Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU67071

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1798

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote user to read arbitrary files on the system.

The vulnerability exists due to a logic issue in kubeVirt API. A remote user can use the kubeVirt API to provide access to host files (like /etc/passwd, for example) in a KubeVirt VM as a disk device that can be written to and read from.

Mitigation

Update the affected package kubevirt, virt-api-container, virt-controller-container, virt-handler-container, virt-launcher-container, virt-libguestfs-tools-container, virt-operator-container to the latest version.

2) Overly permissive cross-domain whitelist

EUVDB-ID: #VU66447

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1996

CWE-ID: CWE-942 - Overly Permissive Cross-domain Whitelist

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass the CORS protection mechanism.

The vulnerability exists due to incorrect processing of the "Origin" HTTP header that is supplied within HTTP request. A remote attacker can supply arbitrary value via the "Origin" HTTP header, bypass implemented CORS protection mechanism and perform cross-site scripting attacks against the vulnerable application.

3) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU63090

Risk: Medium

CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-29162

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to containers are incorrectly started with non-empty inheritable Linux process capabilities, which leads to security restrictions bypass and privilege escalation.
