中文标题:
Google Cloud Platform guest-oslogin 安全漏洞
英文标题:
Priviged Escalation in Google Cloud Platform's Guest-OSLogin
漏洞描述
中文描述:
Google Cloud Platform是美国谷歌(Google)公司的一款能够提供云计算、数据存储、数据分析及机器学习等服务的云计算平台。 Google Cloud Platform中的guest-oslogin 20190304版本至20200507之前版本中存在安全漏洞。攻击者可利用该漏洞将权限提升至root。
英文描述:
A vulnerability in Google Cloud Platform's guest-oslogin versions between 20190304 and 20200507 allows a user that is only granted the role "roles/compute.osLogin" to escalate privileges to root. Using their membership to the "adm" group, users with this role are able to read the DHCP XID from the systemd journal. Using the DHCP XID, it is then possible to set the IP address and hostname of the instance to any value, which is then stored in /etc/hosts. An attacker can then point metadata.google.internal to an arbitrary IP address and impersonate the GCE metadata server which make it is possible to instruct the OS Login PAM module to grant administrative privileges. All images created after 2020-May-07 (20200507) are fixed, and if you cannot update, we recommend you edit /etc/group/security.conf and remove the "adm" user from the OS Login entry.
