trueend5 has discovered some vulnerabilities in PHP-Post, which can be exploited by malicious people to conduct cross-site scripting and script insertion attacks.
1) Input passed to the "user" parameter in "profile.php" and "mail.php" isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Input passed to the "subject" field when sending a post isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious subject is viewed.
The vulnerabilities have been confirmed in version 1.0. Other versions may also be affected.
Solution: Edit the source code to ensure that input is properly sanitised.
