Description

Using Aggressive Mode with pre-shared keys exposes inherent vulnerabilities with Aggressive Mode's Phase 1 clear-text exchange. These vulnerabilities are exaggerated via short key lengths or insecure encryption algorithms. An attacker can gather all the necessary information in order to perform an off-line dictionary attack and compromise the confidentiality and integrity of the data.
