Okay, here is a good question after read the updated version of HD Moore Blog post [1]: (btw, that is the same question we are talking in twitter) - Based on the blog post "Results of Investigation into Holyday ISS Claim" (MSRC) [2], there is no vulnerability related to this case, right? BUT... If a user has a weak password, a guessable password, you can GUESS the user's password and get the user's access... Getting all the privileges he/she has. Okay, I know that there are a lot of best practices floating around, describing many, many ways to enforce the users to create a strong password instead... But according to my experience in pen-tests, the easiest way to get a system access is guessing users' passwords. RIGHT? In a dynamic WWW, things change and "'write' and 'execute' privileges on the same directory" (QUOTED) [2] is not a "IMPOSSIBLE AND UNBELIEVABLE" thing. "If the weather is good, the waves are good... Let's surfing!" So I think they should change the term "not a vulnerability" to "vulnerabilistic feature"... I know that this word does not exist, anyway. =) PS: Don't send me any flame if you didn't check the "vulnerability" [3] definition.
