CVE-2025-44647: n/a
In TRENDnet TEW-WLC100P 2.03b03, the i_dont_care_about_security_and_use_aggressive_mode_psk option is enabled in the strongSwan configuration file, so that IKE Responders are allowed to use IKEv1 Aggressive Mode with Pre-Shared Keys to conduct offline attacks on the openly transmitted hash of the PSK.
AI Analysis
Technical Summary
The TRENDnet TEW-WLC100P device running version 2.03b03 has a security weakness due to the enabled 'i_dont_care_about_security_and_use_aggressive_mode_psk' option in its strongSwan VPN configuration. This setting allows IKE Responders to use IKEv1 Aggressive Mode with Pre-Shared Keys, which exposes the hash of the PSK over the network. Attackers can perform offline brute-force or dictionary attacks against this hash to recover the PSK, undermining VPN security. This vulnerability affects confidentiality, integrity, and availability of the VPN communications.
Potential Impact
An attacker can capture the hash of the pre-shared key transmitted during the IKEv1 Aggressive Mode handshake and perform offline attacks to recover the PSK. Successful exploitation can lead to unauthorized access to VPN communications, compromising confidentiality and integrity, and potentially disrupting availability.
Mitigation Recommendations
No official patch or vendor advisory is currently provided for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, it is recommended to disable IKEv1 Aggressive Mode with Pre-Shared Keys in the strongSwan configuration or avoid using vulnerable versions. Consider using more secure authentication methods such as certificates or IKEv2 where possible.
