CVSS: 9.6EPSS: 0%CPEs: 2EXPL: 0CVE-2023-37277 – XWiki Platform vulnerable to cross-site request forgery (CSRF) via the REST API
https://notcve.org/view.php?id=CVE-2023-37277
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The REST API allows executing all actions via POST requests and accepts `text/plain`, `multipart/form-data` or `application/www-form-urlencoded` as content types which can be sent via regular HTML forms, thus allowing cross-site request forgery. With the interaction of a user with programming rights, this allows remote code execution through script macros and thus impacts the integrity, availability and confidentiality of the whole XWiki installation. For regular cookie-based authentication, the vulnerability is mitigated by SameSite cookie restrictions but as of March 2023, these are not enabled by default in Firefox and Safari. The vulnerability has been patched in XWiki 14.10.8 and 15.2 by requiring a CSRF token header for certain request types that are susceptible to CSRF attacks. • https://github.com/xwiki/xwiki-platform/commit/4c175405faa0e62437df397811c7526dfc0fbae7 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-6xxr-648m-gch6 https://jira.xwiki.org/browse/XWIKI-20135 • CWE-352: Cross-Site Request Forgery (CSRF) •
CVSS: 9.9EPSS: 0%CPEs: 5EXPL: 3CVE-2023-36468 – Upgrading doesn't prevent exploiting vulnerable XWiki documents
https://notcve.org/view.php?id=CVE-2023-36468
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. When an XWiki installation is upgraded and that upgrade contains a fix for a bug in a document, just a new version of that document is added. In some cases, it's still possible to exploit the vulnerability that was fixed in the new version. The severity of this depends on the fixed vulnerability, for the purpose of this advisory take CVE-2022-36100/GHSA-2g5c-228j-p52x as example - it is easily exploitable with just view rights and critical. When XWiki is upgraded from a version before the fix for it (e.g., 14.3) to a version including the fix (e.g., 14.4), the vulnerability can still be reproduced by adding `rev=1.1` to the URL used in the reproduction steps so remote code execution is possible even after upgrading. • https://github.com/xwiki/xwiki-platform/commit/15a6f845d8206b0ae97f37aa092ca43d4f9d6e59 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-2g5c-228j-p52x https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-8q9q-r9v2-644m https://jira.xwiki.org/browse/XWIKI-20594 • CWE-459: Incomplete Cleanup •
CVSS: 9.9EPSS: 1%CPEs: 5EXPL: 2CVE-2023-36469 – Code injection through NotificationRSSService in XWiki Platform
https://notcve.org/view.php?id=CVE-2023-36469
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user who can edit their own user profile and notification settings can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This has been patched in XWiki 14.10.6 and 15.2RC1. Users are advised to update. As a workaround the main security fix can be manually applied by patching the affected document `XWiki.Notifications.Code.NotificationRSSService`. • https://github.com/xwiki/xwiki-platform/commit/217e5bb7a657f2991b154a16ef4d5ae9c29ad39c https://github.com/xwiki/xwiki-platform/commit/217e5bb7a657f2991b154a16ef4d5ae9c29ad39c#diff-7221a548809fa2ba34348556f4b5bd436463c559ebdf691197932ee7ce4478ca https://github.com/xwiki/xwiki-platform/commit/217e5bb7a657f2991b154a16ef4d5ae9c29ad39c#diff-b261c6eac3108c3e6e734054c28a78f59d3439ab72fe8582dadf87670a0d15a4 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-94pf-92hw-2hjc https://jira.xwiki.org/browse/XWIKI-20610 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 9.9EPSS: 1%CPEs: 5EXPL: 2CVE-2023-36470 – Code injection in icon themes of XWiki Platform
https://notcve.org/view.php?id=CVE-2023-36470
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. By either creating a new or editing an existing document with an icon set, an attacker can inject XWiki syntax and Velocity code that is executed with programming rights and thus allows remote code execution. There are different attack vectors, the simplest is the Velocity code in the icon set's HTML or XWiki syntax definition. The [icon picker](https://extensions.xwiki.org/xwiki/bin/view/Extension/Icon%20Theme%20Application#HIconPicker) can be used to trigger the rendering of any icon set. The XWiki syntax variant of the icon set is also used without any escaping in some documents, allowing to inject XWiki syntax including script macros into a document that might have programming right, for this the currently used icon theme needs to be edited. • https://github.com/xwiki/xwiki-platform/commit/46b542854978e9caa687a5c2b8817b8b17877d94 https://github.com/xwiki/xwiki-platform/commit/79418dd92ca11941b46987ef881bf50424898ff4 https://github.com/xwiki/xwiki-platform/commit/b0cdfd893912baaa053d106a92e39fa1858843c7 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-fm68-j7ww-h9xf https://jira.xwiki.org/browse/XWIKI-20524 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

https://notcve.org/view.php?id=CVE-2023-35162
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the previewactions template to perform a XSS, e.g. by using URL such as: > <hostname>/xwiki/bin/get/FlamingoThemes/Cerulean xpage=xpart&vm=previewactions.vm&xcontinue=javascript:alert(document.domain). This vulnerability exists since XWiki 6.1-rc-1. The vulnerability has been patched in XWiki 14.10.5 and 15.1-rc-1. • https://github.com/xwiki/xwiki-platform/commit/9f01166b1a8ee9639666099eb5040302df067e4d https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-q9hg-9qj2-mxf9 https://jira.xwiki.org/browse/XWIKI-20342 https://jira.xwiki.org/browse/XWIKI-20583 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
