DISPUTED CSV Injection (aka Excel Macro Injection or Formula Injection) in /lib/plugins/usermanager/admin.php in DokuWiki 2018-04-22a and earlier allows remote attackers to exfiltrate sensitive data and to execute arbitrary code via a value that is mishandled in a CSV export. NOTE: the vendor has stated "this is not a security problem in DokuWiki."

The call parameter of /lib/exe/ajax.php in DokuWiki through 2017-02-19e does not properly encode user input, which leads to a reflected file download vulnerability, and allows remote attackers to run arbitrary programs.

The sendRequest method in HTTPClient Class in file /inc/HTTPClient.php in DokuWiki 2016-06-26a and older, when media file fetching is enabled, has no way to restrict access to private networks. This allows users to scan ports of internal networks via SSRF, such as 10.0.0.1/8, 172.16.0.0/12, and 192.168.0.0/16.

DISPUTED Cross-site request forgery (CSRF) vulnerability in doku.php in DokuWiki 2012-01-25 Angua allows remote attackers to hijack the authentication of administrators for requests that add arbitrary users. NOTE: this issue has been disputed by the vendor, who states that it is resultant from CVE-2012-2129: "the exploit code simply uses the XSS hole to extract a valid CSRF token."

DokuWiki before 2014-05-05d and before 2014-09-29c does not properly check permissions for the ACL plugins, which allows remote authenticated users to gain privileges and add or delete ACL rules via a request to the XMLRPC API.

DokuWiki 2016-06-26a and older uses $SERVER[HTTPHOST] instead of the baseurl setting as part of the password-reset URL. This can lead to phishing attacks. (A remote unauthenticated attacker can change the URL's hostname via the HTTP Host header.) The vulnerability can be triggered only if the Host header is not part of the web server routing process (e.g., if several domains are served by the same web server).

DokuWiki through 2017-02-19b has XSS in the at parameter (aka the DATEAT variable) to doku.php.

DokuWiki through 2017-02-19c has stored XSS when rendering a malicious RSS or Atom feed, in /inc/parser/xhtml.php. An attacker can create or edit a wiki that uses RSS or Atom data from an attacker-controlled server to trigger JavaScript execution. The JavaScript can be in an author field, as demonstrated by the dc:creator element.

DokuWiki through 2017-02-19c has stored XSS when rendering a malicious language name in a code element, in /inc/parser/xhtml.php. An attacker can create or edit a wiki with this element to trigger JavaScript execution.

HTMLCreator releasestable2020-07-29 was discovered to contain a cross-site scripting (XSS) vulnerability via the function generateFilename.

Cross-site Scripting (XSS) - Reflected in GitHub repository splitbrain/dokuwiki prior to 2022-07-31a.

A Cross-site Scripting (XSS) vulnerability exists in version v2024-01-05 of the indexmenu plugin when is used and enabled in Dokuwiki (Open Source Wiki Engine). A malicious attacker can input XSS payloads for example when creating or editing existing page, to trigger the XSS on Dokuwiki, which is then stored in .txt file (due to nature of how Dokuwiki is designed), which presents stored XSS.

DokuWiki 2009-12-25c allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by lib/tpl/index.php and certain other files.

DokuWiki 2014-05-05a and earlier, when using Active Directory for LDAP authentication, allows remote attackers to bypass authentication via a user name and password starting with a null (\0) character, which triggers an anonymous bind.

The ajaxmediadiff function in DokuWiki before 2014-05-05a allows remote attackers to access arbitrary images via a crafted namespace in the ns parameter.

inc/template.php in DokuWiki before 2014-05-05a only checks for access to the root namespace, which allows remote attackers to access arbitrary images via a media file details ajax call.

DokuWiki before 2014-05-05b, when using Active Directory for LDAP authentication, allows remote attackers to bypass authentication via a password starting with a null (\0) character and a valid user name, which triggers an unauthenticated bind.

Cross-site scripting (XSS) vulnerability in the tplmediaFileList function in inc/template.php in DokuWiki before 2012-01-25b allows remote attackers to inject arbitrary web script or HTML via the ns parameter in a medialist action to lib/exe/ajax.php.

Cross-site scripting (XSS) vulnerability in doku.php in DokuWiki 2012-01-25 Angua allows remote attackers to inject arbitrary web script or HTML via the target parameter in an edit action.

The default file type whitelist configuration in conf/mime.conf in the Media Manager in DokuWiki before 2014-09-29b allows remote attackers to execute arbitrary web script or HTML by uploading an SWF file, then accessing it via the media parameter to lib/exe/fetch.php.

Cross-site scripting (XSS) vulnerability in the RSS embedding feature in DokuWiki before 2011-05-25a Rincewind allows remote attackers to inject arbitrary web script or HTML via a link.

A cross-site scripting (XSS) and cross-site request forgery (CSRF) flaws were found in the way DokuWiki, a standards compliant, simple to use Wiki, performed sanitization of the 'target' parameter when preprocessing edit form data. A remote attacker could provide a specially-crafted URL, which once visited by a valid DokuWiki user would lead to arbitrary HTML or web script execution in the context of logged in DokuWiki user.

Discovered by : Khashayar Fereidani

Proof of Concept URL: http://sitename/doku.php?do=edit&id=S9F8W2A&target=<script>alert(123)</script>

It was found that DokuWiki's RSS embedding mechanism did not properly escape user-provided links. An attacker could use this flaw to conduct cross-site scripting (XSS) attacks, potentially leading to arbitrary JavaScript code execution.
