XWiki Platform Applications Tag and XWiki Platform Tag UI vulnerable to Eval Injection

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. On XWiki versions before 13.10.4 and 14.2, this can be combined with CVE-2022-36092, meaning that no rights are required to perform the attack. The vulnerability has been patched in versions 13.10.6 and 14.4. As a workaround, the patch that fixes the issue can be manually applied to the document `Main.Tags` or the updated version of that document can be imported from version 14.4 of xwiki-platform-tag-ui using the import feature in the administration UI on XWiki 10.9 and later.

动态执行代码中指令转义处理不恰当(Eval注入)

多款 XWiki Platform 产品代码注入漏洞

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 Tag UI 13.10.6之前版本和14.4之前版本存在安全漏洞，该漏洞源于标签文档“Main.Tags”没有正确清理用户输入，这允许对文档具有查看权限的用户执行具有编程权限的任意Groovy、Python和Velocity代码，这也允许绕过所有权限检查，从而修改和披露存储在XWiki安装中的所有内容。
