CVE-2024-44341 is a remote command execution (RCE) vulnerability identified in the D-Link DIR-846W A1 router firmware version FW100A43. The vulnerability arises from improper input validation or sanitization of the lan(0)_dhcps_staticlist parameter, which is processed by the router’s web management interface. An attacker can send a specially crafted POST request targeting this parameter to inject and execute arbitrary system commands remotely. The vulnerability requires the attacker to have low privileges (PR:L) and network access to the device, but does not require user interaction (UI:N). The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). The weakness corresponds to CWE-78 (Improper Neutralization of Special Elements used in an OS Command). No patches or official fixes have been published at the time of disclosure, and no known exploits have been observed in the wild. This vulnerability could allow attackers to fully compromise the router, potentially leading to network traffic interception, device manipulation, or pivoting to other internal systems.

The impact of CVE-2024-44341 is significant for organizations and individuals using the affected D-Link DIR-846W A1 routers. Successful exploitation grants attackers the ability to execute arbitrary commands remotely, compromising the router’s confidentiality, integrity, and availability. This could lead to unauthorized access to network traffic, modification of router configurations, installation of persistent malware, or denial of service. For enterprises relying on these devices in branch offices or small networks, this vulnerability could serve as a foothold for lateral movement and further network compromise. The lack of patches increases the window of exposure, and the ease of exploitation via a simple POST request heightens the risk. The vulnerability is particularly dangerous in environments where the router’s management interface is accessible from untrusted or semi-trusted networks.

1. Immediately restrict access to the router’s management interface to trusted internal networks only, using firewall rules or VLAN segmentation. 2. Disable remote management features if not required to reduce exposure. 3. Monitor network traffic for unusual POST requests targeting the lan(0)_dhcps_staticlist parameter or other suspicious activity on the router’s web interface. 4. Use network intrusion detection/prevention systems (IDS/IPS) to detect exploitation attempts based on known attack patterns. 5. Regularly audit router configurations and logs for signs of compromise. 6. Contact D-Link support for any available patches or firmware updates and apply them promptly once released. 7. Consider replacing affected devices with models that have confirmed security updates if patching is delayed. 8. Educate network administrators about the vulnerability and enforce strong network segmentation to limit attacker access to critical devices.
