DescriptionCVE.org

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 XSS but further abuse such as XXE may be possible

AnalysisAI

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.
