Cyclone Matrix TRF: Authentication Bypass by Capture-replay

Published Updated By the CyberSecBulletin desk

CVE-2025-6030 is a critical-severity authentication bypass by capture-replay vulnerability in Cyclone Matrix TRF from Autoeastern, with a CVSS 4.0 base score of 9.4 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. Affected Cyclone Matrix TRF versions: 2024 through 2025. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.22% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Use of fixed learning codes, one code to lock the car and the other code to unlock it, in the Key Fob Transmitter in Cyclone Matrix TRF Smart Keyless Entry System, which allows a replay attack. Research was completed on the 2024 KIA Soluto. Attack confirmed on other KIA Models in Ecuador.

The underlying weakness: Authentication Bypass by Capture-replay

A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).

How developers prevent this class of flaw

  • Utilize some sequence or time stamping functionality along with a checksum which takes this into account in order to ensure that messages can be parsed only once.
  • Since any attacker who can listen to traffic can see sequence numbers, it is necessary to sign messages with some kind of cryptography to ensure that sequence numbers are not simply doctored along with content.
