VPN Pre-Shared Master Secret Leakage
When a VPN is configured to use a pre-shared master secret and a client attempts to negotiate keys in aggressive mode, a hash of the secret is transmitted across the network in clear-text. This may result in the hash being leaked to eavesdroppers or malicious clients. An offline brute-force attack on this hash may then be performed to obtain the clear-text secret.
Mitigation:
Ensure that the pre-shared master secret is not transmitted in clear-text over the network.
