CVE-2023-32140

Root code execution via sys_Token heap overflow

Published May 3, 2024 · Updated Feb 5, 2025

Heap-based buffer overflow in D-Link DAP-1360 6.14b01 and earlier allows remote attackers to execute code as root from the adjacent network. The /cgi-bin/webproc handler copies an overlong var:sys_Token value into a fixed-length heap buffer without validating its length. Exploitation requires adjacent-network access but neither authentication nor user interaction.
