A vulnerability was determined in TRENDnet TEW-WLC100 2.05b02. This affects an unknown function of the file /etc/racoon.conf of the component IKE Phase 1 Aggressive Mode. This manipulation of the argument exchange_mode causes missing encryption of sensitive data. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is reported as difficult. The vendor was contacted early about this disclosure.
AI Analysis
Technical Summary
This vulnerability affects TRENDnet TEW-WLC100 version 2.05b02 and is related to the IKE Phase 1 Aggressive Mode configuration in the file /etc/racoon.conf. Manipulating the exchange_mode argument causes sensitive data to be transmitted without encryption. The attack can be initiated remotely, but the complexity is high and exploitability is difficult. The vendor was notified early, but no remediation level or patch information is provided in the available data.
Potential Impact
Sensitive data may be transmitted unencrypted due to the vulnerability, potentially exposing it to interception by remote attackers. However, the attack complexity is high and exploitability is difficult, which reduces the likelihood of successful exploitation. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or workaround is documented, monitoring vendor communications for updates is recommended.
