Unauthenticated denial of service via unchecked MAC length
Published May 6, 2022 · Updated Aug 3, 2024
Heap overflow in Tenda AX1806 1.0.0.1 allows remote attackers to interrupt service through a crafted mac parameter sent to GetParentControlInfo. The /bin/tdhttpd handler copies the POST mac value directly into heap memory without checking its length. No authentication or user interaction is required; published evidence demonstrates service interruption but does not state whether the router crashes or hangs.
