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.

cyrus-imapd: lmtpd component created mailboxes with administrator privileges if the "fileinto" was used, bypassing ACL checks
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.
Mitigation: This flaw can be mitigated by:
1. In cyrus-imapd >= 2.5 disable anysievefolder (it is disabled by default)
2. In cyrus-imapd >=3.0 disable sieve_extensions
Package: cyrus-imapd (Red Hat Enterprise Linux 5) - Out of support scope
