The full list of affected devices is available on the Lenovo support website. The vulnerabilities affect several Lenovo device families, including Lenovo IdeaPad 3, Flex 3, 元40, Legion 5 and 7, Legion Y540, S14, S145, S540, Slim 7 and 9, V14 and V15, and Yoga Slim 7 devices. It appears that Lenovo did not deactivate these properly in production devices. we we check for updates it gives an error " Unable to connect to the Update Content Server.".Lenovo reveals on the website that several of its notebook devices are affected by three different vulnerabilities - CVE-2021-3970, CVE-2021-3971, and CVE-2021-3972 - that could allow attackers with elevated privileges to execute arbitrary code or disable SPI flash protections during the operating system runtime.ĮSET, the security company that discovered the vulnerabilities and reported them to Lenovo, discovered that two of the vulnerabilities affect UEFI firmware drivers that were meant only for use in the manufacturing process. It could a a deny policy, or Authentication, or ICAP, or Server Certification Validation or upstream firewall etc.Īll the endpoints in our organization are Lenovo desktops/PCs which are getting the driver updates from lenovo Vantage (Application in windows). The recommendation would be to perform some troubleshooting by taking a policy trace and and pcap on the proxy to find out the affected destinations and why they are affected. so it is confirmed that the application is not forwarding the traffic to proxy. when i allow the policy on firewall from my src IP to internet, the application works. it seems like the lenovo vantage application is not forwarding the traffic to proxy which we have explicitly configured in browser. The issue is, even I bypassed my src IP using magic script but it did not work. Subject: Lenovo Vantage Not working with Proxy ASG
