TITLE:
Siestta Cross-Site Scripting and Local File Inclusion Vulnerabilities

SECUNIA ADVISORY ID:
SA39453

VERIFY ADVISORY:
http://secunia.com/advisories/39453/

DESCRIPTION:
Some vulnerabilities have been discovered in Siestta, which can be
exploited by malicious people to conduct cross-site scripting attacks
and disclose sensitive information.

1) Input passed to the "usuario" parameter in carga_foto_al.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.

2) Input passed to the "idioma" parameter in login.php is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local resources via
directory traversal sequences.

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities are confirmed in version 2.0. Other versions may
also be affected.

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