CVE-2021-32732
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.
Does this matter?
Lower severity and a low EPSS score (0.96%). Track it; it rarely justifies an emergency change on its own.
Description
### 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)
