然后sort=abc()的时候404,猜测是Postgresql,于是进一步使用其它函数进行测试,发现sort=pg_ls_dir('/proc')的时候会返回很多结果,sort=pg_ls_dir('/proca')这样就404了,因此可以配合concat和substring进行盲注,例如sort=pg_ls_dir(concat('/proc',substring('a',1,ascii(substring('a'...
Another handy tip while debugging is to add a variable to Watch. By default VSCode shows decimal values but if you want the hex output, append,xto the variable. If you want to see 64 bytes at some pointer address, append*(char(*)[64])to the variable name and combine with appending,x...

How many strings of four decimal digits? a) do not contain the same digit twice? b) end with an even digit? c) have exactly three digits that are 9s? How many three digit odd numbers are possible, if the leftmost digit cannot be zero? How many ...
The cells are formatted as Numeric with 2 decimals and I can't change that either. I am also surprised there seems to be no way to do this. There are many references to empty cells but they really mean one that just looks empty. Frank Livni frank@mstate.com Multi-State Systems, Inc...
This number can be a decimal or hexadecimal (prefix 0x) value. For example, ['ABC']+3 will search for the first instance of string 'ABC' and then select the bytes after ABC (+ 3). Finally, search string expressions (ASCII, UNICODE and hexadecimal) can be followed by an instance and...
