CVE-2022-29178
CVSS v3.1
8.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Cilium versions prior to 1.9.16
Cilium versions prior to 1.10.11
Cilium versions prior to 1.11.5
Description
Cilium is open source software for providing and securing network connectivity and loadbalancing between application workloads. It contains an incorrect default permissions vulnerability, allowing operating systems with users belonging to the group ID 1000 to access the API of Cilium via Unix domain socket available on the host where Cilium is running. This could allow malicious users to compromise integrity as well as system availability on that host.
Recommendations
For versions prior to 1.9.16, update to version 1.9.16 or later.
For versions prior to 1.10.11, update to version 1.10.11 or later.
For versions prior to 1.11.5, update to version 1.11.5 or later.
As a temporary workaround, modify Cilium's DaemonSet to run with a certain command, which can be found in the GitHub Security Advisory for this vulnerability.
Prevent Cilium from running with group 1000 by modifying Cilium's DaemonSet to run with the following command:
containers:
- name: cilium-agent
args:
- -c
- "groupdel cilium && cilium-agent --config-dir=/tmp/cilium/config-map"
command:
- bashExploit
