Date: 12 Jun 2009 19:13:15 -0000 From: security@...ern0t.net To: bugtraq@...urityfocus.com Subject: [InterN0T] Pivot 1.40.4-7 - Multiple Vulnerabilities Pivot - XSS and HTML Injection Vulnerabilities Versions Affected: 1.40.4 and 1.40.7 (22nd March 2009) (newest) Info: Pivot is a web-based tool to help you maintain dynamic sites, like weblogs or online journals. Pivot is released under the GPL so it is completely free to use. It is written in PHP, and does not require additional libraries or databases to function. Credits: InterN0T External Links: http://www.pivotlog.net/ -:: The Advisory ::- Vulnerable Function / ID Calls: url, menu, sort, check[], edituser, edit, blog, cat.

Affected Admin Site: http://[HOST]/pivot/pivot/index.php?session=VALIDSESSION&menu=admin&func=admin&do=editcommuser&edituser=VALIDUSERHASH -:: Solution ::- The solution for this is not simple at all. I suggest a complete review of the entire codebase. Conclusion: When we first checked the platform for vulnerabilities we had apparently installed an old version, so we updated to the newest version which apparently had some "XSS-bug fixed", strangely enough all the vulnerabilities we found are still there. Reference: http://forum.intern0t.net/intern0t-advisories/1119-intern0t-pivot-1-40-4-7-multiple-vulnerabilities.html Disclosure Information: - Vulnerabilities found, researched and confirmed between 5th to 10th June. - Advisory finished and published on InterN0T the 12th June. - Vendor and Buqtraq (SecurityFocus) contacted the 12th June. All of the best, MaXe
