The remote NewStart CGSL host, running version MAIN 6.02, has cyrus-imapd packages installed that are affected by multiple vulnerabilities:

  - Cyrus IMAP 2.5.x before 2.5.14 and 3.x before 3.0.12 allows privilege escalation because an HTTP request     may be interpreted in the authentication context of an unrelated previous request that arrived over the     same connection. (CVE-2019-18928)

  - 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. (CVE-2019-19783)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Update to version 3.0.12 of cyrus-imapd, which includes (among other fixes) a fix for CVE-2019-18928.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3052 advisory.

  - Cyrus IMAP 2.5.x before 2.5.14 and 3.x before 3.0.12 allows privilege escalation because an HTTP request     may be interpreted in the authentication context of an unrelated previous request that arrived over the     same connection. (CVE-2019-18928)

  - Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of service (multiple-minute daemon hang)     via input that is mishandled during hash-table interaction. Because there are many insertions into a     single bucket, strcmp becomes slow. This is fixed in 3.4.2, 3.2.8, and 3.0.16. (CVE-2021-33582)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
