Overview
CVE-2024-58277 describes a critical vulnerability affecting R Radio Network FM Transmitter version 1.07. This vulnerability allows unauthenticated attackers to retrieve the administrator’s password through the system.cgi endpoint. Successful exploitation of this vulnerability grants unauthorized access to the FM station’s configuration settings and allows for complete authentication bypass.
Technical Details
The vulnerability stems from insufficient access control on the system.cgi endpoint. The application fails to properly authenticate users before allowing access to sensitive system information, including the administrator’s password. An attacker can simply request the system.cgi endpoint to retrieve this sensitive information without providing any credentials.
CVSS Analysis
Currently, the CVSS score and severity are listed as N/A. However, given the nature of the vulnerability – unauthenticated access to the admin password – a manual assessment would likely place the severity as Critical with a CVSS score potentially in the range of 9.0 – 10.0. This is based on the potential for complete system compromise. Awaiting formal CVSS assignment is highly recommended.
Possible Impact
The impact of this vulnerability is severe:
- Full System Compromise: Attackers can gain complete control over the FM transmitter.
- Authentication Bypass: Attackers bypass the authentication mechanism.
- Unauthorized Configuration Changes: Attackers can modify FM station settings, potentially disrupting broadcasts or injecting malicious content.
- Denial of Service: Attackers could potentially disable the FM transmitter, causing a complete outage.
- Data Exposure: Other sensitive information beyond the administrator password might be accessible via the same or related vulnerabilities.
Mitigation or Patch Steps
Unfortunately, there is no officially released patch for R Radio Network FM Transmitter 1.07 at the time of this writing. The following mitigation steps are recommended:
- Immediate Shutdown: If possible, immediately shut down the FM transmitter to prevent exploitation.
- Network Segmentation: Isolate the FM transmitter on a segmented network with restricted access.
- Firewall Restrictions: Implement strict firewall rules to limit access to the FM transmitter’s web interface to only trusted IP addresses.
- Monitor Network Traffic: Continuously monitor network traffic for suspicious activity targeting the
system.cgiendpoint. - Contact the Vendor: Contact the vendor, R Radio Network, to inquire about a security patch or upgrade. Emphasize the severity of this vulnerability.
- Consider Alternative Solutions: If a patch is not forthcoming, consider migrating to a more secure FM transmitter solution.
