Title: Proxomitron Cross-Site Scripting Vulnerability
Severity: HIGH
Description:
Proxomitron is a free web-privacy application, offering support for filtering of content and connection to various types of proxy.
Proxomitron does not protect against cross-site scripting attacks.
When it cannot retrieve a web document, Proxomitron outputs an error webpage. The URL that it attempted to use is displayed without being sanitized. It is possible for attackers to construct urls that will cause scripting code to be embedded in the error page. When the client interprets the error page, the attacker-supplied code may execute within the context of the proxy server.
This type of vulnerability may be used to steal cookies or perform other web-based attacks.
