CVE-2023-44405

Root code execution via unchecked HNAP1 XML copy

Published May 3, 2024 · Updated Aug 2, 2024

Stack-based buffer overflow in D-Link DAP-1325 1.07b01 allows remote attackers to execute arbitrary code through HNAP1 XML. The get_value_of_key path copies attacker-controlled XML data into a fixed-length stack buffer without validating its length. No authentication or user interaction is required; an adjacent-network request executes code as root and can fully control the extender.
