Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Summary
### Impact It's possible to know if a user has or not an account in a wiki related to an email address, and which username(s) is actually tied to that email by forging a request to the Forgot username page. Note that since this page does not have a CSRF check it's quite easy to perform a lot of those requests. ### Patches This issue has been patched in XWiki 12.10.5 and 13.2RC1. Two different patches are provided: - a first one to fix the CSRF problem - a more complex one that now relies on sending an email for the Forgot username process. ### Workarounds It's possible to fix the problem without uprading by editing the ForgotUsername page in version below 13.x, to use the following code: https://github.com/xwiki/xwiki-platform/blob/69548c0320cbd772540cf4668743e69f879812cf/xwiki-platform-core/xwiki-platform-administration/xwiki-platform-administration-ui/src/main/resources/XWiki/ForgotUsername.xml#L39-L123 In version after 13.x it's also possible to edit manually the forgotusername.vm file, but it's really encouraged to upgrade the version here. ### References * https://jira.xwiki.org/browse/XWIKI-18384 * https://jira.xwiki.org/browse/XWIKI-18408 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki](https://jira.xwiki.org) * Email us at [security ML](mailto:security@xwiki.org)

      "value": "### Impacto Es posible saber si un usuario presenta o no una cuenta en un wiki relacionada con una direcci\u00f3n de correo electr\u00f3nico, y qu\u00e9 nombre(s) de usuario est\u00e1(n) realmente vinculado(s) a ese correo electr\u00f3nico al falsificar una petici\u00f3n a la p\u00e1gina de Nombre de usuario olvidado. Ten en cuenta que como esta p\u00e1gina no presenta una comprobaci\u00f3n de tipo CSRF es bastante f\u00e1cil llevar a cabo muchas de esas peticiones. ### Parches Este problema ha sido parcheado en XWiki versiones 12.10.5 y 13.2RC1. Se proporcionan dos parches diferentes: - uno para corregir el problema de CSRF - otro m\u00e1s complejo que ahora es basado en el env\u00edo de un correo electr\u00f3nico para el proceso Forgot username. ### Mitigaciones Es posible arreglar el problema sin actualizar al editar la p\u00e1gina de ForgotUsername en versiones anteriores a 13.x, para usar el siguiente c\u00f3digo: https://github.com/xwiki/xwiki-platform/blob/69548c0320cbd772540cf4668743e69f879812cf/xwiki-platform-core/xwiki-platform-administration/xwiki-platform-administration-ui/src/main/resources/XWiki/ForgotUsername.xml#L39-L123 En la versi\u00f3n posterior a 13.x tambi\u00e9n es posible editar manualmente el archivo forgotusername.vm, pero es recomendado actualizar la versi\u00f3n aqu\u00ed.
