CVE-2024-32301Network attack vector

Unauthenticated memory corruption via oversized PPW

Published Apr 17, 2024 · Updated Oct 25, 2024

Stack overflow in Tenda AC7 Firmware 15.03.06.44 allows remote attackers to corrupt memory via a crafted PPW parameter. The fromWizardHandle request handler processes attacker-controlled PPW input without preventing a stack overflow; the public record does not disclose the exact copy operation. Network reachability is sufficient, with no authentication or user interaction required, and resulting memory corruption can interrupt routing or alter execution.
