Estado: ModificadaAlta (8.8)—

An exploitable format string vulnerability exists in the iw_console conio_writestr functionality of the Moxa AWK-3131A firmware version 1.13. A specially crafted time server entry can cause an overflow of the time server buffer, resulting in remote code execution. An attacker can send commands while authenticated as a low privilege user to trigger this vulnerability.
