| Vetor | AV:N/AC:M/Au:N/C:P/I:P/A:N |
Name of the Vulnerable Software and Affected Versions
Dovecot versions prior to 2.2.7
Description
The issue allows local users to bypass authentication and access virtual email accounts. This is achieved by attaching to the process and using a restricted file descriptor to modify account information in the response to the dovecot-auth server. The
checkpassword-reply in Dovecot performs setuid operations to a user who is authenticating.Recommendations
For versions prior to 2.2.7, update to version 2.2.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the
checkpassword-reply functionality until a patch is available.Correção
Improper Authentication
