All supported architectures
Tikiwiki contains a cross-site scripting (XSS) vulnerability as well as a
second vulnerability which may allow remote execution of arbitrary code.
Tikiwiki is a web-based groupware and content management system,
developed with PHP, ADOdb and Smarty.
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.
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.
There is no known workaround at this time.
All Tikiwiki users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --oneshot --verbose --ask ">=www-apps/tikiwiki-1.9.5"
