AlmaLinux 8 : idm:DL1 (ALSA-2024:0143)

medium Nessus Plugin ID 188006


The remote AlmaLinux host is missing one or more security updates.


The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2024:0143 advisory.

- <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-2020-17049)

- 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. (CVE-2023-5455)

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