CVE-2026-89010 (GCVE-0-2026-89010)

Vulnerability from cvelistv5 – Published: 2026-09-11 14:57 – Updated: 2026-09-11 16:16 Unsupported When Assigned

Title

WAVLINK WN535M1/WN535M3 Unauthenticated OS Command Injection via sync_server

Summary

WAVLINK WN535M1 and WN535M3 routers running firmware prior to M35M1_V250922 contain an unauthenticated OS command injection vulnerability that allows remote attackers to execute arbitrary commands as root by sending crafted filenames to the sync_server daemon on TCP port 13136. The daemon interpolates attacker-controlled filename input containing shell metacharacters into a shell command string via sprintf() and passes it to system() without sanitization, enabling root-level command execution on the device.
