CVE-2024-31464 – XWiki Platform: Password hash might be leaked by diff once the xobject holding them is deleted

https://notcve.org/view.php?id=CVE-2024-31464

XWiki Platform is a generic wiki platform. Starting in version 5.0-rc-1 and prior to versions 14.10.19, 15.5.4, and 15.9-rc-1, it is possible to access the hash of a password by using the diff feature of the history whenever the object storing the password is deleted. Using that vulnerability it's possible for an attacker to have access to the hash password of a user if they have rights to edit the users' page. With the default right scheme in XWiki this vulnerability is normally prevented on user profiles, except by users with Admin rights. Note that this vulnerability also impacts any extensions that might use passwords stored in xobjects: for those usecases it depends on the right of those pages. • https://github.com/xwiki/xwiki-platform/commit/9075668a4135cce114ef2a4b72eba3161a9e94c4 https://github.com/xwiki/xwiki-platform/commit/955fb097e02a2a7153f527522ee9eef42447e5d7 https://github.com/xwiki/xwiki-platform/commit/f1eaec1e512220fabd970d053c627e435a1652cf https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-v782-xr4w-3vqx https://jira.xwiki.org/browse/XWIKI-19948 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
