Advisory Details:

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in epesi BIM which could be exploited to perform cross-site scripting attacks.


1) Cross-site scripting (XSS) vulnerabilities in epesi BIM

1.1 The vulnerability exists due to input sanitation error in the "dir_atual" parameters in admin/phpfm.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:
http://[host]/admin/phpfm.php?frame=3&dir_atual=%3Cscript%3Ealert%28123%29;%3C/script%3E

1.2 The vulnerability exists due to input sanitation error in URL parameter in admin/themeup.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:
http://[host]/admin/themeup.php/%22%3E%3Cscript%3Ealert%28123%29;%3C/script%3E

1.3 The vulnerability exists due to input sanitation error in the "msg" parameter in admin/wfb.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:
http://[host]/admin/wfb.php?msg=%3Cscript%3Ealert%28document.cookie%29;%3C/script%3E
