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.

The Calendar component in Tiki 17.1 allows HTML injection.

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.

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.

An XSS vulnerability (via an SVG image) in Tiki before 18 allows an authenticated user to gain administrator privileges if an administrator opens a wiki page with a malicious SVG image, related to lib/filegals/filegallib.php.

Cross-site scripting (XSS) vulnerability in TikiWiki (Tiki) CMS/Groupware 2.2 allows remote attackers to inject arbitrary web script or HTML via the PHPSELF portion of a URI to (1) tiki-galleries.php, (2) tiki-listfilegallery.php, (3) tiki-listpages.php, and (4) tiki-orphanpages.php.

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.

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 /vendorextra/elfinder/.

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.

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.

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.

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.

The userlogout 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-featuredlink.php in Tikiwiki 1.9.5 allows remote attackers to inject arbitrary web script or HTML via a url parameter that evades filtering, as demonstrated by a parameter value containing malformed, nested SCRIPT elements.

Tikiwiki 1.9.5 allows remote attackers to obtain sensitive information (MySQL username and password) via an empty sortmode parameter in (1) tiki-listpages.php, (2) tiki-lastchanges.php, (3) messu-archive.php, (4) messu-mailbox.php, (5) messu-sent.php, (6) tiki-directoryaddsite.php, (7) tiki-directoryranking.php, (8) tiki-directorysearch.php, (9) tiki-forums.php, (10) tiki-viewforum.php, (11) tiki-friends.php, (12) tiki-listblogs.php, (13) tiki-listfaqs.php, (14) tiki-listtrackers.php, (15) tiki-listusers.php, (16) tiki-mytiki.php, (17) tiki-notepadlist.php, (18) tiki-orphanpages.php, (19) tiki-shoutbox.php, (20) tiki-usermenu.php, and (21) tiki-webmailcontacts.php, which reveal the information in certain database error messages.

tiki-wikirss.php in Tikiwiki 1.9.5, 1.9.2, and possibly other versions allows remote attackers to obtain sensitive information (MySQL username and password) via an invalid (large or negative) ver parameter, which leaks the information in an error message.

Cross-site scripting (XSS) vulnerability in tiki-setupbase.php in TikiWiki before 1.9.7 allows remote attackers to inject arbitrary JavaScript via unspecified parameters.

Cross-site scripting (XSS) vulnerability in tiki-editstructures.php in TikiWiki 1.9.6 allows remote attackers to inject arbitrary web script or HTML via the pageAlias parameter. NOTE: The provenance of this information is unknown; the details are obtained solely from third party information.

tiki-register.php in TikiWiki before 1.9.7 allows remote attackers to trigger "notification-spam" via certain vectors such as a comma-separated list of addresses in the email field, related to lack of "a minimal check on email."

A Reflected Cross-Site Scripting (XSS) vulnerability exists in the POST request data zipPath of tiki-adminsystem.php in Tiki version 21.2. This vulnerability allows attackers to execute arbitrary JavaScript code via a crafted payload, leading to potential access to sensitive information or unauthorized actions.

A Cross-Site Scripting (XSS) vulnerability exists in the page parameter of tiki-editpage.php in Tiki version 26.3 and earlier. This vulnerability allows attackers to execute arbitrary JavaScript code via a crafted payload, leading to potential access to sensitive information or unauthorized actions.

wikipluginincludetpl in lib/wiki-plugins/wikipluginincludetpl.php in Tiki before 28.3 mishandles input to an eval. The fixed versions are 21.12, 24.8, 27.2, and 28.3.

Tiki through 27.0 allows users who have certain permissions to insert a "Create/Edit External Wiki" stored XSS payload in the Index.

Tiki through 27.0 allows users who have certain permissions to insert a "Modules" (aka tiki-adminmodules.php) stored XSS payload in the Name.

Tiki through 27.0 allows users who have certain permissions to insert a "Create/Edit External Wiki" stored XSS payload in the Name.

Tiki through 27.0 allows users who have certain permissions to insert a "Create a Wiki Pages" stored XSS payload in the description.

Tiki through 25.0 allows CSRF attacks that are related to tiki-importer.php and tiki-importsheet.php.

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