Moderate vulnerability in argentinean ARNET isp webmail. well, there is some kind of weakened authentication on the webmail of Arnet (webmail.arnet.com.ar) to access any account all you need is to guess the first 8 characters of the password, even if the password is 9,10,11,12,14 or more characters long. This password is the same than ADSL access acount. for example: For this account johndoe () arnet com ar password:a1a2a3a4a5a6a7a8a9a0 you only need (first 8 character) johndoe () arnet com ar password:a1a2a3a4 ADSL account in this case is Name: johndoe@arnet Password:a1a2a3a4a5a6a7a8a9a0 there are no anti bruteforce mecanism so you can guess almost any account within a couple of hours. _______________________________________________ Full-Disclosure - We believe in it.
