CVE-2018-1128
Description
It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to the ceph cluster network who is also able to sniff packets on the network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service.
Statement
Red Hat OpenStack Platform ships the flawed package, however RHOSP deployments use the ceph package directly from the Ceph channel. A RHOSP ceph update will therefore not be provided at this time, but please ensure that the underlying Red Hat Ceph Storage is updated.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
