Vulnerability Name:

CVE-2018-9846 (CCN-141392)

Assigned:2018-04-07
Published:2018-04-07
Updated:2018-05-24
Summary:In Roundcube from versions 1.2.0 to 1.3.5, with the archive plugin enabled and configured, it's possible to exploit the unsanitized, user-controlled "_uid" parameter (in an archive.php _task=mail&_mbox=INBOX&_action=plugin.move2archive request) to perform an MX (IMAP) injection attack by placing an IMAP command after a %0d%0a sequence.
Note: this is less easily exploitable in 1.3.4 and later because of a Same Origin Policy protection mechanism.
