"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2022:0093 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

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

    CVE-2020-12137:
    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-2020-15011:
    GNU Mailman before 2.1.33 allows arbitrary content injection via the Cgi/private.py private archive login
    page.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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