CVE-2022-36099— XWiki Platform 代码注入漏洞

XWiki Platform Wiki UI Main Wiki Eval Injection vulnerability

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. As a workaround, edit the affected document `XWiki.XWikiServerClassSheet` or `WikiManager.XWikiServerClassSheet` and manually perform the changes from the patch fixing the issue. On XWiki versions 12.0 and later, it is also possible to import the document `XWiki.XWikiServerClassSheet` from the xwiki-platform-wiki-ui-mainwiki package version 14.4 using the import feature of the administration application as there have been no other changes to this document since XWiki 12.0.

XWiki Platform 代码注入漏洞

XWiki Platform是法国XWiki公司的一套用于创建Web协作应用程序的Wiki平台。 XWiki Platform 13.10.6之前版本和14.4之前版本存在安全漏洞，该漏洞源于如果用户有视图，可以使用“XWikiServerClassSheet”通过请求URL参数注入任意wiki语法，包括 Groovy、Python和Velocity脚本访问此工作表和另一个以编程权限保存的页面。这允许执行任意Groovy/Python/Velocity代码，从而绕过所有权限检查，进而修改和披露存储在XWi
