PT-2009-23: Multiple Vulnerabilities Affected SoftwarePixelGems CMS Version XX and XXX Product Link: http://pixelgems.comSeverity RatingSeverity: High Impact: SQL Injection, Path Traversal, Cross-site Scripting Attack Vector: Remote CVSS v2Base Score: 7.5 Temporal Score: 5.9 Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P/E:P/RL:O/RC:C) CVE: not assignedSoftware DescriptionPixelGems CMS is a content management system (CMS) software, usually implemented as a Web application, for creating and managing HTML content. It is used to manage and control a large, dynamic collection of Web material (HTML documents and their associated images).Vulnerability DescriptionPositive Technologies Research Team has discovered the following vulnerabilities in PixelGems CMS:A) Multiple SQL Injection vulnerabitiesB) Path TraversalC) Multiple Cross-site Scripting vulnerabitiesA) SQL InjectionSQL injection is an attack technique that can be used to extract, modify, add or delete information from database servers that are used by vulnerable web applications. SQL injection vulnerabilities are caused by an unsecured programming technique that allows client-supplied data to interfere with the syntax of SQL queries. SQL is a programming language that is used by applications to communicate with database systems.User input passed to the "category", "start_pos" and "email" parameters is not properly sanitized. This can allows remote attackers to execute arbitrary SQL commands.Example (1): http://[server]/products.php?category=Footwear'SQL-code B) Path TraversalThe Path Traversal attack technique forces access to files, directories, and commands that potentially reside outside the web document root directory. An attacker may manipulate a URL in such a way that the web site will execute or reveal the contents of arbitrary files anywhere on the web server. Any device that exposes an HTTP-based interface is potentially vulnerable to Path Traversal.Example: http://[server]/filedownload.php?file=../../etc/passwd B) Multiple Cross-site Scripting vulnerabitiesUser input passed to the "category" and "submit" setting is not properly sanitized. This can be exploited to inject malicious code and allows to execute arbitrary HTML and script code in a user's browser session in context of an affected site.Example: http://[server]/products.php?category= Malicious users may inject JavaScript, VBScript, ActiveX, HTML or Flash into a vulnerable application to fool users in order to gather data from their machines. An attacker can steal the session cookie and take over the account impersonating the user. It is also possible to modify page content presented to the user.SolutionUpdate to latest version.Disclosure Timeline04/03/2009 - Vendor is notified 04/03/2009 - Vendor response 04/03/2009 - Requested status update from vendor XX/03/2009 - Vendor releases fixed version and details XX/03/2009 - Public disclosureCreditsThis vulnerability was discovered by Dmitry Evteev (Positive Technologies Research Team) using professional network security scanner MaxPatrol.Referenceshttp://en.securitylab.ru/lab/PT-2009-23 http://www.ptsecurity.ru/advisory.aspComplete list of vulnerability reports published by Positive Technologies Research Team:http://en.securitylab.ru/lab/ http://www.ptsecurity.ru/advisory.asp
