Ceph

A flaw was found in Openstack manilla owning a Ceph File system "share", which enables the owner to read/write any manilla share or entire file system. The vulnerability is due to a bug in the "volumes" plugin in Ceph Manager. This allows an attacker to compromise…

It was found that ceph-isci-cli package as shipped by Red Hat Ceph Storage 2 and 3 is using python-werkzeug in debug shell mode. This is done by setting debug=True in file /usr/bin/rbd-target-api provided by ceph-isci-cli package. This allows unauthenticated attackers to access…

In the Linux kernel, the following vulnerability has been resolved: ceph: bound copied dentry name length in NFS export get_name ceph_get_name() copies the MDS-supplied name into the caller's NAME_MAX-sized buffer with memcpy(name, rinfo->dname, rinfo->dname_len) and then…

A flaw was found in the ceph-ansible playbook where it contained hardcoded passwords that were being used as default passwords while deploying Ceph services. Any authenticated attacker can abuse this flaw to brute-force Ceph deployments, and gain administrator access to Ceph…

A flaw was found in the Cephx authentication protocol in versions before 15.2.6 and before 14.2.14, where it does not verify Ceph clients correctly and is then vulnerable to replay attacks in Nautilus. This flaw allows an attacker with access to the Ceph cluster network to…

Ceph is a distributed object, block, and file storage platform. In versions 19.2.3 and below, it is possible to send an JWT that has "none" as JWT alg. And by doing so the JWT signature is not checked. The vulnerability is most likely in the RadosGW OIDC provider. As of time of…

A flaw was found in the way ceph mon handles user requests. Any authenticated ceph user having read access to ceph can delete, create ceph storage pools and corrupt snapshot images. Ceph branches master, mimic, luminous and jewel are believed to be affected.

In the Linux kernel, the following vulnerability has been resolved: ceph: bound num_export_targets array for mds info v2/v3 ceph_mdsmap_decode() in fs/ceph/mdsmap.c reads num_export_targets from each per-mds info record and advances the decode cursor by num_export_targets *…

Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the Monitor subscription handler fails to properly authorize access to the configuration-key store, allowing any CephX user with only  `mon…

An authorization bypass vulnerability was found in Ceph versions 15.2.0 before 15.2.2, where the ceph-mon and ceph-mgr daemons do not properly restrict access, resulting in gaining access to unauthorized resources. This flaw allows an authenticated client to modify the…

Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the CephX authentication protocol encrypts tickets with AES-128-CBC in an unauthenticated mode that uses a hard-coded initialization vector and…

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.

Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the RADOS Gateway (RGW) protects STS session tokens with an AES-128-CBC handler that provides no message authentication, allowing an attacker…

In the Linux kernel, the following vulnerability has been resolved: ceph: fix multifs mds auth caps issue The mds auth caps check should also validate the fsname along with the associated caps. Not doing so would result in applying the mds auth caps of one fs on to the other…

Ceph is a distributed object, block, and file storage platform. In versions up to and including 19.2.3, using the argument `x-amz-copy-source` to put an object and specifying an empty string as its content leads to the RGW daemon crashing, resulting in a DoS attack. As of time…

An issue was discovered in Ceph through 13.2.9. A POST request with an invalid tagging XML can crash the RGW process by triggering a NULL pointer exception.

A path traversal flaw was found in the Ceph dashboard implemented in upstream versions v14.2.5, v14.2.6, v15.0.0 of Ceph storage and has been fixed in versions 14.2.7 and 15.1.0. An unauthenticated attacker could use this flaw to cause information disclosure on the host machine…

A flaw was found in the Ceph RGW configuration with Beast as the front end handling client requests. An unauthenticated attacker could crash the Ceph RGW server by sending valid HTTP headers and terminating the connection, resulting in a remote denial of service for Ceph RGW…

A flaw was found in the way civetweb frontend was handling requests for ceph RGW server with SSL enabled. An unauthenticated attacker could create multiple connections to ceph RADOS gateway to exhaust file descriptors for ceph-radosgw service resulting in a remote denial of…

It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and…
