So let me start with the exploit behind the title in this story. D-Link has released a security advisory which is tied to CVE-2024-0769 that goes like this:
** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in D-Link DIR-859 1.06B01. It has been rated as critical. Affected by this issue is some unknown functionality of the file /hedwig.cgi of the component HTTP POST Request Handler. The manipulation of the argument service with the input ../../../../htdocs/webinc/getcfg/DHCPS6.BRIDGE-1.xml leads to path traversal. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-251666 is the identifier assigned to this vulnerability. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed immediately that the product is end-of-life. It should be retired and replaced.
So let’s unpack this. In English, what this is saying is that an attack that can be launched remotely exists that allows attackers to leak session data, achieve privilege escalation, and gain full control via the admin panel. In short, they can take over the router. And presumably use that access to launch secondary attacks. Like theft of data for example via reconfiguring the router to let them have full access to your network. On top of that you’ll note this part:
NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed immediately that the product is end-of-life. It should be retired and replaced.
So this isn’t going to get fixed. Which means that if you have one of these routers, your best course of action is to throw it in the trash (or responsibly recycle it) and get something else. I say that because the word on the street is that threat actors are actively using this exploit to pwn people. Thus you don’t want to be the person on the other end of that.
