"The version of 389-ds-base installed on the remote host is prior to 1.3.10.2-17. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2025-2798 advisory.

    A denial of service vulnerability was found in 389-ds-base ldap server. This issue may allow an
    authenticated user to cause a server crash while modifying `userPassword` using malformed input.
    (CVE-2024-2199)

    A flaw was found in 389-ds-base. A specially-crafted LDAP query can potentially cause a failure on the
    directory server, leading to a denial of service (CVE-2024-3657)

    A denial of service vulnerability was found in the 389-ds-base LDAP server. This issue may allow an
    authenticated user to cause a server denial of service while attempting to log in with a user with a
    malformed hash in their password. (CVE-2024-5953)

    The fix for CVE-2024-2199 in 389-ds-base was insufficient to cover all scenarios. In certain product
    versions, an authenticated user may cause a server crash while modifying `userPassword` using malformed
    input. (CVE-2024-8445)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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