Name of the Vulnerable Software and Affected Versions
D-Link DIR-846 version FW100A53DBR
Description
A critical vulnerability was found in the D-Link DIR-846 router, affecting an unknown part of the file /HNAP1/ of the component QoS POST Handler. The manipulation of the
smartqos express devices and smartqos normal devices arguments leads to deserialization, allowing an attacker to initiate the attack remotely by sending a specially crafted POST request. The exploit has been disclosed to the public and may be used.Recommendations
As a temporary workaround, consider disabling the QoS POST Handler until a patch is available. Restrict access to the /HNAP1/ file to minimize the risk of exploitation. Avoid using the
smartqos express devices and smartqos normal devices arguments in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
OS Command Injection
Deserialization of Untrusted Data
