Service interruption via unchecked list parameter copy
Published Jul 10, 2024 · Updated Aug 2, 2024
Stack-based buffer overflow in Tenda AX1806 Firmware 1.0.0.1 allows remote attackers on an adjacent network to interrupt router service via POST. SetIpMacBind passes the unbounded list POST parameter through fromSetIpMacBind to strcpy without checking its length, overflowing a stack buffer. The attack requires adjacent-network reachability but no authentication or user interaction, with no published ability to read or alter data.
