CVE-2023-25124 (GCVE-0-2023-25124)

Vulnerability from cvelistv5 – Published: 2023-07-06 14:53 – Updated: 2025-11-04 19:15

Summary

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_openvpn_client function with the remote_subnet and the remote_mask variables.

Severity

7.2 (High)
