CVE-2026-28774 is an OS Command Injection vulnerability classified under CWE-78 affecting the International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver Web Management Interface, specifically version 101. The vulnerability resides in the web-based Traceroute diagnostic utility, where the 'flags' parameter is improperly sanitized, allowing an authenticated attacker to inject shell metacharacters like the pipe '|' operator. This injection leads to arbitrary command execution on the underlying operating system with root privileges, granting full control over the device. The vulnerability does not require user interaction but does require authentication, which could be obtained through credential compromise or insider threat. The CVSS 4.0 score of 9.3 reflects the vulnerability's critical nature, with network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. The affected product is specialized satellite receiver management software used in broadcast and satellite data distribution environments. No patches or exploit code are currently publicly available, but the severity and root-level access potential make this a high-priority issue. The vulnerability could allow attackers to disrupt satellite data services, exfiltrate sensitive information, or pivot into broader network infrastructure.

The impact of CVE-2026-28774 is severe for organizations using IDC SFX Series SuperFlex SatelliteReceiver devices. Successful exploitation grants root-level command execution, enabling attackers to fully compromise the device, disrupt satellite data distribution, manipulate broadcast content, or use the device as a foothold for lateral movement within critical infrastructure networks. This could lead to significant operational outages, data breaches, and loss of service integrity in satellite communications. Given the specialized nature of the product, affected organizations are likely to be in broadcasting, government, defense, and satellite communication sectors, where availability and data integrity are paramount. The compromise of such devices could also have cascading effects on dependent systems and services, potentially impacting national security and commercial satellite operations.

1. Immediately restrict access to the web management interface to trusted networks and users only, using network segmentation and firewall rules. 2. Enforce strong authentication mechanisms and monitor for suspicious login attempts to prevent unauthorized access. 3. Implement strict input validation and sanitization on all user-supplied parameters, especially those passed to OS commands, to prevent injection attacks. 4. Disable or restrict the use of the Traceroute diagnostic utility if not essential. 5. Monitor device logs for unusual command execution patterns or unexpected system behavior. 6. Coordinate with IDC for timely patch releases and apply security updates as soon as they become available. 7. Conduct regular security audits and penetration testing focused on management interfaces of satellite receiver devices. 8. Employ intrusion detection/prevention systems (IDS/IPS) to detect exploitation attempts targeting this vulnerability.
