Deeper analysis

D-Link Go-RT-AC750 revA_v101b03 contains a command injection vulnerability in the hedwig.cgi component, triggered through the service parameter. The issue is tracked as CVE-2023-48842, carries a CVSS v3.1 score of 9.8, and maps to CWE-77 and CWE-78.

An unauthenticated attacker with network access can supply crafted input to the affected parameter and execute arbitrary operating-system commands. Because the vector requires no credentials or user interaction, successful exploitation yields full control over the device, enabling disclosure, modification, or destruction of data and configuration.

The two reference URLs point to external technical material but contain no vendor advisory text, patch information, or mitigation steps. The associated EPSS score has reached 0.2724 at both its current and peak values.
