Directory traversal vulnerability in the web interface on the D-Link DWR-116 device with firmware before V1.05b09 allows remote attackers to read arbitrary files via a .. (dot dot) in a "GET /uir/" request.

urlGET /uir/../../../../../../../../../../../../../../../../etc/passwd HTTP/1.1
url/uir//etc/passwd
path/uir/
  • Detect HTTP GET requests to the /uir/ path containing directory traversal sequences (../ repeated) targeting arbitrary filesystem paths such as /etc/passwd.
  • Monitor HTTP responses from D-Link DWR-116 and related routers for passwd-file content (e.g., root:/bin/ash entries) indicating successful traversal exploitation.
  • Unauthenticated exploitation — no credentials required. Flag any unauthenticated requests matching /uir traversal patterns from external/WAN-side sources.
  • ·The original CVE-2017-6190 fix (firmware V1.05b09) was incomplete; the vulnerability persists in newer firmware versions and across additional D-Link router models (DWR-512, DWR-712, DWR-912, DWR-921, DWR-111, DIR-140L, DIR-640L) via the double-slash bypass tracked as CVE-2018-10822.
  • ·Affected firmware versions span multiple device lines through their latest releases at time of disclosure: DWR-116 through 1.06, DWR-512/712/912/921 through 2.02, DWR-111 through 1.01, DIR-140L/640L through 1.02.
  • ·The traversal vulnerability can be chained with CVE-2018-10824 to retrieve administrative credentials from the device.
