CVE-2026-28769 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. A path traversal vulnerability exists in the /IDC_Logging/checkifdone.cgi script in International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver Web management portal version 101. An authenticated attacker can manipulate the `file` parameter to traverse directories and enumerate arbitrary files on the underlying filesystem. EPSS estimates a 0.64% chance of exploitation in the next 30 days.

Description

A path traversal vulnerability exists in the /IDC_Logging/checkifdone.cgi script in International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver Web management portal version 101. An authenticated attacker can manipulate the `file` parameter to traverse directories and enumerate arbitrary files on the underlying filesystem. Due to the insecure perl file path handling function in use, a authenticated actor is able to preform directory traversal, with the backup endpoint confirming a file exists by indicating that a backup operation was successful or when using the path of a non existent file, the returned status is failed.
