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: 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 •
