|
|
Sažetak
|
This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
|
|
Preduvjeti

Rješenja
|
['Use a strong source of randomness to generate a session ID.', 'Use adequate length session IDs', 'Do not use information available to the user in order to generate session ID (e.g., time).', 'Ideas for creating random numbers are offered by Eastlake [RFC1750]', 'Encrypt the session ID if you expose it to the user. For instance session ID can be stored in a cookie in encrypted format.']
