In Open-iSCSI tcmu-runner 1.3.x, 1.4.x, and 1.5.x through 1.5.2, xcopy_locate_udev in tcmur_cmd_handler.c lacks a check for transport-layer restrictions, allowing remote attackers to read or write files via directory traversal in an XCOPY request. For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. NOTE: relative to CVE-2020-28374, this is a similar mistake in a different algorithm.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1518 advisory.

    Red Hat Ceph Storage is a scalable, open, software-defined storage platform that combines the most stable     version of the Ceph storage system with a Ceph management platform, deployment utilities, and support     services.

    The ceph-ansible package provides Ansible playbooks for installing, maintaining, and upgrading Red Hat     Ceph Storage.

    Grafana is an open source, feature rich metrics dashboard and graph editor for Graphite, InfluxDB &     OpenTSDB.

    The tcmu-runner packages provide a service that handles the complexity of the LIO kernel target's     userspace passthrough interface (TCMU). It presents a C plugin API for extension modules that handle SCSI     requests in ways not possible or suitable to be handled by LIO's in-kernel backstores.

    Security Fix(es):

    * grafana: SSRF incorrect access control vulnerability allows unauthenticated users to make grafana send     HTTP requests to any URL (CVE-2020-13379)

    * ceph: User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila     (CVE-2020-27781)

    * tcmu-runner: SCSI target (LIO) write to any block on ILO backstore (CVE-2021-3139)

    * ceph: specially crafted XML payload on POST requests leads to DoS by crashing RGW (CVE-2020-12059)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    This advisory fixes the following bug:

    * When rebooting OSDs, the `_OSD down_` tab in the `_CEPH Backend storage_` dashboard shows the correct     number of OSDs that is `down`. However, when all OSDs are `up` again after the reboot, the tab continues     showing the number of `down` OSDs. With this update, both CLI and Grafana values are matching during osd     up/down operation and working as expected. (BZ#1652233)

    All users of Red Hat Ceph Storage are advised to upgrade to these updated packages.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.
