Service interruption via mailpwd heap overflow
Published Aug 28, 2022 · Updated Aug 3, 2024
A heap buffer overflow in formEmailTest in Tenda M3 1.0.0.12(4856) allows remote attackers to interrupt service via mailpwd. The function mishandles the attacker-controlled mailpwd value and writes beyond its allocated heap buffer. The network path requires no authentication or user interaction; the exact failure mode beyond denial of service is undisclosed.
