USN-4706-1: Ceph vulnerabilities

First published: Thu Jan 28 2021(Updated: )

Olle Segerdahl found that ceph-mon and ceph-mgr daemons did not properly restrict access, resulting in gaining access to unauthorized resources. An authenticated user could use this vulnerability to modify the configuration and possibly conduct further attacks. (CVE-2020-10736) Adam Mohammed found that Ceph Object Gateway was vulnerable to HTTP header injection via a CORS ExposeHeader tag. An attacker could use this to gain access or cause a crash. (CVE-2020-10753) Ilya Dryomov found that Cephx authentication did not verify Ceph clients correctly and was then vulnerable to replay attacks in Nautilus. An attacker could use the Ceph cluster network to authenticate via a packet sniffer and perform actions. This issue is a reintroduction of CVE-2018-1128. (CVE-2020-25660)
