https://notcve.org/view.php?id=CVE-2023-29203
XWiki Commons are technical libraries common to several other top level XWiki projects. It's possible to list some users who are normally not viewable from subwiki by requesting users on a subwiki which allows only global users with `uorgsuggest.vm`. This issue only concerns hidden users from main wiki. Note that the disclosed information are the username and the first and last name of users, no other information is leaked. The problem has been patched on XWiki 13.10.8, 14.4.3 and 14.7RC1. • https://github.com/xwiki/xwiki-platform/pull/1883 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vvp7-r422-rx83 https://jira.xwiki.org/browse/XWIKI-20007 • CWE-359: Exposure of Private Personal Information to an Unauthorized Actor CWE-668: Exposure of Resource to Wrong Sphere •

https://notcve.org/view.php?id=CVE-2023-29202
XWiki Commons are technical libraries common to several other top level XWiki projects. The RSS macro that is bundled in XWiki included the content of the feed items without any cleaning in the HTML output when the parameter `content` was set to `true`. This allowed arbitrary HTML and in particular also JavaScript injection and thus cross-site scripting (XSS) by specifying an RSS feed with malicious content. With the interaction of a user with programming rights, this could be used to execute arbitrary actions in the wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting content and sabotaging the wiki. The issue has been patched in XWiki 14.6 RC1, the content of the feed is now properly cleaned before being displayed. • https://github.com/xwiki/xwiki-platform/commit/5c7ebe47c2897e92d8f04fe2e15027e84dc3ec03 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-c885-89fw-55qr https://jira.xwiki.org/browse/XWIKI-19671 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
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 •

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') •
