We now need to determine the correct offset in order get code execution. It seems that host is not responding anymore and this is G00D )įinding our Exploit using a debugger | Metasploit Unleashed Controlling Execution Flow 0002 LIST () /"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABBBBCCCC" "PWNED" Sending fuzzed data, buffer length = 1012 Authenticating as test with password test. We can go ahead and rebuild our buffer (fuzzed = “A”*1004 + “B”*4 + “C”*4) to confirm that the execution flow is redirectable through a JMP ESP address as a ret.
At the end of that effort we found that we could overwrite EIP, making ESP the only register pointing to a memory location under our control (4 bytes after our return address). Previously we looked at Fuzzing an IMAP server in the Simple IMAP Fuzzer section.
