Description (CNA)
Podman is a tool for managing OCI containers and pods. Versions 4.8.0 through 5.8.1 contain a command injection vulnerability in the HyperV machine backend in pkg/machine/hyperv/stubber.go, where the VM image path is inserted into a PowerShell double-quoted string without sanitization, allowing $() subexpression injection. Because PowerShell evaluates subexpressions inside double-quoted strings before executing the outer command, an attacker who can control the VM image path through a crafted machine name or image directory can execute arbitrary PowerShell commands with the privileges of the Podman process. On typical Windows installations this means SYSTEM-level code execution, and only Windows is affected as the code is exclusive to the HyperV backend. This issue has been patched in version 5.8.2.

A flaw was found in Podman, a tool for managing containers. This vulnerability, located in the HyperV machine backend, allows for command injection. An attacker who can manipulate the virtual machine (VM) image path can inject and execute arbitrary PowerShell commands. This could lead to unauthorized system-level code execution on Windows installations where Podman is running.
