medium Nessus Plugin ID 160774


The remote NewStart CGSL host is affected by multiple vulnerabilities.


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

- An issue was discovered in Dovecot before 2.3.13. By using IMAP IDLE, an authenticated attacker can trigger unhibernation via attacker-controlled parameters, leading to access to other users' email messages (and path disclosure). (CVE-2020-24386)

- Dovecot before 2.3.13 has Improper Input Validation in lda, lmtp, and imap, leading to an application crash via a crafted email message with certain choices for ten thousand MIME parts. (CVE-2020-25275)

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


Upgrade the vulnerable CGSL dovecot packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
