An authenticated command injection vulnerability exists in Tiki Wiki CMS versions ≤14.1, ≤12.4 LTS, ≤9.10 LTS, and ≤6.14 via the viewmode GET parameter in tiki-calendar.php. When the calendar module is enabled and an authenticated user has permission to access it, an attacker can inject and execute arbitrary PHP code. Successful exploitation leads to remote code execution in the context of the web server user.

TikiWiki 21.2 allows templates to be edited without CSRF protection. This could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface of the affected system. An attacker could exploit this vulnerability by persuading a user of the interface to follow a maliciously crafted link. A successful exploit could allow the attacker to perform arbitrary actions on an affected system with the privileges of the user. These action include allowing attackers to submit their own code through an authenticated user resulting in local file Inclusion. If an authenticated user who is able to edit TikiWiki templates visits an malicious website, template code can be edited.
