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 6.21.0及之前版本存在路径遍历漏洞,该漏洞源于模板功能中存在目录遍历或符号链接问题,可能导致主机任意文件读写和任意命令执行。

英文描述:

Incus is a system container and virtual machine manager. Versions 6.21.0 and below allow a user with the ability to launch a container with a custom image (e.g a member of the ‘incus’ group) to use directory traversal or symbolic links in the templating functionality to achieve host arbitrary file read, and host arbitrary file write. This ultimately results in arbitrary command execution on the host. When using an image with a metadata.yaml containing templates, both the source and target paths are not checked for symbolic links or directory traversal. This can also be exploited in IncusOS. A fix is planned for versions 6.0.6 and 6.21.0, but they have not been released at the time of publication.
