Lepszy BIP is vulnerable to Reflected Cross-Site Scripting (XSS). Improper input validation in index.php form in one of the parameters allows arbitrary JavaScript to be executed on victim's browser when specially crafted URL is opened. The vendor was contacted early about this disclosure but did not respond in any way. Potentially all versions are vulnerable.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
