Xwiki

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Versions 10.4-rc-1, through 16.10.15, 17.0.0-rc-1, through 17.4.7 and 17.5.0-rc-1 through 17.10.0 contain a reflected cross-site scripting vulnerability (XSS) in the comparison view between revisions of a page allows executing JavaScript code in the user's browser. If the current user is an admin, this can not only affect the current user but also the confidentiality, integrity and availability of the whole XWiki instance. If developers are unable to update immediately, they can apply the patch manually to templates/changesdoc.vm in the deployed WAR.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Versions 1.8-rc-1, 17.0.0-rc-1 and 17.5.0-rc-1 and prior include a resource exhaustion vulnerability in REST API endpoints such as /xwiki/rest/wikis/xwiki/spaces/AnnotationCode/pages/AnnotationConfig/objects/AnnotationCode.AnnotationConfig/0/properties, which list all available pages as part of the metadata for database list properties without applying query limits. On large wikis, this can exhaust available server resources. This issue has been patched in versions 16.10.16, 17.4.8 and 17.10.1.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Prior to 17.4.8 and 17.10.1, an improperly protected scripting API allows any user with script right to bypass the sandboxing of the Velocity scripting API and execute, e.g., arbitrary Python scripts, allowing full access to the XWiki instance and thereby compromising the confidentiality, integrity and availability of the whole instance. Note that script right already constitutes a high level of access that we don't recommend giving to untrusted users. This vulnerability is fixed in 17.4.8 and 17.10.1.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Prior to 17.9.0, 17.4.6, and 16.10.13, it's possible using comments to inject CSS that would transform the full wiki in a link area leading to a malicious page. This vulnerability is fixed in 17.9.0, 17.4.6, and 16.10.13.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Versions 7.0-milestone-2 through 16.10.11, 17.0.0-rc-1 through 17.4.4, and 17.5.0-rc-1 through 17.7.0 contain a reflected Cross-site Scripting (XSS) vulnerability, which allows an attacker to craft a malicious URL and execute arbitrary actions with the same privileges as the victim. If the victim has administrative or programming rights, those rights can be exploited to gain full access to the XWiki installation. This issue has been patched in versions 17.8.0-rc-1, 17.4.5 and 16.10.12. To workaround, the patch can be applied manually, only a single line in templates/logging_macros.vm needs to be changed, no restart is required.Show less

XWiki is an open-source wiki software platform. Versions 16.10.10 and below, 17.0.0-rc-1 through 17.4.3 and 17.5.0-rc-1 through 17.6.0 contain a REST API which doesn't enforce any limits for the number of items that can be requested in a single request at the moment. Depending on the number of pages in the wiki and the memory configuration, this can lead to slowness and unavailability of the wiki. As an example, the /rest/wikis/xwiki/spaces resource returns all spaces on the wiki by default, which are basically all pages. This issue is fixed in versions 17.4.4 and 16.10.11.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Versions 6.2-milestone-1 through 16.10.9 and 17.0.0-rc-1 through 17.4.1 of both XWiki Platform Flamingo Skin Resources and XWiki Platform Web Templates are vulnerable to a reflected XSS attack through a deletion confirmation message. The attacker-supplied script is executed when the victim clicks the "No" button. This issue is fixed in versions 16.10.10 and 17.4.2 of both XWiki Platform Flamingo Skin Resources and XWiki Platform Web Templates.Show less

XWiki is an open-source wiki software platform. From 16.7.0 to 16.10.11, 17.4.4, or 17.7.0, in an instance which is using the XWiki Jetty package (XJetty), a context is exposed to statically access any file located in the webapp/ folder. It allows accessing files which might contains credentials. Fixed in 16.10.11, 17.4.4, and 17.7.0.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions 4.2-milestone-2 through 16.10.6, configuration files are accessible through jsx and sx endpoints. It's possible to access and read configuration files by using URLs such as `http://localhost:8080/bin/ssx/Main/WebHome?resource=../../WEB-INF/xwiki.cfg&minify=false`. This is fixed in version 16.10.7.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions 6.1-milestone-2 through 16.10.6, configuration files are accessible through the webjars API. This is fixed in version 16.10.7.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions from 14.4.2 to before 16.4.8, 16.5.0-rc-1 to before 16.10.7, and 17.0.0-rc-1 to before 17.4.0-rc-1, the PDF export jobs store sensitive cookies unencrypted in job statuses. XWiki shouldn't store passwords in plain text, and it shouldn't be possible to gain access to plain text passwords by gaining access to, e.g., a backup of the data directory. This vulnerability has been patched in XWiki 16.4.8, 16.10.7, and 17.4.0-rc-1.Show less

XWiki through version 17.3.0 is vulnerable to Server-Side Template Injection (SSTI) in the Administration interface, specifically within the HTTP Meta Info field of the Global Preferences Presentation section. An authenticated administrator can inject crafted Apache Velocity template code, which is rendered on the server side without proper validation or sandboxing. This enables the execution of arbitrary template logic, which may expose internal server information or, in specific configurations, lead to further exploitation such as remote code execution or sensitive data leakage. The vulnerability resides in improper handling of dynamic template rendering within user-supplied configuration fields.Show less

