**Name of the Vulnerable Software and Affected Versions** Hitron Technologies CODA-5310 (affected versions not specified) **Description** The issue is related to the Telnet function in the Hitron Technologies CODA-5310, which uses a default account and password without prompting users to change them. This allows an unauthenticated remote attacker to exploit the weakness in the authentication procedure, potentially gaining administrator privileges. As a result, the attacker can perform arbitrary system operations or disrupt the service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
