| Summary | 0000708: Increase complexity of session IDs | ||||
| Description | If someone disables the "Enforce IP addresses for sessions" option, then a brute-force hack-attack (executing within a timeframe of an admin having been active) could steal the admin login. The brute-force would need to last roughly 11-days (if 10 requests per second): (10^7)/(10*3600*24) The default session expiry time is significantly less than this. The following conjunction of events would make a site vulnerable: - A hacker attacking a site - Run by someone who wasn't noticing the ramp-up in (suspicious) hits - Run by someone who'd disabled the "Enforce IP addresses for sessions" option - A persistent attack lasting months (multiples of 11-days, hoping for an overlap between guessing a session ID and that session ID having not yet expired) If we increase the session ID complexity we can reduce the likelihood of a guess significantly. | ||||
