Description:
Some vulnerabilities have been discovered in Sisfo Kampus, which can be exploited by malicious people to gain knowledge of sensitive information or compromise a vulnerable system.

1) Input passed to the "slnt" parameter in index.php and print.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local or external resources.

2) Input passed to the "fn" parameter in downloadexcel.php and to the "f" parameter in dwoprn.php is not properly sanitised before being used to download files. This can be exploited to download arbitrary files via directory traversal attacks.

3) Input passed to the "nmf" parameter in blanko.preview.php is not properly verified before being used to read files. This can be exploited to read arbitrary files from local resources.

The vulnerabilities are confirmed in version 2006 (Semarang 3). Other versions may also be affected.

Solution:
Edit the source code to ensure that input is properly verified and sanitised.
