    (CVE-2021-42096)

  - GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrf_token value is not specific to a     single user account. An attacker can obtain a value within the context of an unprivileged user account,     and then use that value in a CSRF attack against an admin (e.g., for account takeover). (CVE-2021-42097)

    (CVE-2021-42096)

  - In GNU Mailman before 2.1.36, a crafted URL to the Cgi/options.py 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.py 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)

  - In GNU Mailman before 2.1.38, a list member or moderator can get a CSRF token and craft an admin request     (using that token) to set a new admin password or make other changes. (CVE-2021-44227)

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5121-2 advisory.

  - /options/mailman in GNU Mailman before 2.1.31 allows Arbitrary Content Injection. (CVE-2020-12108)

  - GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts.
    This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an     archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the     MIME type should have been text/html, and execute JavaScript code. (CVE-2020-12137)

Mark Sapiro reports :

A potential for for a list member to carry out an off-line brute-force attack to obtain the list admin password has been reported by Andre Protas, Richard Cloke and Andy Nuttall of Apple. This is fixed.

A CSRF attack via the user options page could allow takeover of a users account. This is fixed.
