CVE-2023-48316Network attack vector

Unauthenticated code execution via protocol memory corruption

Published Dec 5, 2023 · Updated Aug 2, 2024

Memory corruption in The Eclipse Foundation Eclipse ThreadX NetX Duo before 6.3.0 allows remote attackers to execute code. SNMP handlers lacked PDU and object-identifier length validation, while SMTP, FTP, and DTLS paths mishandled packet-pointer lifetimes. Unauthenticated access to an enabled affected protocol is sufficient, and successful corruption executes code in the embedded network-stack context.
