During communication with a third-party DDNS service, authentication credentials are transmitted over an unencrypted channel. An attacker who can observe or manipulate traffic between an affected device and the DDNS service may obtain sensitive authentication information or interfere with DDNS update operations. Exploitation requires DDNS to be configured, communication with an external DDNS service, and attacker visibility or control of the relevant network path. \n\n\n\n\n\nSuccessful exploitation may result in disclosure of DDNS account credentials, unauthorized access to DDNS management functionality, or modification of DNS records associated with the affected deployment.","published":"2026-08-20T19:16:51.000Z","lastModified":"2026-10-26T10:10:00.000Z","status":"Analyzed","sourceIdentifier":"f23511db-6c3e-4e32-a477-6aa17d310630","cvss":{"version":"4.0","score":6.3,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-319"],"affected":["tp-link/er7212pc firmware","tp-link/er605 firmware","tp-link/er7206 firmware","tp-link/er7406 firmware","tp-link/er707-m2 firmware","tp-link/er7412-m2 firmware","tp-link/er8411 firmware","tp-link/er706w firmware","tp-link/er706w-4g firmware","tp-link/er706wp-4g firmware","tp-link/er703wp-4g-outdoor firmware","tp-link/dr3220v-4g firmware","tp-link/dr3650v firmware","tp-link/dr3650v-4g firmware","tp-link/er603wp-4g-outdoor firmware","tp-link/dr3150 firmware","tp-link/er701-5g-outdoor firmware","tp-link/er605w firmware"],"epss":{"score":0.00345,"percentile":0.27782,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.34%).
