Description

External control of file name or path in Azure Stack Edge allows an unauthorized attacker to execute code over a network.

FAQ

How could an attacker exploit this vulnerability? An attacker could send a specially crafted file upload request that includes a manipulated file name or path. Because the application does not properly restrict or validate this input, the attacker could cause the file to be written outside the intended folder, potentially overwriting or creating files in other locations on the system.
