Kea configuration and API directives can be used to overwrite arbitrary files, subject to permissions granted to Kea. Many common configurations run Kea as root, leave the API entry points unsecured by default, and/or place the control sockets in insecure paths. This issue affects Kea versions 2.4.0 through 2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8.

The remote AlmaLinux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2025:9178 advisory.

    * kea: Loading a malicious hook library can lead to local privilege escalation (CVE-2025-32801)
      * kea: Insecure handling of file paths allows multiple local attacks (CVE-2025-32802)
      * kea: Insecure file permissions can result in confidential information leakage (CVE-2025-32803)

Tenable has extracted the preceding description block directly from the AlmaLinux 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.

  - Kea configuration and API directives can be used to overwrite arbitrary files, subject to permissions     granted to Kea. Many common configurations run Kea as root, leave the API entry points unsecured by     default, and/or place the control sockets in insecure paths. This issue affects Kea versions 2.4.0 through     2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8. (CVE-2025-32802)

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

The remote Oracle Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2025-9178 advisory.

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-dc6ec0a8e2 advisory.

    - New version 2.6.3 (rhbz#2368989)
    - Fix for: CVE-2025-32801, CVE-2025-32802, CVE-2025-32803
    - kea.conf: Remove /tmp/ from socket-name for existing configurations
    - kea.conf: Set pseudo-random password for default config to secure fresh install and allow CA startup     without user intervention
    - kea.conf: Restrict directory permissions
    - Sync service files with upstream
    - Fix leases ownership when switching from root to kea user (rhbz#2324168)

    Release Notes:

    The new default configuration file, kea-ctrl-agent.conf, introduces an authentication setting, password-     file, which restricts access to the REST API. On Fedora, the kea-api-password file is automatically     populated with a pseudo-random password to secure new installations.

    For system upgrades, it is strongly recommended to update any custom configurations to restrict access to     the REST API.

    For more details, including information on CVE fixes and incompatible changes, refer to the upstream     release notes:
