires that victim is logged-in into the application and has access to administrative interface.
Exploitation example:
https://host/path/template_admin.php?action=t_edit&orig_t_id=./%3Cscript%3Ea lert%28document.cookie%2 9%3C/script%3E&path=SITENAME
1.3 The vulnerability exists due to input sanitation error in the "path" parameter in copy_folder.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 requires that victim is logged-in into the application and has access to administrative interface.
Exploitation example:
https://host/path/copy_folder.php?path=SITE/%3Cscript%3Ealert%28document.coo kie%29%3C/script%3E
