Ubuntu 20.04 LTS : Ceph vulnerabilities (USN-4706-1)

high Nessus Plugin ID 145517

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4706-1 advisory.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
