Exploitation of various vulnerabilities and some search parameters
When it comes to vulnerabilities, the first thing you should mention is a bug that uploads the web.
"Hole net" loophole opened up the prologue of the file of loophole, other system on
The leaks are coming!

1, this loophole is not too serious, using the network forum people know, post directly to write JavaScript will be filtered split, write HTTP will automatically add links,
Today I see some people in the group asked about the hexadecimal coding problem, so use JS to write a small program to convert, remember: This is just coding, not encryption!
String hexadecimal encoding:
Copy Code code as follows:
Str= "http://www.qq.com";
Len=str.length;
Arr=[];
for (Var i=0;iArr.push (Str.charcodeat (i). toString (16));
}
Console.log ("\\x" +arr.join ("\\x"));
Hex-encoded SPIN string:
Copy Code code as follows:
Str= "\x68\x74\x74\
