Summary

CVE-2026-28774 is a critical-severity OS Command Injection (CWE-78) vulnerability in Datacast Sfx2100 Firmware. Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 17% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2026-28774 is an OS Command Injection vulnerability (CWE-78) in the web-based Traceroute diagnostic utility of the International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver Web Management Interface version 101. Published on 2026-03-04, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its network accessibility, low attack complexity, and potential for significant impacts on confidentiality, integrity, and availability.

An authenticated attacker with low privileges (PR:L) can exploit the vulnerability by injecting arbitrary shell metacharacters, such as the pipe `|` operator, into the flags parameter of the Traceroute utility. Successful exploitation enables the execution of arbitrary operating system commands with root privileges, allowing full control over the affected device.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
