Summary

Moby is used by IBM Storage Ceph in Grafana as part of metrics. This bulletin identifies the steps to take to address the vulnerability in Grafana. CVE-2021-41089, CVE-2022-24769, CVE-2021-41091, CVE-2018-20699, CVE-2022-36109.

Vulnerability Details

CVEID:CVE-2022-36109
**DESCRIPTION:**Moby could allow a remote authenticated attacker to execute arbitrary code on the system, caused by a flaw with the supplementary groups are not set up properly. By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass primary group restrictions to execute arbitrary code or obtain sensitive information from the container.
CVSS Base score: 6.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235637 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2018-20699
**DESCRIPTION:**Docker Engine is vulnerable to a denial of service, caused by a dockerd memory consumption issue. By using a large integer in a --cpuset-mems or --cpuset-cpus value, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/155499 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2021-41091
**DESCRIPTION:**Moby could allow a local authenticated attacker to traverse directories on the system, caused by improper restricted permissions on data directory. An attacker could send a specially-crafted request containing “dot dot” sequences (/…/) to view directory contents and execute arbitrary programs.
CVSS Base score: 6.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/210711 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L)

CVEID:CVE-2022-24769
**DESCRIPTION:**Moby could allow a local attacker to gain elevated privileges on the system, caused by an issue with containers started incorrectly with non-empty inheritable Linux process capabilities. By executing specially-crafted programs, an attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/222517 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2021-41089
**DESCRIPTION:**Moby could allow a local authenticated attacker to bypass security restrictions, caused by a flaw in the docker cp command. By copying files using docker cp into a specially-crafted container, an attacker could exploit this vulnerability to change the existing Unix file permission in the host’s filesystem.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/210637 for the current score.
