What is CVE-2020-29254?
CVE-2020-29254 is a high-severity vulnerability in Tiki Tikiwiki Cms\/Groupware, published on 11 Dec 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
