"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0016 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2020-17049:
    Kerberos Security Feature Bypass Vulnerability

    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 Tencent 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.");
