CVSS: 9.6EPSS: 0%CPEs: 3EXPL: 0CVE-2022-41937 – Missing Authorization in XWiki Platform
https://notcve.org/view.php?id=CVE-2022-41937
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The application allows anyone with view access to modify any page of the wiki by importing a crafted XAR package. The problem has been patched in XWiki 14.6RC1, 14.6 and 13.10.8. As a workaround, setting the right of the page Filter.WebHome and making sure only the main wiki administrators can view the application installed on main wiki or edit the page and apply the changed described in commit fb49b4f. XWiki Platform es una plataforma wiki genérica que ofrece servicios de ejecución para aplicaciones creadas sobre ella. • https://github.com/xwiki/xwiki-platform/commit/fb49b4f289ee28e45cfada8e97e320cd3ed27113 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-q6jp-gcww-8v2j https://jira.xwiki.org/browse/XWIKI-19758 • CWE-862: Missing Authorization •
CVSS: 9.1EPSS: 0%CPEs: 1EXPL: 0CVE-2022-39387 – XWiki OIDC Authenticator vulnerable to OpenID login bypass due to improper authentication
https://notcve.org/view.php?id=CVE-2022-39387
XWiki OIDC has various tools to manipulate OpenID Connect protocol in XWiki. Prior to version 1.29.1, even if a wiki has an OpenID provider configured through its xwiki.properties, it is possible to provide a third party provider its details through request parameters. One can then bypass the XWiki authentication altogether by specifying its own provider through the oidc.endpoint.* request parameters (or by using an XWiki-based OpenID provider with oidc.xwikiprovider. With the same approach, one could also provide a specific group mapping through oidc.groups.mapping that would make his user automatically part of the XWikiAdminGroup. This issue has been patched, please upgrade to 1.29.1. • https://github.com/xwiki-contrib/oidc/commit/0247af1417925b9734ab106ad7cd934ee870ac89 https://github.com/xwiki-contrib/oidc/security/advisories/GHSA-m7gv-v8xx-v47w https://jira.xwiki.org/browse/OIDC-118 • CWE-287: Improper Authentication •
CVSS: 9.9EPSS: 0%CPEs: 2EXPL: 2CVE-2022-36100 – XWiki Platform Applications Tag and XWiki Platform Tag UI vulnerable to Eval Injection
https://notcve.org/view.php?id=CVE-2022-36100
XWiki Platform Applications Tag and XWiki Platform Tag UI are tag applications for XWiki, a generic wiki platform. Starting with version 1.7 in XWiki Platform Applications Tag and prior to 13.10.6 and 14.4 in XWiki Platform Tag UI, the tags document `Main.Tags` in XWiki didn't sanitize user inputs properly. This allowed users with view rights on the document (default in a public wiki or for authenticated users on private wikis) to execute arbitrary Groovy, Python and Velocity code with programming rights. This also allowed bypassing all rights checks and thus both modification and disclosure of all content stored in the XWiki installation. The vulnerability could be used to impact the availability of the wiki. • https://github.com/xwiki/xwiki-platform/commit/604868033ebd191cf2d1e94db336f0c4d9096427 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-2g5c-228j-p52x https://jira.xwiki.org/browse/XWIKI-19747 • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') CWE-116: Improper Encoding or Escaping of Output •

https://notcve.org/view.php?id=CVE-2022-36098
XWiki Platform Mentions UI is a user interface for mentioning users in wiki content for XWiki Platform, a generic wiki platform. Starting in version 12.5-rc-1 and prior to versions 13.10.6 and 14.4, it's possible to store Javascript or groovy scripts in a mention, macro anchor, or reference field. The stored code is executed by anyone visiting the page with the mention. This issue has been patched on XWiki 14.4 and 13.10.6. As a workaround, one may update `XWiki.Mentions.MentionsMacro` and edit the `Macro code` field of the `XWiki.WikiMacroClass` XObject. • https://github.com/xwiki/xwiki-platform/commit/4032dc896857597efd169966dc9e2752a9fdd459#diff-4fe22885f772e47d3561a05348f73921669ec12d4413b220383b73c7ae484bc4R608-R610 https://github.com/xwiki/xwiki-platform/commit/4f290d87a8355e967378a1ed6aee23a06ba162eb https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-c5v8-2q4r-5w9v https://jira.xwiki.org/browse/XWIKI-19752 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

https://notcve.org/view.php?id=CVE-2022-36099
XWiki Platform Wiki UI Main Wiki is software for managing subwikis on XWiki Platform, a generic wiki platform. Starting with version 5.3-milestone-2 and prior to versions 13.10.6 and 14.4, it's possible to inject arbitrary wiki syntax including Groovy, Python and Velocity script macros via the request (URL parameter) using the `XWikiServerClassSheet` if the user has view access to this sheet and another page that has been saved with programming rights, a standard condition on a public read-only XWiki installation or a private XWiki installation where the user has an account. This allows arbitrary Groovy/Python/Velocity code execution which allows bypassing all rights checks and thus both modification and disclosure of all content stored in the XWiki installation. Also, this could be used to impact the availability of the wiki. This has been patched in versions 13.10.6 and 14.4. • https://github.com/xwiki/xwiki-platform/commit/fc77f9f53bc65a4a9bfae3d5686615309c0c76cc https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-xr6m-2p4m-jvqf https://jira.xwiki.org/browse/XWIKI-19746 • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') CWE-116: Improper Encoding or Escaping of Output •
