DESCRIPTION:
Lincoln has discovered two vulnerabilities and a security issue in
123 Flash Chat, which can be exploited by malicious people to
disclose sensitive information and conduct cross-site scripting
attacks.

1) Input passed via the URL is not properly verified before being
used to read files. This can be exploited to disclose the contents of
arbitrary files via directory traversal attacks.

2) Input passed via the URL is not 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.

3) A security issue is caused due to the user name and the password
being transmitted via a web request in clear text when logging in to
the chat server.

NOTE: Additionally, a weakness exists due to the Flash cross-domain
policy (crossdomain.xml) allowing access from arbitrary domains.

The vulnerabilities and the security issue are confirmed in version
7.8. Other versions may also be affected.

SOLUTION:
Filter malicious characters and character sequences in a proxy. Use
HTTPS on the chat server. Vulnerabilities #1 and #2 are fixed in
version 8.0.

PROVIDED AND/OR DISCOVERED BY:
Lincoln
