CVE-2024-58277 identifies a critical vulnerability in the R Radio Network FM Transmitter version 1.07, where sensitive information, specifically the admin user's password, is stored in cleartext and accessible through the system.cgi endpoint. This flaw corresponds to CWE-312, indicating improper protection of sensitive data at rest. An unauthenticated attacker can remotely access this endpoint without any privileges or user interaction, retrieve the admin password, and bypass authentication mechanisms. This unauthorized access allows the attacker to manipulate FM station setup parameters, potentially disrupting broadcast operations or injecting malicious configurations. The vulnerability is network-exploitable, does not require authentication, and affects the confidentiality and integrity of the device's administrative controls. Although no public exploits have been reported yet, the vulnerability's characteristics make it highly exploitable. The CVSS 4.0 base score of 8.7 reflects its critical impact, with network attack vector, low complexity, no privileges or user interaction required, and high confidentiality impact. The lack of available patches or firmware updates at the time of publication increases the urgency for affected organizations to implement compensating controls. This vulnerability highlights the risks of insecure credential storage in embedded broadcasting devices, emphasizing the need for secure development practices and timely vulnerability management.

For European organizations, particularly those involved in broadcasting, media, and telecommunications, this vulnerability poses a significant risk. Exploitation could lead to unauthorized control over FM transmission settings, resulting in potential broadcast disruption, misinformation dissemination, or service outages. The compromise of administrative credentials undermines device integrity and confidentiality, potentially allowing attackers to persistently manipulate broadcast content or disrupt operations. Given the critical role of radio networks in emergency communications and public information dissemination, exploitation could have broader societal impacts. Additionally, organizations may face regulatory and reputational damage if such vulnerabilities lead to service interruptions or data breaches. The vulnerability's remote and unauthenticated nature increases the attack surface, especially if devices are exposed to public or poorly segmented networks. European broadcasters relying on R Radio Network FM Transmitter 1.07 must consider the operational and compliance risks associated with this vulnerability.

1. Immediate isolation of affected FM Transmitter devices from public or untrusted networks to limit exposure. 2. Implement strict network segmentation and firewall rules to restrict access to the system.cgi endpoint only to trusted administrative hosts. 3. Monitor network traffic for unusual access attempts to the management interface and system.cgi endpoint. 4. Engage with R Radio Network vendor support to obtain firmware updates or patches addressing the vulnerability; if unavailable, request guidance on secure configuration. 5. Change all default and potentially compromised administrative passwords once a patch or fix is applied. 6. Employ multi-factor authentication (MFA) on management interfaces where possible to add an additional security layer. 7. Conduct regular security audits and vulnerability assessments on broadcasting infrastructure to detect similar issues. 8. Develop incident response plans specific to broadcast infrastructure compromise scenarios. 9. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting this vulnerability. 10. Educate operational staff about the risks and signs of exploitation to enable rapid detection and response.
