DESCRIPTION:
Some vulnerabilities have been discovered in YouTube Blog, which can
be exploited by malicious people to conduct cross-site scripting and
SQL injection attacks, disclose sensitive information, and compromise
a vulnerable system.

1) Input passed to the "id" parameter in todos.php is not properly
sanitised before being used in SQL queries. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "m" parameter in mensaje.php 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) Input passed to the "base_archivo" parameter in cuenta/cuerpo.php
is not properly verified before being used to include files. This can
be exploited to include arbitrary files from local or external
resources.

Successful exploitation of this vulnerability requires that
"register_globals" is enabled.

4) Input passed to the "id" parameter in info.php is not properly
sanitised before being used in SQL queries. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities are confirmed in version 0.1. Other versions may
also be affected.

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