Description OSIDB Bzimport 2026-11-05 22:26:36 UTC
Certain Yealink terminal devices before 2026-04-21 contain an improper access control vulnerability in the Wi-Fi 802.1X PEAP network configuration function. This flaw exposes deployed 802.1X network access authentication credentials to unauthorized users. The latest Yealink firmware has addressed this vulnerability by restricting 802.1X configuration modification privileges to administrator accounts only by default.
