  - OpenStack Ironic through before 35.0.2 allows file overwrite via directory traversal during deployment
    with a crafted ISO image. (CVE-2026-48681)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8421-1 advisory.

    Dmitry Tantsur and Tuomo Tanskanen discovered that Ironic did not properly validate file paths when     handling ISO images. A privileged authenticated remote user could use this issue to perform path traversal     via a crafted ISO image and overwrite arbitrary files on the Ironic conductor. (CVE-2026-48681)

    Dmitry Tantsur and Tuomo Tanskanen discovered that Ironic did not properly validate kernel command line     parameters. A privileged authenticated remote user could use this issue to inject scripts during node boot     and possibly execute arbitrary code. (CVE-2026-46447)

    Dmitry Tantsur and Tuomo Tanskanen discovered that Ironic incorrectly restricted access to custom PXE     templates. A privileged authenticated remote user could use this issue to read arbitrary sensitive files     on the Ironic conductor. (CVE-2026-44917)

Tenable has extracted the preceding description block directly from the Ubuntu 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 Debian 12 / 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6341 advisory.

    Multiple security vulnerabilities were discovered in Ironic, the     OpenStack component to manage and provision baremetal servers, which     could result in information disclosure or denial of service.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 1:21.4.4-0+deb12u1. In addition python-oslo.messaging needed     to be updated to 14.0.3-0+deb12u1.

    For the stable distribution (trixie), these problems have been fixed in     version 1:29.0.5-0+deb13u2. In addition python-oslo.messaging needed     to be updated to 16.1.0-3+deb13u1.

    We recommend that you upgrade your ironic packages.
