漏洞描述
中文描述:

Incus是LXC开源的一个系统容器和虚拟机管理器。 Incus 6.20.0及之前版本存在注入漏洞，该漏洞源于用户可通过换行注入在容器配置中添加任意生命周期钩子，可能导致主机上执行任意命令。

英文描述:

Incus is a system container and virtual machine manager. In versions 6.20.0 and below, a user with the ability to launch a container with a custom YAML configuration (e.g a member of the ‘incus’ group) can create an environment variable containing newlines, which can be used to add additional configuration items in the container’s lxc.conf due to newline injection. This can allow adding arbitrary lifecycle hooks, ultimately resulting in arbitrary command execution on the host. Exploiting this issue on IncusOS requires a slight modification of the payload to change to a different writable directory for the validation step (e.g /tmp). This can be confirmed with a second container with /tmp mounted from the host (A privileged action for validation only). A fix is planned for versions 6.0.6 and 6.21.0, but they have not been released at the time of publication.
