CVSS: 9.0EPSS: 0%CPEs: 4EXPL: 2CVE-2023-45135 – XWiki users can be tricked to execute scripts as the create page action doesn't display the page's title
https://notcve.org/view.php?id=CVE-2023-45135
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In `org.xwiki.platform:xwiki-platform-web` versions 7.2-milestone-2 until 14.10.12 and `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.12 and 15.5-rc-1, it is possible to pass a title to the page creation action that isn't displayed at first but then executed in the second step. This can be used by an attacker to trick a victim to execute code, allowing script execution if the victim has script right or remote code execution including full access to the XWiki instance if the victim has programming right. For the attack to work, the attacker needs to convince the victim to visit a link like `<xwiki-host>/xwiki/bin/create/NonExistingSpace/WebHome?title=$services.logging.getLogger(%22foo%22).error(%22Script%20executed!%22)` where `<xwiki-host>` is the URL of the Wiki installation and to then click on the "Create" button on that page. • https://github.com/xwiki/xwiki-platform/commit/199e27ce7016757e66fa7cea99e718044a1b639b https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-ghf6-2f42-mjh9 https://jira.xwiki.org/browse/XWIKI-20869 • CWE-116: Improper Encoding or Escaping of Output •
CVSS: 9.0EPSS: 0%CPEs: 14EXPL: 1CVE-2023-45134 – XWiki Platform XSS vulnerability from account in the create page form via template provider
https://notcve.org/view.php?id=CVE-2023-45134
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. `org.xwiki.platform:xwiki-platform-web` starting in version 3.1-milestone-1 and prior to 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.2 and 15.5-rc-1, and `org.xwiki.platform:xwiki-web-standard` starting in version 2.4-milestone-2 and prior to version 3.1-milestone-1 are vulnerable to cross-site scripting. An attacker can create a template provider on any document that is part of the wiki (could be the attacker's user profile) that contains malicious code. This code is executed when this template provider is selected during document creation which can be triggered by sending the user to a URL. For the attacker, the only requirement is to have an account as by default the own user profile is editable. • https://github.com/xwiki/xwiki-platform/commit/ba56fda175156dd35035f2b8c86cbd8ef1f90c2e https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-gr82-8fj2-ggc3 https://jira.xwiki.org/browse/XWIKI-20962 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 9.9EPSS: 0%CPEs: 2EXPL: 1CVE-2023-37913 – org.xwiki.platform:xwiki-platform-office-importer vulnerable to arbitrary server side file writing from account through office converter
https://notcve.org/view.php?id=CVE-2023-37913
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 3.5-milestone-1 and prior to versions 14.10.8 and 15.3-rc-1, triggering the office converter with a specially crafted file name allows writing the attachment's content to an attacker-controlled location on the server as long as the Java process has write access to that location. In particular in the combination with attachment moving, a feature introduced in XWiki 14.0, this is easy to reproduce but it also possible to reproduce in versions as old as XWiki 3.5 by uploading the attachment through the REST API which doesn't remove `/` or `\` from the filename. As the mime type of the attachment doesn't matter for the exploitation, this could e.g., be used to replace the `jar`-file of an extension which would allow executing arbitrary Java code and thus impact the confidentiality, integrity and availability of the XWiki installation. This vulnerability has been patched in XWiki 14.10.8 and 15.3RC1. • https://github.com/xwiki/xwiki-platform/commit/45d182a4141ff22f3ff289cf71e4669bdc714544 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vcvr-v426-3m3m https://jira.xwiki.org/browse/XWIKI-20715 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-23: Relative Path Traversal •
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 •
