AnalysisAIv1 – Mar 12, 2026

XML injection in the IDC SFX2100 satellite receiver web interface allows authenticated attackers to inject arbitrary XML elements and execute reflected cross-site scripting attacks through unsanitized input in the checkifdone.cgi script. Public exploit code exists for this vulnerability, and potential for more severe attacks such as XXE exploitation has not been ruled out. No patch is currently available for affected firmware versions.

Affects Sfx2100 Firmware. Improper neutralization of special elements in the /IDC_Logging/checkifdone.cgi script in International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver Web management Interface version 101 allows for XML Injection. The application reflects un-sanitized user input from the file parameter directly into a CDATA block, allowing an authenticated attacker to break out of the tags and inject arbitrary XML elements. An actor is confirmed to be able to turn this into an reflected

Executive ViewAI

Why It Matters

A high-severity XML injection vulnerability affects IDC SFX Series SuperFlex Satellite Receiver web interfaces, allowing attackers to manipulate application logic and potentially access sensitive data. Organizations operating these devices face immediate risk as public exploits are available and no vendor patch currently exists, requiring urgent interim mitigation measures.

Business Impact: High

Compensating Controls

Restrict network access to /IDC_Logging/checkifdone.cgi via firewall rules or network segmentation; deploy Web Application Firewall (WAF) with XML injection detection signatures; disable the checkifdone.cgi script if operationally feasible; implement strict input validation and output encoding on the application layer; monitor for exploitation attempts through enhanced logging; consider isolating affected devices to air-gapped networks pending patch availability.
