Hi,
i have been trying to modify waraxes exploit in order to get data from another tables, specifically from ibf_admin_login_logs but i always get an error saying its the wrong prefix. Basically what i did is to copy the modification model from a exploit that was modified to get the username and basically its just question of changing the name of the table "members" to "ibf_admin_login_logs" in thisc ase but i cant get it to work. Can smebody please help me with this?
Thank you! |

i got it to work finally. Now i can fetch the admin logins details which includes the password although partially hidden you have at least how many characters has and which character is the last one. However, the only problem is that it cant tell apart symbols so instead of displaying ",% or whatever symbol it shows an A or a 0 which makes it a little confusing to read. If somebody can tell me how can i modify the code so it reads every character properly i would really appreciate it.
Thanks. |

Wow...I didn't even know it stored passwords like that.
I'll get on that for you and come up with a solution. |

This will work, but you need to scroll down to $i = 370 and manually change the 370 to whatever location you think the mask starts at.
I am working on automating that at the moment, till then, you might want to try increments of 100 till you start getting blanks, then retrace in decrements of 10 till you're back in the field, then just wait for it to reveal teh pass.
Good luck.

Ｈｉ，
sorry, i hadnt seen your reply until now. Actually i had managed to figure it the code myself and now it works splendidly. Its a shame only the last character of the password is shown as it is and the rest is masked but at leasts it lets you know also how many characters does the password have. Thank you anyway. |
