Tikiwiki contains a command injection vulnerability which may allow remote execution of arbitrary code.
|Package||www-apps/tikiwiki on all architectures|
|Affected versions||< 22.214.171.124|
|Unaffected versions||>= 126.96.36.199|
TikiWiki is an open source content management system written in PHP.
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.
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.
There is no known workaround at this time.
All TikiWiki users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/tikiwiki-188.8.131.52"
