Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Ametys versions prior to 4.0.3

Description The issue allows remote attackers to bypass intended access restrictions. This can be achieved by making a direct request to "/plugins/core-ui/servercomm/messages.xml". Attackers can exploit this by obtaining account details via a "users/search.json" request and then modifying the account via an "editUser" request.

Recommendations For Ametys versions prior to 4.0.3, update to version 4.0.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the "/plugins/core-ui/servercomm/messages.xml" endpoint and limiting the use of "users/search.json" and "editUser" requests until a patch is applied.
