CVE-2023-34465: Mail.MailConfig can be edited by any user with edit rights
XWiki Platform is a generic wiki platform. Starting in version 11.8-rc-1 and prior to versions 14.4.8, 14.10.6, and 15.2, Mail.MailConfig can be edited by any logged-in user by default. Consequently, they can change the mail obfuscation configuration and view and edit the mail sending configuration, including the smtp domain name and credentials. The problem has been patched in XWiki 14.4.8, 14.10.6, and 15.1. As a workaround, the rights of the Mail.MailConfig page can be manually updated so that only a set of trusted users can view, edit and delete it (e.g., the XWiki.XWikiAdminGroup group).

Description
Mail.MailConfig is expected to be editable by admins only as it contains some configurations (e.g., the obfuscation of mails). But currently, there is no restrictions and it can be edited by any user with edit rights.
Mail.SendMailConfigClass in Mail.MailConfig can also be edited in the same way, allowing any user to redirect send mail to a rogue smtp server, allowing the received all emitted mails.

### Impact `Mail.MailConfig` can be edited by any logged-in user by default. Consequently, they can: - change the mail obfuscation configuration - view and edit the mail sending configuration, including the smtp domain name and credentials. ### Patches The problem has been patched on XWiki 14.4.8, 15.1, and 14.10.6. ### Workarounds The rights of the `Mail.MailConfig` page can be manually updated so that only a set of trusted users can view, edit and delete it (e.g., the `XWiki.XWikiAdminGroup` group). On 14.4.8+, 15.1-rc-1+, or 14.10.5+, if at startup `Mail.MailConfig` does not have any rights defined, `view`, `edit ` and `delete` rights are automatically granted to the `XWiki.XWikiAdminGroup` group. See the corresponding [patch](https://github.com/xwiki/xwiki-platform/commit/d28d7739089e1ae8961257d9da7135d1a01cb7d4). ### References - https://jira.xwiki.org/browse/XWIKI-20519 + https://jira.xwiki.org/browse/XWIKI-20671 - https://github.com/xwiki/xwiki-platform/commit/d28d7739089e1a...
