Re: [sqlmap-users] New feature

[Carlos G. V. <car...@gm...>]

For the last case, i mean to encode all the injection using %.

For example:

http://somehost/script.asp?id=SELECT%20FIELD%20FROM%20TABLE

to

http://somehost/script.asp?id=%53%45%4c%45%43%54%20%46%49%45%4c%44%20%46%52%4f%4d%20%54%41%42%4c%45

This could be combined with the script that double encodes, since you
can stack tamper scripts.
By the way, a nice online tool to encode/decode can be found at:
