ctfshow组件漏洞

(Updated: )
ctfshow

web580

首先进来看到一个关键词，搜索破壳RCE漏洞，搜到了一个CVE漏洞，复现一下，bash版本小于等于4.3，会直接执行http头里面的命令，导致漏洞出问题是以(){开头定义的环境变量在命令ENV中解析成函数后，Bash执行并未退出，而是继续解析并执行shell命令，

yaml_parse有漏洞，官方文档

Processing untrusted user input with yaml_parse() is dangerous if the use of unserialize() is enabled for nodes using the !php/object tag. This behavior can be disabled by using the yaml.decode_php ini setting.

也就是说如果!php/object开头的话也就是作为一个标签，就会反序列化

那么我们也进行base64编码，打入即可反弹shell

有NDAY，是写入webshell，可以直接打

CVE-2018-2894，首先弱密码登录admin\admin，WebLogic管理端未授权的两个页面存在任意上传getshell漏洞，可直接获取权限。两个页面分别为/ws_utc/begin.do，/ws_utc/config.do，先访问/ws_utc/config.do把工作目录改成无需权限的CSS目录

1
/u01/oracle/user_projects/domains/base_domain/servers/AdminServer/tmp/_WL_internal/com.oracle.webservices.wls.ws-testclient-app-wls/4mcj4y/war/css

设置-》安全，上传木马shell.jsp，获得时间戳

	out.print("<pre>");
	while((a=in.read(b))!=-1){
		out.println(new String(b));
 	}
	out.print("</pre>");
 }
%>

得到回显时间戳，然后访问即可RCE/ws_utc/css/config/keystore/[时间戳]_[文件名]，这里用ctfshow开半天开不了，直接用vulhub

docker logs 901bc1758d76

admin password  : [rCMtK9ai]

然后后面就是跟着复现就可以了

Apache HTTPD的2.4.0~2.4.29版本中存在一个解析漏洞，在解析PHP时，1.php\x0a将被按照PHP后缀进行解析，上传的时候右键插入一个0a即可

1

然后访问/shell.php%0a

web592

httpd 多后缀解析漏洞，可能之前来说很难，但是现在你给我黑盒我都能做
