A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 9736fef3-ada6-11f1-a655-3497f65b111b advisory.

    The FreeIPA project reports:

Tenable has extracted the preceding description block directly from the FreeBSD 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 remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-3a48220f1f advisory.

    Upstream security release FreeIPA 4.13.3

The remote Fedora 44 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2026-903d904933 advisory.

    Update to Samba 4.24.6 (and rebuild of freeipa)



    ----

    This update contains no changes; it exists purely to keep the Fedora 44 freeipa package higher-versioned     than the Fedora 43 package. If it is not, upgrades of FreeIPA from Fedora 43 to 44 fail.

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