VAR-202307-0133

Vulnerability from variot - Updated: 2024-01-07 22:27

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 set_l2tp function with the key variable. 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. (DoS) It may be in a state. Milesight UR32L is a 4G industrial router produced by China Milesight.

There is a buffer overflow vulnerability in the Milesight UR32L set_l2tp function, which can be exploited by an attacker to overflow the buffer and execute arbitrary code on the system, or cause the application to crash
