TikiWiki CMS/Groupware before 6.7 LTS and before 8.4 allows remote attackers to execute arbitrary PHP code via a crafted serialized object in the (1) cookieName to lib/banners/bannerlib.php; (2) printpages or (3) printstructures parameter to (a) tiki-print_multi_pages.php or (b) tiki-print_pages.php; or (4) sendpages, (5) sendstructures, or (6) sendarticles parameter to tiki-send_objects.php, which is not properly handled when processed by the unserialize function.

TikiWiki CMS/Groupware 8.3 and earlier allows remote attackers to obtain the installation path via a direct request to (1) admin/include_calendar.php, (2) tiki-rss_error.php, or (3) tiki-watershed_service.php.

tiki-featured_link.php in TikiWiki CMS/Groupware 8.3 allows remote attackers to load arbitrary web site pages into frames and conduct phishing attacks via the url parameter, aka "frame injection."

Cross-site scripting (XSS) vulnerability in Tiki Wiki CMS Groupware 6 LTS before 6.13LTS, 9 LTS before 9.7LTS, 10.x before 10.4, and 11.x before 11.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

SQL injection vulnerability in Tiki Wiki CMS Groupware 6 LTS before 6.13LTS, 9 LTS before 9.7LTS, 10.x before 10.4, and 11.x before 11.1 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

Tiki before 24.1, when feature_create_webhelp is enabled, allows lib/structures/structlib.php PHP Object Injection because of an eval.

Tiki before 24.1, when the Spreadsheets feature is enabled, allows lib/sheet/grid.php PHP Object Injection because of an unserialize call.

Tiki before 24.2 allows lib/importer/tikiimporter_blog_wordpress.php PHP Object Injection by an admin because of an unserialize call.

Cross Site Scripting (XSS) flaws found in Tiki-Wiki CMS software

There is an Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) vulnerability in php webpages of Tiki-Wiki Groupware. Tiki-Wiki CMS all versions through 20.0 allows malicious users to cause the injection of malicious code fragments (scripts) into a legitimate web page.

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.

Tiki before 21.2 allows XSS because [\s\/"\'] is not properly considered in lib/core/TikiFilter/PreventXss.php.

tiki-login.php in Tiki before 21.2 sets the admin password to a blank value after 50 invalid login attempts.

tiki/tiki-upload_file.php in Tiki 18.4 allows remote attackers to upload JavaScript code that is executed upon visiting a tiki/tiki-download_file.php?display&fileId= URI.

Tiki 17.1 does not validate user input for special characters; consequently, a CSV Injection attack can open a CMD.EXE or Calculator window on the victim machine to perform malicious activity, as demonstrated by an "=cmd|' /C calc'!A0" payload during User Creation.

The Calendar component in Tiki 17.1 allows HTML injection.

Tiki 17.1 allows upload of a .PNG file that actually has SVG content, leading to XSS.

Cross Site Scripting (XSS) exists in Tiki before 12.13, 15.6, 17.2, and 18.1.
