CVE-2023-27105Public exploitNetwork attack vector

System file manipulation via Wi-Fi path traversal

Published Apr 25, 2023 · Updated Feb 3, 2025

Path traversal in Shanling M5S 4.3 and M2X 3.3 Wi-Fi transfer allows remote attackers to read, delete, or modify system files. The module accepts attacker-controlled file paths for transfer operations without confining resolution to its intended directory. Network access to the enabled Wi-Fi file transfer service is sufficient; public material does not identify the affected endpoint or parameter.
