Vulnerability details

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…

more

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.
