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.

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.
