Description
An issue was discovered in Cyrus IMAP before 2.5.15, 3.0.x before 3.0.13,
and 3.1.x through 3.1.8. If sieve script uploading is allowed (3.x) or
certain non-default sieve options are enabled (2.x), a user with a mail
account on the service can use a sieve script containing a fileinto
directive to create any mailbox with administrator privileges, because of
folder mishandling in autosieve_createfolder() in imap/lmtp_sieve.c.
