Quick assessment

Affected
Apache Software Foundation Apache CloudStack
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache cloudstack是美国Apache基金会开源的一套云计算管理平台。 Apache CloudStack 4.20.0.0版本至4.20.3.0版本和4.21.0.0版本至4.22.1.0版本存在命令注入漏洞，该漏洞源于命令注入，由于对命令中特殊元素中和不当，经过身份验证的用户通过getDiagnosticsData和runDiagnostics功能可以执行任意命令，可能导致受影响的实例被完全破坏。

Vulnerability Title
Apache CloudStack: Get and Run Diagnostics Command Injection
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in Apache CloudStack's run and get diagnostics functionality for the system VMs and virtual routers. An authenticated user holding the permissions required to invoke either `getDiagnosticsData` or `runDiagnostics` can achieve arbitrary command execution on the system VM and/or Virtual Router instances, with commands running as root (or as the diagnostics-process user, at minimum). This represents a full compromise of the affected instance and, depending on network segmentation, may provide a foothold for lateral movement within the CloudStack-managed infrastructure, including access to guest network traffic handled by the compromised Virtual Router. The getDiagnosticsData and runDiagnostics APIs are restricted to only Admin role accounts by default. This issue affects Apache CloudStack: from 4.20.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
