A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the client’s session key. This key is different for each new session, which protects it from brute force attacks. However, the ticket it contains is encrypted using the target principal key directly. For user principals, this key is a hash of a public per-principal randomly-generated salt and the user’s password. If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any principal, all of them being encrypted by their own key directly. By taking these tickets and salts offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when combined to a principal salt (i.e. find the principal’s password).

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0152 advisory.

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

    CVE-2024-2698:
    A vulnerability was found in FreeIPA in how the initial implementation of MS-SFU by MIT Kerberos was     missing a condition for granting the forwardable flag on S4U2Self tickets. Fixing this mistake required     adding a special case for the check_allowed_to_delegate() function: If the target service argument is     NULL, then it means the KDC is probing for general constrained delegation rules and not checking a     specific S4U2Proxy request.
    In FreeIPA 4.11.0, the behavior of ipadb_match_acl() was modified to match the changes from upstream MIT     Kerberos 1.20. However, a mistake resulting in this mechanism applies in cases where the target service     argument is set AND where it is unset. This results in S4U2Proxy requests being accepted regardless of     whether or not there is a matching service delegation rule.

    CVE-2024-3183:
    A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the clients     session key. This key is different for each new session, which protects it from brute force attacks.
    However, the ticket it contains is encrypted using the target principal key directly. For user principals,     this key is a hash of a public per-principal randomly-generated salt and the users password.
    If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any     principal, all of them being encrypted by their own key directly. By taking these tickets and salts     offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when     combined to a principal salt (i.e. find the principals password).

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the client's     session key. This key is different for each new session, which protects it from brute force attacks.
    However, the ticket it contains is encrypted using the target principal key directly.

(CVE-2024-3183)

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2585 advisory.
