CVE-2024-33180Public exploitNetwork attack vector

Unauthenticated memory corruption via oversized deviceId

Published Jul 16, 2024 · Updated Aug 2, 2024

Stack-based buffer overflow in Tenda AC18 15.03.3.10_EN allows remote attackers to corrupt memory through a crafted deviceId request. The /goform/saveParentControlInfo handler accepts deviceId input without enforcing the stack buffer's size before storing it, causing attacker-controlled data to overrun stack memory. No authentication or user interaction is required; the public proof of concept establishes memory corruption but does not demonstrate arbitrary code execution.
