CVE-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 •

CVE-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 •

CVE-2023-37910 – org.xwiki.platform:xwiki-platform-attachment-api vulnerable to Missing Authorization on Attachment Move

https://notcve.org/view.php?id=CVE-2023-37910

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting with the introduction of attachment move support in version 14.0-rc-1 and prior to versions 14.4.8, 14.10.4, and 15.0-rc-1, an attacker with edit access on any document (can be the user profile which is editable by default) can move any attachment of any other document to this attacker-controlled document. This allows the attacker to access and possibly publish any attachment of which the name is known, regardless if the attacker has view or edit rights on the source document of this attachment. Further, the attachment is deleted from the source document. This vulnerability has been patched in XWiki 14.4.8, 14.10.4, and 15.0 RC1. • https://github.com/xwiki/xwiki-platform/commit/d7720219d60d7201c696c3196c9d4a86d0881325 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-rwwx-6572-mp29 https://jira.xwiki.org/browse/XWIKI-20334 • CWE-862: Missing Authorization •

CVE-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.

CVE-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 •
