CVSS: 9.0EPSS: 0%CPEs: 1EXPL: 4CVE-2023-29201 – org.xwiki.commons:xwiki-commons-xml Cross-site Scripting vulnerability
https://notcve.org/view.php?id=CVE-2023-29201
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, only escaped `<script>` and `<style>`-tags but neither attributes that can be used to inject scripts nor other dangerous HTML tags like `<iframe>`. 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/4a185e0594d90cd4916d60aa60bb4333dc5623b2 https://github.com/xwiki/xwiki-commons/commit/b11eae9d82cb53f32962056b5faa73f3720c6182 https://github.com/xwiki/xwiki-commons/security/advisories/GHSA-m3jr-cvhj-f35j https://jira.xwiki.org/browse/XCOMMONS-1680 https://jira.xwiki.org/browse/XCOMMONS-2426 https://jira.xwiki.org/browse/XWIKI-9118 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 7.7EPSS: 0%CPEs: 5EXPL: 2CVE-2023-27480 – Data leak through a XAR import XXE attack in xwiki-platform-xar-model
https://notcve.org/view.php?id=CVE-2023-27480
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions any user with edit rights on a document can trigger an XAR import on a forged XAR file, leading to the ability to display the content of any file on the XWiki server host. This vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10-rc-1. Users are advised to upgrade. Users unable to upgrade may apply the patch `e3527b98fd` manually. • https://github.com/xwiki/xwiki-platform/commit/e3527b98fdd8dc8179c24dc55e662b2c55199434 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-gx4f-976g-7g6v https://jira.xwiki.org/browse/XWIKI-20320 • CWE-611: Improper Restriction of XML External Entity Reference •
CVSS: 9.9EPSS: 0%CPEs: 6EXPL: 2CVE-2023-27479 – Improper Neutralization of Directives in Dynamically Evaluated Code in org.xwiki.platform:xwiki-platform-panels-ui
https://notcve.org/view.php?id=CVE-2023-27479
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions any user with view rights can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of UIX parameters. A proof of concept exploit is to log in, add an `XWiki.UIExtensionClass` xobject to the user profile page, with an Extension Parameters content containing `label={{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}`. • https://github.com/xwiki/xwiki-platform/commit/6de5442f3c91c3634a66c7b458d5b142e1c2a2dc https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-qxjg-jhgw-qhrv https://jira.xwiki.org/browse/XWIKI-20294 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

XWiki Platform is a generic wiki platform. Starting in version 3.0-milestone-1, it's possible to execute a script with the right of another user, provided the target user does not have programming right. The problem has been patched in XWiki 14.8-rc-1, 14.4.5, and 13.10.10. There are no known workarounds for this issue. • https://github.com/xwiki/xwiki-platform/commit/4b75f212c2dd2dfc5fb5726c7830c6dbc9a425c6 https://github.com/xwiki/xwiki-platform/commit/bd34ad6710ed72304304a3d5fec38b7cc050ef3b https://github.com/xwiki/xwiki-platform/commit/dd3f4735b41971b3afc3f3aedf6664b4e8be4894 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-859x-p6jp-rc2w https://jira.xwiki.org/browse/XWIKI-19856 • CWE-863: Incorrect Authorization •

https://notcve.org/view.php?id=CVE-2023-26470
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It's possible to make the farm unusable by adding an object to a page with a huge number (e.g. 67108863). Most of the time this will fill the memory allocated to XWiki and make it unusable every time this document is manipulated. This issue has been patched in XWiki 14.0-rc-1. • https://github.com/xwiki/xwiki-platform/commit/04e5a89d2879b160cdfaea846024d3d9c1a525e6 https://github.com/xwiki/xwiki-platform/commit/db3d1c62fc5fb59fefcda3b86065d2d362f55164 https://github.com/xwiki/xwiki-platform/commit/fdfce062642b0ac062da5cda033d25482f4600fa https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-92wp-r7hm-42g7 https://jira.xwiki.org/browse/XWIKI-19223 • CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •
