http://security.gentoo.org/

Severity:	high
Title:	Tikiwiki: Arbitrary command execution
Date:	09/26/2006
Bugs:	#145714
ID:	200609-16

Synopsis

Tikiwiki contains a cross-site scripting (XSS) vulnerability as well as a second vulnerability which may allow remote execution of arbitrary code.

Background

Tikiwiki is a web-based groupware and content management system, developed with PHP, ADOdb and Smarty.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-apps/tikiwiki	< 1.9.5	>= 1.9.5	All supported architectures

Description

A vulnerability in jhot.php allows for an unrestricted file upload to the img/wiki/ directory. Additionally, an XSS exists in the highlight parameter of tiki-searchindex.php.

Impact

An attacker could execute arbitrary code with the rights of the user running the web server by uploading a file and executing it via a filepath parameter. The XSS could be exploited to inject and execute malicious script code or to steal cookie-based authentication credentials, potentially compromising the victim's browser.

Workaround

There is no known workaround at this time.

Resolution

All Tikiwiki users should upgrade to the latest version:

    # emerge --sync
    # emerge --oneshot --verbose --ask ">=www-apps/tikiwiki-1.9.5"
