"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2022:0094 advisory.

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

    CVE-2019-3816:
    Openwsman, versions up to and including 2.6.9, are vulnerable to arbitrary file disclosure because the
    working directory of openwsmand daemon was set to root directory. A remote, unauthenticated attacker can
    exploit this vulnerability by sending a specially crafted HTTP request to openwsman server.

    CVE-2019-3833:
    Openwsman, versions up to and including 2.6.9, are vulnerable to infinite loop in process_connection()
    when parsing specially crafted HTTP requests. A remote, unauthenticated attacker can exploit this
    vulnerability by sending malicious HTTP request to cause denial of service to openwsman server.

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.");
