DESCRIPTION:
d3b4g has reported two vulnerabilities in Venalsur Booking Centre,
which can be exploited by malicious people to conduct cross-site
scripting and SQL injection attacks.

1) Input passed to the "OfertaID" parameter in cadena_ofertas_ext.php
is not properly sanitised before being used in SQL queries. This can

code.

Successful exploitation of this vulnerability allows e.g. retrieval
of administrator usernames and passwords.
