CVE-2020-14316

A flaw was found in kubevirt 0.29 and earlier. Virtual Machine Instances (VMIs) can be used to gain access to the host's filesystem. Successful exploitation allows an attacker to assume the privileges of the VM process on the host system. In worst-case scenarios an attacker can read and modify any file on the system where the VMI is running. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

9.9 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
