CVE-2002-1623 describes a design flaw in the Internet Key Exchange (IKE) protocol's Aggressive Mode, specifically affecting Check Point VPN-1/FireWall-1. This vulnerability allows remote attackers to discover valid usernames because initiator and responder identities are not encrypted during negotiation, even before password authentication. With a CVSS score of 5.0, this low-complexity attack can lead to information disclosure (username enumeration) without requiring authentication. Despite its age and a high FAUCET Risk Score of 97/100, there is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
