Description

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).

Advisory Details

### 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:[email protected])
