Tiki Wiki CMS Authenticated Command Injection in Calendar Module

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.

Tiki Wiki <= 15.1 ELFinder Unauthenticated File Upload RCE

An unauthenticated arbitrary file upload vulnerability exists in Tiki Wiki CMS Groupware version 15.1 and earlier via the ELFinder component's default connector (connector.minimal.php), which allows remote attackers to upload and execute malicious PHP scripts in the context of the web server. The vulnerable component does not enforce file type validation, allowing attackers to craft a POST request to upload executable PHP payloads through the ELFinder interface exposed at /vendor_extra/elfinder/.

TikiFilter.php in Tiki Wiki CMS Groupware 12.x through 16.x does not properly validate the imgsize or lang parameter to prevent XSS.

Cross-Site Request Forgery (CSRF) vulnerability via IMG element in Tiki before 16.3, 17.x before 17.1, 12 LTS before 12.12 LTS, and 15 LTS before 15.5 LTS allows an authenticated user to edit global permissions if an administrator opens a wiki page with an IMG element, related to tiki-objectpermissions.php. For example, an attacker could assign administrator privileges to every unauthenticated user of the site.

Cross-Site Request Forgery (CSRF) vulnerability via IMG element in Tiki before 16.3, 17.x before 17.1, 12 LTS before 12.12 LTS, and 15 LTS before 15.5 LTS allows an authenticated user to gain administrator privileges if an administrator opens a wiki page with an IMG element, related to tiki-assignuser.php.

lib/core/TikiFilter/PreventXss.php in Tiki Wiki CMS Groupware 16.2 allows remote attackers to bypass the XSS filter via padded zero characters, as demonstrated by an attack on tiki-batch_send_newsletter.php.

A vulnerability in Tiki Wiki CMS 15.2 could allow a remote attacker to read arbitrary files on a targeted system via a crafted pathname in a banner URL field.

Some forms with the parameter geo_zoomlevel_to_found_location in Tiki Wiki CMS 12.x before 12.10 LTS, 15.x before 15.3 LTS, and 16.x before 16.1 don't have the input sanitized, related to tiki-setup.php and article_image.php. The impact is XSS.

SQL injection vulnerability in the _find function in searchlib.php in TikiWiki CMS/Groupware 3.x before 3.5 allows remote attackers to execute arbitrary SQL commands via the $searchDate variable.

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.

Multiple SQL injection vulnerabilities in TikiWiki CMS/Groupware 4.x before 4.2 allow remote attackers to execute arbitrary SQL commands via unspecified vectors, probably related to (1) tiki-searchindex.php and (2) tiki-searchresults.php.

The Standard Remember method in TikiWiki CMS/Groupware 3.x before 3.5 allows remote attackers to bypass access restrictions related to "persistent login," probably due to the generation of predictable cookies based on the IP address and User agent in userslib.php.

The user_logout function in TikiWiki CMS/Groupware 4.x before 4.2 does not properly delete user login cookies, which allows remote attackers to gain access via cookie reuse.

Cross-site scripting (XSS) vulnerability in tiki-cookie-jar.php in TikiWiki CMS/Groupware before 8.2 and LTS before 6.5 allows remote attackers to inject arbitrary web script or HTML via arbitrary parameters.

TikiWiki v21.4 was discovered to contain a cross-site scripting (XSS) vulnerability in the component tiki-calendar.php. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload under the Add Event module.

TikiWiki v21.4 was discovered to contain a cross-site scripting (XSS) vulnerability in the component tiki-browse_categories.php. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload under the Create category module.
