Amazon Linux 2 : mailman (ALAS-2023-2370)

medium Nessus Plugin ID 186562


The remote Amazon Linux 2 host is missing a security update.


The version of mailman installed on the remote host is prior to 2.1.15-30. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2370 advisory.

- In GNU Mailman before 2.1.36, a crafted URL to the Cgi/ user options page can execute arbitrary JavaScript for XSS. (CVE-2021-43331)

- In GNU Mailman before 2.1.36, the CSRF token for the Cgi/ admindb page contains an encrypted version of the list admin password. This could potentially be cracked by a moderator via an offline brute- force attack. (CVE-2021-43332)

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


Run 'yum update mailman' to update your system.
