CVE-2023-24169Network attack vector

Unauthenticated memory corruption via malformed web request

Published Jan 26, 2023 · Updated Mar 28, 2025

Buffer overflow in Tenda AC18 firmware 15.03.05.19 allows remote attackers to corrupt memory through a crafted request to its web interface. The /goform/FUN_0007343c handler accepts attacker-controlled request data, but public records do not identify the parameter, copy operation, or buffer boundary. Network access is sufficient and no authentication or user interaction is required; no consequence more specific than memory corruption is published.
