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.
