Threat details

These vulnerabilities could be used to remotely execute arbitrary code on affected devices.

The three vulnerabilities are as follows:

  • CVE-2018-10822 - A vulnerability in the web interface of D-Link routers allows for directory traversal. This vulnerability was believed to have been patched in 2017 (CVE-2017-6190).
  • CVE-2018-10823 - Login credentials, stored as plaintext, can be easily retrieved by an authenticated user. A proof-of-concept exploit for this has already been observed in the wild.
  • CVE-2018-10824 - Admin passwords are stored as plaintext in the temporary folder.
