==[ DETAILS
===========
Many vulnerabilities have been discovered in Membrepass v1.5.

1)Input passed to the "recherche" parameter in /recherchemembre.php isn't
properly sanitised before being used in a SQL query. This bug can be
exploited to conduct SQL injection attacks. Successful exploitation may
require that "magic_quotes_gpc" is disabled.

2)Input passed to the "aifon" parameter in /include/change.php isn't
properly satanised before being used in fputs() function. This can
be exploited to execude PHP code. Successful exploitation may require
that "register_globals" is enabled and "magic_quotes_gpc" is disabled.

3)Input passed to the "recherche" parameter in /recherchemembre.php and
to the "email" parameter in /test.php isn't properly satanised before
being returned to the user. This can be exploited to conduct cross-site
scripting attacks. Successful exploitation may require that
"register_globals" is enabled.
