CVE-2022-45997Network attack vector

Authenticated memory corruption via undisclosed network input

Published Dec 12, 2022 · Updated Apr 22, 2025

Buffer overflow in Tenda W20E firmware 16.01.0.6(3392) allows remote authenticated users to corrupt memory through network requests. The published record and deleted proof-of-concept do not identify the affected handler, input field, buffer operation, or request path. Administrative privileges are required, while public evidence does not establish whether exploitation causes only a crash or permits broader device compromise.
