CVE-2022-46562Public exploitNetwork attack vector

Authenticated memory corruption via oversized VPN PSK

Published Dec 23, 2022 · Updated Apr 15, 2025

Stack-based buffer overflow in D-Link DIR-882 1.30B06 and DIR-878 1.30B08 allows remote authenticated users to corrupt memory via a PSK. SetQuickVPNSettings accepts an oversized PSK value and copies it into a fixed-size stack buffer without enforcing the destination boundary. The network management request requires administrative privileges; public records do not establish whether the overwrite only crashes the service or also redirects execution.
