CVE-2024-9692 VIMESA CVE debrief

CVE-2024-9692 is a medium-severity denial-of-service vulnerability affecting the VIMESA VHF/FM Transmitter Blue Plus (version 9.7.1). Published on October 24, 2024, this vulnerability allows unauthenticated remote attackers to restart transmitter operations by sending an unauthorized HTTP GET request to the unprotected 'doreboot' endpoint. The CVSS 3.1 score of 5.3 reflects network accessibility, low attack complexity, no required privileges or user interaction, and low availability impact with no confidentiality or integrity impact. This vulnerability poses particular concern for broadcast infrastructure operators, as successful exploitation could disrupt FM radio transmission services without requiring authentication. CISA has noted that VIMESA has not responded to coordination requests to develop mitigations, leaving users dependent on direct vendor engagement for remediation guidance.

Who should care

Broadcast engineering teams operating VIMESA FM transmission equipment, critical infrastructure security teams managing radio broadcast systems, network security architects designing segmentation for media and entertainment operational technology environments, and regulatory compliance officers responsible for FCC-licensed broadcast facility security

Technical summary

The VIMESA VHF/FM Transmitter Blue Plus exposes an unprotected HTTP endpoint at 'doreboot' that processes GET requests without authentication. Remote attackers can trigger this endpoint to initiate a system reboot, causing denial of service by interrupting FM broadcast transmission operations. The vulnerability is network-exploitable with no prerequisites, making it accessible to any attacker with network reachability to the device management interface. No confidentiality or integrity impacts are associated with this vulnerability; the sole impact is availability degradation through forced restart.

Defensive priority

medium

Recommended defensive actions

  • Contact VIMESA directly for security updates or mitigation guidance, as the vendor has not coordinated with CISA on fixes
  • Restrict network access to the transmitter's management interface to authorized administrative hosts only
  • Implement network segmentation to isolate broadcast transmission equipment from general enterprise networks
  • Monitor for unauthorized HTTP GET requests to endpoints containing 'doreboot' or similar system control functions
  • Apply defense-in-depth strategies for industrial control systems per CISA guidance
  • Review and strengthen authentication requirements for all administrative endpoints on broadcast infrastructure equipment
