CVSS: 9.6EPSS: 0%CPEs: 1EXPL: 0CVE-2023-31126 – Improper Neutralization of Invalid Characters in Data Attribute Names in org.xwiki.commons:xwiki-commons-xml
https://notcve.org/view.php?id=CVE-2023-31126
`org.xwiki.commons:xwiki-commons-xml` is an XML library used by the open-source wiki platform XWiki. The HTML sanitizer, introduced in version 14.6-rc-1, allows the injection of arbitrary HTML code and thus cross-site scripting via invalid data attributes. This vulnerability does not affect restricted cleaning in HTMLCleaner as there attributes are cleaned and thus characters like `/` and `>` are removed in all attribute names. This problem has been patched in XWiki 14.10.4 and 15.0 RC1 by making sure that data attributes only contain allowed characters. There are no known workarounds apart from upgrading to a version including the fix. • https://github.com/xwiki/xwiki-commons/commit/0b8e9c45b7e7457043938f35265b2aa5adc76a68 https://github.com/xwiki/xwiki-commons/security/advisories/GHSA-pv7v-ph6g-3gxv https://jira.xwiki.org/browse/XCOMMONS-2606 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-86: Improper Neutralization of Invalid Characters in Identifiers in Web Pages •
CVSS: 9.0EPSS: 0%CPEs: 6EXPL: 1CVE-2023-29528 – Cross-site Scripting in org.xwiki.commons:xwiki-commons-xml
https://notcve.org/view.php?id=CVE-2023-29528
XWiki Commons are technical libraries common to several other top level XWiki projects. The "restricted" mode of the HTML cleaner in XWiki, introduced in version 4.2-milestone-1 and massively improved in version 14.6-rc-1, allowed the injection of arbitrary HTML code and thus cross-site scripting via invalid HTML comments. As a consequence, any code relying on this "restricted" mode for security is vulnerable to JavaScript injection ("cross-site scripting"/XSS). When a privileged user with programming rights visits such a comment in XWiki, the malicious JavaScript code is executed in the context of the user session. This allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. • https://github.com/xwiki/xwiki-commons/commit/8ff1a9d7e5d7b45b690134a537d53dc05cae04ab https://github.com/xwiki/xwiki-commons/security/advisories/GHSA-x37v-36wv-6v6h https://jira.xwiki.org/browse/XCOMMONS-2568 https://jira.xwiki.org/browse/XWIKI-20348 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

https://notcve.org/view.php?id=CVE-2023-29517
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The office document viewer macro was allowing anyone to see any file content from the hosting server, provided that the office server was connected and depending on the permissions of the user running the servlet engine (e.g. tomcat) running XWiki. The same vulnerability also allowed to perform internal requests to resources from the hosting server. The problem has been patched in XWiki 13.10.11, 14.10.1, 14.4.8, 15.0-rc-1. Users are advised to upgrade. • https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-m3c3-9qj7-7xmx https://jira.xwiki.org/browse/XWIKI-20324 https://jira.xwiki.org/browse/XWIKI-20447 https://jira.xwiki.org/browse/XWIKI-20449 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2023-29516
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with view rights on `XWiki.AttachmentSelector` can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping in the "Cancel and return to page" button. This page is installed by default. This vulnerability has been patched in XWiki 15.0-rc-1, 14.10.1, 14.4.8, and 13.10.11. • https://github.com/xwiki/xwiki-platform/commit/aca1d677c58563bbe6e35c9e1c29fd8b12ebb996 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-3989-4c6x-725f https://jira.xwiki.org/browse/XWIKI-20275 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 7.7EPSS: 0%CPEs: 3EXPL: 2CVE-2023-29515 – Cross-site scripting (XSS) in xwiki-platform
https://notcve.org/view.php?id=CVE-2023-29515
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user who can create a space can become admin of that space through App Within Minutes. The admin right implies the script right and thus allows JavaScript injection. The vulnerability can be exploited by creating an app in App Within Minutes. If the button should be disabled because the user doesn't have global edit right, the app can also be created by directly opening `/xwiki/bin/view/AppWithinMinutes/CreateApplication? • https://github.com/xwiki/xwiki-platform/commit/e73b890623efa604adc484ad82f37e31596fe1a6 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-44h9-xxvx-pg6x https://jira.xwiki.org/browse/XWIKI-20190 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
