CVE-2024-3273
HighCVSS 7.3KEVSummary
A critical command injection vulnerability was found in D-Link DNS-320L, DNS-325, DNS-327L, and DNS-340L up to 20240403. The affected component is the HTTP GET Request Handler in /cgi-bin/nas_sharing.cgi, where manipulation of the system argument leads to command injection. The attack can be launched remotely. The product is end-of-life and no longer supported.
Risk Assessment
A remote attacker could exploit this vulnerability to execute arbitrary commands on the device, potentially leading to full device and network compromise. Since the product is end-of-life, no patches are available.
Recommendation
Retire these devices from service and replace them with newer, supported models. If not possible, restrict access to the devices from external networks.
