CVE-2026-19891: Missing Encryption of Sensitive Data in TRENDnet TEW-WLC100
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
CVE-2026-19891 is a vulnerability in TRENDnet TEW-WLC100 version 2.05b02 related to the IKE Phase 1 Aggressive Mode configuration in the /etc/racoon.conf file. Manipulating the exchange_mode argument causes sensitive data to be transmitted without encryption. The vulnerability is remotely exploitable but requires high attack complexity and no privileges or user interaction. The CVSS v3.1 base score is 3.7, indicating a moderate severity level. There is no information about a patch or remediation from the vendor.
Potential Impact
The vulnerability leads to missing encryption of sensitive data during the IKE Phase 1 Aggressive Mode exchange, potentially exposing sensitive information to remote attackers. However, the attack complexity is high, and no known exploits are reported in the wild, limiting immediate risk.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting remote access to the affected device and monitor for unusual activity related to IKE exchanges.
