CVE-2023-30602Network attack vector

Credential disclosure via plaintext Telnet authentication

Published Jun 2, 2023 · Updated Jan 8, 2025

Cleartext transmission in Hitron CODA-5310 7.2.4.7.1b3 allows remote attackers to read user and administrator credentials over Telnet. The Telnet function sends authentication data without transport encryption, exposing account names and passwords to network capture. No account is needed to collect the exposed credentials, but interception requires access to the network path carrying a Telnet session.
