CVE-2023-48315Network attack vector

Code execution via FTP and SNTP memory flaws

Published Dec 5, 2023 · Updated Nov 27, 2024

Memory-safety flaws in Eclipse ThreadX NetX Duo before 6.3.0 allow remote attackers to execute code through FTP or SNTP traffic. The advisory identifies out-of-bounds writes and expired-pointer dereferences in FTP- and SNTP-related functions but does not disclose the functions or faulty input operations. No privileges are required, but GitHub’s assessment requires user interaction; successful exploitation can fully compromise the embedded process.
