"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0022 advisory.

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

    CVE-2020-17049:
    <p>A security feature bypass vulnerability exists in the way Key Distribution Center (KDC) determines if a
    service ticket can be used for delegation via Kerberos Constrained Delegation (KCD).</p>
    <p>To exploit the vulnerability, a compromised service that is configured to use KCD could tamper with a
    service ticket that is not valid for delegation to force the KDC to accept it.</p>
    <p>The update addresses this vulnerability by changing how the KDC validates service tickets used with
    KCD.</p>

    CVE-2023-5455:
    A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions
    of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform
    actions as the user, resulting in a loss of confidentiality and system integrity. During community
    penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection.
    Due to implementation details one cannot use this flaw for reflection of a cookie representing already
    logged-in user. An attacker would always have to go through a new authentication attempt.

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.");
