CVSS: 9.0EPSS: 0%CPEs: 14EXPL: 1CVE-2023-45134 – XWiki Platform XSS vulnerability from account in the create page form via template provider
https://notcve.org/view.php?id=CVE-2023-45134
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. `org.xwiki.platform:xwiki-platform-web` starting in version 3.1-milestone-1 and prior to 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.2 and 15.5-rc-1, and `org.xwiki.platform:xwiki-web-standard` starting in version 2.4-milestone-2 and prior to version 3.1-milestone-1 are vulnerable to cross-site scripting. An attacker can create a template provider on any document that is part of the wiki (could be the attacker's user profile) that contains malicious code. This code is executed when this template provider is selected during document creation which can be triggered by sending the user to a URL. For the attacker, the only requirement is to have an account as by default the own user profile is editable. • https://github.com/xwiki/xwiki-platform/commit/ba56fda175156dd35035f2b8c86cbd8ef1f90c2e https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-gr82-8fj2-ggc3 https://jira.xwiki.org/browse/XWIKI-20962 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 9.9EPSS: 0%CPEs: 2EXPL: 1CVE-2023-37913 – org.xwiki.platform:xwiki-platform-office-importer vulnerable to arbitrary server side file writing from account through office converter
https://notcve.org/view.php?id=CVE-2023-37913
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 3.5-milestone-1 and prior to versions 14.10.8 and 15.3-rc-1, triggering the office converter with a specially crafted file name allows writing the attachment's content to an attacker-controlled location on the server as long as the Java process has write access to that location. In particular in the combination with attachment moving, a feature introduced in XWiki 14.0, this is easy to reproduce but it also possible to reproduce in versions as old as XWiki 3.5 by uploading the attachment through the REST API which doesn't remove `/` or `\` from the filename. As the mime type of the attachment doesn't matter for the exploitation, this could e.g., be used to replace the `jar`-file of an extension which would allow executing arbitrary Java code and thus impact the confidentiality, integrity and availability of the XWiki installation. This vulnerability has been patched in XWiki 14.10.8 and 15.3RC1. • https://github.com/xwiki/xwiki-platform/commit/45d182a4141ff22f3ff289cf71e4669bdc714544 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vcvr-v426-3m3m https://jira.xwiki.org/browse/XWIKI-20715 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-23: Relative Path Traversal •
CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 3CVE-2023-37911 – org.xwiki.platform:xwiki-platform-oldcore may leak data through deleted and re-created documents
https://notcve.org/view.php?id=CVE-2023-37911
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 9.4-rc-1 and prior to versions 14.10.8 and 15.3-rc-1, when a document has been deleted and re-created, it is possible for users with view right on the re-created document but not on the deleted document to view the contents of the deleted document. Such a situation might arise when rights were added to the deleted document. This can be exploited through the diff feature and, partially, through the REST API by using versions such as `deleted:1` (where the number counts the deletions in the wiki and is thus guessable). Given sufficient rights, the attacker can also re-create the deleted document, thus extending the scope to any deleted document as long as the attacker has edit right in the location of the deleted document. • https://extensions.xwiki.org/xwiki/bin/view/Extension/Index%20Application#HPermanentlydeleteallpages https://github.com/xwiki/xwiki-platform/commit/f471f2a392aeeb9e51d59fdfe1d76fccf532523f https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-gh64-qxh5-4m33 https://jira.xwiki.org/browse/XWIKI-20684 https://jira.xwiki.org/browse/XWIKI-20685 https://jira.xwiki.org/browse/XWIKI-20817 • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 9.9EPSS: 0%CPEs: 1EXPL: 2CVE-2023-37909 – Privilege escalation (PR)/remote code execution from account through Menu.UIExtensionSheet
https://notcve.org/view.php?id=CVE-2023-37909
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 5.1-rc-1 and prior to versions 14.10.8 and 15.3-rc-1, any user who can edit their own user profile can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This has been patched in XWiki 14.10.8 and 15.3-rc-1 by adding proper escaping. As a workaround, the patch can be manually applied to the document `Menu.UIExtensionSheet`; only three lines need to be changed.

CVSS: 6.3EPSS: 0%CPEs: 2EXPL: 0CVE-2023-41046 – Velocity execution without script rights in Xwiki platform
https://notcve.org/view.php?id=CVE-2023-41046
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It is possible in XWiki to execute Velocity code without having script right by creating an XClass with a property of type "TextArea" and content type "VelocityCode" or "VelocityWiki". For the former, the syntax of the document needs to be set the `xwiki/1.0` (this syntax doesn't need to be installed). In both cases, when adding the property to an object, the Velocity code is executed regardless of the rights of the author of the property (edit right is still required, though). In both cases, the code is executed with the correct context author so no privileged APIs can be accessed. • https://github.com/xwiki/xwiki-platform/commit/edc52579eeaab1b4514785c134044671a1ecd839 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-m5m2-h6h9-p2c8 https://jira.xwiki.org/browse/XWIKI-20847 https://jira.xwiki.org/browse/XWIKI-20848 • CWE-862: Missing Authorization •
