CRITICAL

XWiki Platform's Mail.MailConfig can be edited by any user with edit rights

Published June 20, 2023Updated November 8, 2023Source: osv

Summary

### 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/d28d7739089e1ae8961257d9da7135d1a01cb7d4 - https://github.com/xwiki/xwiki-platform/commit/8910b8857d3442d2e8142f655fdc0512930354d1 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:security@xwiki.org)
