CVE-2022-32294: 
Zimbra Collaboration Server vulnerability analysis and mitigation

Zimbra Collaboration Open Source 8.8.15 was reported to have a security issue where the initial-login randomly created password (from the "zmprov ca" command) is not encrypted and is visible in cleartext on port UDP 514 (syslog port). However, this vulnerability is disputed as third parties have reported that they cannot reproduce the issue (NVD).

The vulnerability was initially reported to affect the "zmprov ca" command in Zimbra Collaboration 8.8.15. According to the report, when a user is created using this command, a random password is generated. The concern was that this password could be visible in cleartext format in syslog messages on UDP port 514 with the format "COMMAND=zimbra/zmprov ca username and password". The CVSS v3.1 base score assigned was 7.5 HIGH with vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (NVD).

If the vulnerability were valid, it could potentially allow attackers to intercept initial passwords of newly created accounts by monitoring syslog traffic on UDP port 514. This could lead to unauthorized access to user accounts during their initial setup phase.

Given that the vulnerability is disputed and could not be reproduced by third parties, no specific mitigations have been published. However, as a general security practice, administrators should ensure that syslog traffic is properly secured and that users change their initial passwords upon first login.
