DESCRIPTION:
Preddy has reported two vulnerabilities in Online Universal Payment
System Script, which can be exploited by malicious people to conduct
cross-site scripting attacks and disclose sensitive information.

1) Input passed to the "read" parameter in "index.php" isn't properly
sanitised before being used to view files. This can be exploited to
disclose the content of arbitrary files via directory traversal
attacks.

2) Input passed to the "read" parameter in "index.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.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
