20. Aviatrix Controller and Gateways - Privilege Escalation¶
Date 02/03/2022
Risk Rating Medium
Description The publicly disclosed CVE-2021-4034 and CVE-2022-0185 are local privilege escalation vulnerabilities disclosed in the past two weeks. When successfully executed, an attack exploiting these vulnerabilities can cause a local privilege escalation giving unprivileged users administrative rights on the target machine. The Aviatrix Gateway, Controller, and Copilot are all running vulnerable versions of the Linux packages. However, in order to successfully exploit these vulnerabilities, an attacker requires local access to our systems and no vulnerability known to us today would allow such attack.
Impact A local user to our appliances can escalate his privileges to root.
Affected Products Aviatrix Controller and Gateways.
- Solution
- Upgrade Copilot to Release 1.6.3.
- Apply security patch [AVI-2022-0001 - CVE-2021-4034 and CVE-2022-0185 Privilege Escalation Patches] to controllers.