XWiki through version 17.3.0 is affected by multiple stored Cross-Site Scripting (XSS) vulnerabilities in the Administration interface, specifically under the Presentation section of the Global Preferences panel. An authenticated administrator can inject arbitrary JavaScript payloads into the HTTP Meta Info, Footer Copyright, and Footer Version fields. These inputs are stored and subsequently rendered without proper output encoding or sanitization on public-facing pages. As a result, the injected scripts are persistently executed in the browser context of any visitor to the affected instances including both authenticated and unauthenticated users. No user interaction is required beyond visiting a page that includes the malicious content. Successful exploitation can lead to session hijacking, credential theft, unauthorized actions via session riding, or further compromise of the application through client-side attacks. The vulnerability introduces significant risk in any deployment, especially in shared or internet-facing environments where administrator credentials may be compromised.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki Platform Legacy Old Core and XWiki Platform Old Core versions 1.1 through 16.4.6, 16.5.0-rc-1 through 16.10.4 and 17.0.0-rc-1 through 17.1.0, the XML export of a page in XWiki that can be triggered by any user with view rights on a page by appending ?xpage=xml to the URL includes password and email properties stored on a document that aren't named password or email. This is fixed in versions 16.4.7, 16.10.5 and 17.2.0-rc-1. To work around this issue, the file templates/xml.vm in the deployed WAR can be deleted if the XML isn't needed. There isn't any feature in XWiki itself that depends on the XML export.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki Platform Legacy Old Core and XWiki Platform Old Core versions 9.8-rc-1 through 16.4.6, 16.5.0-rc-1 through 16.10.4, and 17.0.0-rc-1 through 17.1.0, any user with editing rights can create an XClass with a database list property that references a password property. When adding an object of that XClass, the content of that password property is displayed. In practice, with a standard rights setup, this means that any user with an account on the wiki can access password hashes of all users, and possibly other password properties (with hashed or plain storage) that are on pages that the user can view. This issue is fixed in versions 16.4.7, 16.10.5 and 17.2.0-rc-1.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions 4.2-milestone-3 through 16.4.7, 16.5.0-rc-1 through 16.10.5 and 17.0.0-rc-1 through 17.2.2, two templates contain reflected XSS vulnerabilities, allowing an attacker to execute malicious JavaScript code in the context of the victim's session by getting the victim to visit an attacker-controlled URL. This permits the attacker to perform arbitrary actions using the permissions of the victim. This issue is fixed in versions 16.4.8, 16.10.6 and 17.3.0-rc-1. To workaround the issue, manually patch the WAR with the same changes as the original patch.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions between 17.0.0-rc1 to 17.2.2 and versions 16.10.5 and below, it's possible to execute any SQL query in Oracle by using the function like DBMS_XMLGEN or DBMS_XMLQUERY. The XWiki#searchDocuments APIs pass queries directly to Hibernate without sanitization. Even when these APIs enforce a specific SELECT clause, attackers can still inject malicious code through HQL's native function support in other parts of the query (such as the WHERE clause). This is fixed in versions 16.10.6 and 17.3.0-rc-1.Show less

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions 9.4-rc-1 through 16.10.5 and 17.0.0-rc-1 through 17.2.2, it's possible for anyone to inject SQL using the parameter sort of the getdeleteddocuments.vm. It's injected as is as an ORDER BY value. This is fixed in versions 16.10.6 and 17.3.0-rc-1.Show less

XWiki Rendering is a generic rendering system that converts textual input in a given syntax (wiki syntax, HTML, etc) into another syntax (XHTML, etc). Starting in version 4.2-milestone-1 and prior to versions 13.10.11, 14.4.7, and 14.10, the default macro content parser doesn't preserve the restricted attribute of the transformation context when executing nested macros. This allows executing macros that are normally forbidden in restricted mode, in particular script macros. The cache and chart macros that are bundled in XWiki use the vulnerable feature. This has been patched in XWiki 13.10.11, 14.4.7 and 14.10. To avoid the exploitation of this bug, comments can be disabled for untrusted users until an upgrade to a patched version has been performed. Note that users with edit rights will still be able to add comments via the object editor even if comments have been disabled.Show less

XWiki Rendering is a generic rendering system that converts textual input in a given syntax (wiki syntax, HTML, etc) into another syntax (XHTML, etc). Starting in version 5.4.5 and prior to version 14.10, the XHTML syntax depended on the `xdom+xml/current` syntax which allows the creation of raw blocks that permit the insertion of arbitrary HTML content including JavaScript. This allows XSS attacks for users who can edit a document like their user profile (enabled by default). This has been fixed in version 14.10 by removing the dependency on the `xdom+xml/current` syntax from the XHTML syntax. Note that the `xdom+xml` syntax is still vulnerable to this attack. As it's main purpose is testing and its use is quite difficult, this syntax shouldn't be installed or used on a regular wiki. There are no known workarounds apart from upgrading.Show less
