CVE-2024-32287

Service interruption via oversized qos parameter

Published Apr 17, 2024 · Updated Aug 2, 2024

Stack-based buffer overflow in Tenda W30E firmware 1.0.1.25(633) allows remote attackers on an adjacent network to interrupt router service. The fromqossetting handler accepts the qos parameter without enforcing the capacity of its stack buffer, allowing oversized input to overwrite adjacent stack memory. No authentication or user interaction is required; published evidence establishes availability loss but not code execution, data access, or the exact failure mode.
