Ceph is a distributed object, block, and file storage platform. In versions 17.2.7, 18.2.1 through 18.2.4, and 19.0.0 through 19.2.2, an unprivileged user can escalate to root privileges in a ceph-fuse mounted CephFS by chmod 777 a directory owned by root to gain access. The result of this is that a user could read, write and execute to any directory owned by root as long as they chmod 777 it. This impacts confidentiality, integrity, and availability. It is patched in versions 17.2.8, 18.2.5, and 19.2.3.

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:1536 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.

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.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4310 advisory.

    Ceph a distributed filesystem was affected by multiple vulnerabilties

    CVE-2021-3979

        A key length flaw was found in Ceph Storage component.
        An attacker can exploit the fact that the key length is incorrectly         passed in an encryption algorithm to create a non random key,         which is weaker and can be exploited for loss of confidentiality         and integrity on encrypted disks.

    CVE-2022-3650

        A privilege escalation flaw was found in Ceph. Ceph-crash.service allows         a local attacker to escalate privileges to root in the form of a crash         dump, and dump privileged information.

    CVE-2023-43040

        A flaw was found in Ceph RGW. An unprivileged         user can write to any bucket(s) accessible by a given key         if a POST's form-data contains a key called 'bucket'         with a value matching the name of the bucket used to sign         the request. The result of this is that a user could actually         upload to any bucket accessible by the specified access key         as long as the bucket in the POST policy matches the bucket         in said POST form part.

    CVE-2025-52555

        An unprivileged user can escalate to root privileges         in a ceph-fuse mounted CephFS by chmod 777 a directory owned         by root to gain access. The result of this is that a user could         read, write and execute to any directory owned by root as long         as they chmod 777 it. This impacts confidentiality,         integrity, and availability.

    For Debian 11 bullseye, these problems have been fixed in version     14.2.21-1+deb11u1.

    We recommend that you upgrade your ceph packages.
