Summary
In TRENDnet TEW-WLC100P version 2.03b03, the i_dont_care_about_security_and_use_aggressive_mode_psk option is enabled in the strongSwan configuration file. This allows IKE Responders to use IKEv1 Aggressive Mode with Pre-Shared Keys, enabling offline attacks on the openly transmitted PSK hash.
Risk Assessment
An attacker can capture and crack the pre-shared key (PSK) hash during IKE negotiation, leading to VPN authentication compromise and potential unauthorized network access.
Recommendation
Immediately disable the i_dont_care_about_security_and_use_aggressive_mode_psk option in the strongSwan configuration and update the device firmware to the latest version.
