Severity: high

Date: October 20, 2007
Bug(s): #195503

Synopsis

Tikiwiki contains a command injection vulnerability which may allow remote execution of arbitrary code.

Background

TikiWiki is an open source content management system written in PHP.

Affected Packages

Package: www-apps/tikiwiki
Vulnerable: < 1.9.8.1
Unaffected: >= 1.9.8.1

Description

ShAnKaR reported that input passed to the "f" array parameter in tiki-graph_formula.php is not properly verified before being used to execute PHP functions.

Impact

An attacker could execute arbitrary code with the rights of the user running the web server by passing a specially crafted parameter string to the tiki-graph_formula.php file.

Workaround

There is no known workaround at this time.

Resolution

Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/tikiwiki-1.9.8.1"
