**Name of the Vulnerable Software and Affected Versions** D-Link DIR-859 version 1.06B01 **Description** A critical vulnerability has been found in the D-Link DIR-859 router, affecting some unknown functionality of the file /hedwig.cgi of the component HTTP POST Request Handler. The manipulation of the `service` argument with the input ../../../../htdocs/webinc/getcfg/DHCPS6.BRIDGE-1.xml leads to path traversal. This issue allows an attacker to gain information within the device and potentially gain full control over it. The attack may be launched remotely. The estimated number of potentially affected devices worldwide is not specified. However, it is mentioned that threat actors are actively exploiting this vulnerability. **Recommendations** As a temporary workaround, consider disabling the /hedwig.cgi file until a replacement device is installed. Replace the D-Link DIR-859 router with a supported device as soon as possible, since the vendor has confirmed that the product is end-of-life and no patch will be provided.

**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.
