DESCRIPTION

Multiple buffer overflow vulnerabilities exist in the vtysh_ubus binary of Milesight UR32L v32.3.0.5 due to the use of an unsafe sprintf pattern. A specially crafted HTTP request can lead to arbitrary code execution. An attacker with high privileges can send HTTP requests to trigger these vulnerabilities.This buffer overflow occurs in the firewall_handler_set function with the ip and mac variables. Milesight Technology of ur32l An out-of-bounds write vulnerability exists in firmware.Information is obtained, information is tampered with, and service operation is interrupted.
