====================================================================== Secunia Research 29/09/2006 - Joomla BSQ Sitestats Component Multiple Vulnerabilities - ====================================================================== Table of Contents Affected Software....................................................1 Severity.............................................................2 Vendor's Description of Software.....................................3 Description of Vulnerability.........................................4 Solution.............................................................5 Time Table...........................................................6 Credits..............................................................7 References...........................................................8 About Secunia........................................................9 Verification........................................................10 ====================================================================== 1) Affected Software BSQ Sitestats (component for Joomla) 1.x NOTE: Other versions may also be affected. ====================================================================== 2) Severity Rating: Highly critical Impact: System access Manipulation of data Cross Site Scripting Where: From remote ====================================================================== 3) Vendor's Description of Software "BSQ Sitestats is a site stats module that is lightweight on the front end but offers both tabular and graphical summaries of site visitors' sessions on the backend". Product Link: http://developer.joomla.org/sf/projects/bsq_sitestats ====================================================================== 4) Description of Vulnerability Secunia Research has discovered some vulnerabilities in the BSQ Sitestats component for Joomla, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks, and to compromise a vulnerable system. 1) Input passed to the "ip" form field parameter when performing an IP Address Lookup is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a logged in administrator's browser session in context of an affected site. 2) Input passed to multiple parameters when importing the ip-to-country.csv file is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code when an administrator is tricked into importing a malicious ip-to-country.csv file. 3) Input passed via the "HTTP Referer", the "HTTP User Agent", and the "HTTP Accept Language" Header bsqtemplateinc.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code. Successful exploitation requires that "magic_quotes_gpc" is disabled. 4) Input passed to the "baseDir" parameter in components/com_bsq_sitestats/external/rssfeeds.php is not properly verified before being used to include files. This can be exploited to execute arbitrary PHP code by including files from local or external resources. Successful exploitation requires that "register_globals" is enabled. The vulnerabilities have been confirmed in version 1.8.0. Other versions may also be affected. ====================================================================== 5) Solution The vulnerabilities have been fixed in version 2.2.1. ====================================================================== 6) Time Table 14/09/2006 - Vendor notified. 14/09/2006 - Vendor response. 17/09/2006 - Vendor releases fixed version 2.2.1. 29/09/2006 - Public disclosure. ====================================================================== 7) Credits Discovered by Sven Krewitt, Secunia Research. ====================================================================== 8) References None assigned. ====================================================================== 9) About Secunia Secunia offers vulnerability management solutions to corporate customers with verified and reliable vulnerability intelligence relevant to their specific system configuration: http://corporate.secunia.com/ Secunia also provides a publicly accessible and comprehensive advisory database as a service to the security community and private individuals, who are interested in or concerned about IT-security. http://secunia.com/ Secunia believes that it is important to support the community and to do active vulnerability research in order to aid improving the security and reliability of software in general: http://corporate.secunia.com/secunia_research/33/ Secunia regularly hires new skilled team members.
