Description

This module exploits a vulnerability in the 'proc_deutf()' function
defined in /includes/functions_vbseocp_abstract.php for vBSEO versions
3.6.0 and earlier. User input passed through 'char_repl' POST parameter
isn't properly sanitized before being used in a call to preg_replace()
function which uses the 'e' modifier. This can be exploited to inject
and execute arbitrary code leveraging the PHP's complex curly syntax.
