CVE-2022-44808
A command injection vulnerability has been found on D-Link DIR-823G devices with firmware version 1.02B03 that allows an attacker to execute arbitrary operating system commands through well-designed /HNAP1 requests.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.87%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A command injection vulnerability has been found on D-Link DIR-823G devices with firmware version 1.02B03 that allows an attacker to execute arbitrary operating system commands through well-designed /HNAP1 requests. Before the HNAP API function can process the request, the system function executes an untrusted command that triggers the vulnerability.
