192.168.184.214/shell.php?code=file://../../../..//etc/passwd 有什么问题
时间: 2023-11-19 09:04:17 浏览: 230
这是一个典型的文件包含漏洞,攻击者可以通过构造特定的请求,让服务器将敏感文件包含进来,从而获取敏感信息。在这个例子中,攻击者试图通过访问`192.168.184.214/shell.php?code=file://../../../..//etc/passwd`来获取服务器上的`/etc/passwd`文件,如果服务器存在文件包含漏洞,攻击者就可以成功获取该文件的内容。这种漏洞通常是由于程序没有对用户输入进行充分的验证和过滤导致的。为了防止这种漏洞的出现,开发人员应该对用户输入进行严格的过滤和验证,避免将用户输入作为文件路径或命令执行。同时,服务器也应该及时更新补丁,避免已知的漏洞被攻击者利用。

根据您提供的命令输出,您在执行`kubeadm init`命令时遇到了一些错误。让我们逐个来解决这些问题:
1. [WARNING Hostname]: hostname "his" could not be reached
[WARNING Hostname]: hostname "his": lookup his on 192.168.8.254:53: no such host
这个警告意味着您的主机名无法解析。您可以通过编辑`/etc/hosts`文件来解决此问题,并将`his`主机名映射到正确的IP地址。示例如下:
```shell
sudo nano /etc/hosts
```
在文件中添加以下行:
```
192.168.8.109 his
```
保存并关闭文件。
2. [ERROR CRI]: container runtime is not running: output: E0714 18:14:51.757340 11481 remote_runtime.go:616] "Status from runtime service failed" err="rpc error: code = Unavailable desc = connection error: desc = \"transport: Error while dialing dial unix /var/run/containerd/containerd.sock: connect: no such file or directory\""
此错误指示容器运行时未运行。这可能是由于您的容器运行时(例如containerd)未正确安装或配置导致的。请确保您已按照正确的步骤安装和配置了容器运行时。您可以尝试重新安装或重新配置容器运行时来解决此问题。
3. [ERROR FileContent--proc-sys-net-bridge-bridge-nf-call-iptables]: /proc/sys/net/bridge/bridge-nf-call-iptables contents are not set to 1
这个错误表示`/proc/sys/net/bridge/bridge-nf-call-iptables`文件的内容不是1。您可以通过运行以下命令来解决此问题:
```shell
echo 1 | sudo tee /proc/sys/net/bridge/bridge-nf-call-iptables
```
4. [ERROR KubeletVersion]: the kubelet version is higher than the control plane version. This is not a supported version skew and may lead to a malfunctional cluster. Kubelet version: "1.27.3" Control plane version: "1.25.0"
这个错误表示您的kubelet版本高于控制平面版本。这不是受支持的版本差异,并且可能导致集群功能异常。为了解决此问题,您需要确保kubelet和控制平面使用相同的Kubernetes版本。您可以尝试升级或降级kubelet版本,以与控制平面版本匹配。
请根据上述解决方案逐个解决问题,并尝试重新执行`kubeadm init`命令。如果问题仍然存在,请提供更多详细信息,以便我们能够更好地帮助您解决问题。
