DESCRIPTION:
K-sPecial has reported some vulnerabilities in iShopCart, which can
be exploited by malicious people to disclose potentially sensitive
information and compromise a vulnerable system.

1) A boundary error in the "vGetPost()" function when handling POST
requests can be exploited to cause a stack-based buffer overflow and
may allow arbitrary code execution.

2) A boundary error within the handling of the parameter string
received via a GET request can be exploited to cause a stack-based
buffer overflow and may allow arbitrary code execution.

3) An input validation error within the handling of filenames
received via GET requests can be exploited to disclose arbitrary
files accessible by the web server process via directory traversal
attacks.

SOLUTION:
The vulnerabilities will reportedly be fixed soon.

Filter malicious characters and character sequences in a proxy or
firewall with a URL filtering capabilities.
