Velociraptor priviledge escalation via UpdateConfig artifact

Velociraptor allows collection of VQL queries packaged into Artifacts from endpoints. These artifacts can be used to do anything and usually run with elevated permissions.  To limit access to some dangerous artifact, Velociraptor allows for those to require high permissions like EXECVE to launch. The Admin.Client.UpdateClientConfig is an artifact used to update the client's configuration. This artifact did not enforce an additional required permission, allowing users with COLLECT_CLIENT permissions (normally given by the "Investigator" role) to collect it from endpoints and update the configuration. This can lead to arbitrary command execution and endpoint takeover. To successfully exploit this vulnerability the user must already have access to collect artifacts from the endpoint (i.e. have the COLLECT_CLIENT given typically by the "Investigator' role).

缺省权限不正确

Velociraptor 安全漏洞

Velociraptor是Velocidex开源的一种使用 Velociraptor 查询语言（VQL）查询收集基于主机的状态信息的工具。 Velociraptor存在安全漏洞，该漏洞源于Admin.Client.UpdateClientConfig工件未强制执行额外权限，可能导致任意命令执行和端点接管。
