CVSS: 9.9EPSS: 0%CPEs: 2EXPL: 1CVE-2023-37912 – XWiki Rendering's footnote macro vulnerable to privilege escalation via the footnote macro
https://notcve.org/view.php?id=CVE-2023-37912
XWiki Rendering is a generic Rendering system that converts textual input in a given syntax into another syntax. Prior to version 14.10.6 of `org.xwiki.platform:xwiki-core-rendering-macro-footnotes` and `org.xwiki.platform:xwiki-rendering-macro-footnotes` and prior to version 15.1-rc-1 of `org.xwiki.platform:xwiki-rendering-macro-footnotes`, the footnote macro executed its content in a potentially different context than the one in which it was defined. In particular in combination with the include macro, this allows privilege escalation from a simple user account in XWiki to programming rights and thus remote code execution, impacting the confidentiality, integrity and availability of the whole XWiki installation. This vulnerability has been patched in XWiki 14.10.6 and 15.1-rc-1. There is no workaround apart from upgrading to a fixed version of the footnote macro. • https://github.com/xwiki/xwiki-rendering/commit/5f558b8fac8b716d19999225f38cb8ed0814116e https://github.com/xwiki/xwiki-rendering/security/advisories/GHSA-35j5-m29r-xfq5 https://jira.xwiki.org/browse/XRENDERING-688 • CWE-270: Privilege Context Switching Error •
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: 8.1EPSS: 0%CPEs: 2EXPL: 1CVE-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 •
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: 9.6EPSS: 0%CPEs: 1EXPL: 3CVE-2023-37908 – org.xwiki.rendering:xwiki-rendering-xml Improper Neutralization of Invalid Characters in Identifiers in Web Pages vulnerability
https://notcve.org/view.php?id=CVE-2023-37908
XWiki Rendering is a generic Rendering system that converts textual input in a given syntax into another syntax. The cleaning of attributes during XHTML rendering, introduced in version 14.6-rc-1, allowed the injection of arbitrary HTML code and thus cross-site scripting via invalid attribute names. This can be exploited, e.g., via the link syntax in any content that supports XWiki syntax like comments in XWiki. When a user moves the mouse over a malicious link, the malicious JavaScript code is executed in the context of the user session. When this user is a privileged user who has programming rights, this allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. • https://github.com/xwiki/xwiki-rendering/commit/f4d5acac451dccaf276e69f0b49b72221eef5d2f https://github.com/xwiki/xwiki-rendering/security/advisories/GHSA-663w-2xp3-5739 https://github.com/xwiki/xwiki-rendering/security/advisories/GHSA-6gf5-c898-7rxp https://jira.xwiki.org/browse/XRENDERING-697 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-83: Improper Neutralization of Script in Attributes in a Web Page •
