Get in Touch
Cisco has released a patch to address several vulnerabilities in their NFV Infrastructure Software (NFVIS).
Two of these, (CVE-2022-20777, 2022-20779) could allow attackers to execute code on the host machine and another (CVE-2022-20780) could be used to leak system data.
An authenticated, remote attacker could escape from the guest virtual machine (VM) to gain unauthorised root-level access on the NFVIS host.
Cisco Enterprise NFVIS before 4.7.1.
