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 src and dmz variables.

## The many vulnerabilities Talos discovered in SOHO and industrial wireless routers post-VPNFilter
Since the discovery of the widespread VPNFilter malware in 2018 , Cisco Talos researchers have been researching vulnerabilities in small and home office (SOHO) and industrial routers.
During that research, Talos has worked with vendors to report and mitigate these vulnerabilities, totaling 141 advisories covering 289 CVEs across multiple routers.
Talos is highlighting some of the major issues our researchers discovered over the past several years, including vulnerabilities that an attacker could mostly directly access or those an adversary could chain together to gain elevated access to the devices.
There are several Snort rules that can detect possible exploitation of the vulnerabilitie

## Taking over Milesight UR32L routers behind a VPN: 22 vulnerabilities and a full chain
Cisco Talos discovered 17 vulnerabilities (63 CVEs) in the Milesight UR32L router and five vulnerabilities (six CVEs) in the Milesight MilesightVPN remote access solution software.
An attacker could exploit the vulnerabilities discovered to completely compromise the UR32L and MilesightVPN.
This post presents an attack scenario in which the UR32L is only reachable through the MilesightVPN remote access solution. The blog explains how an attacker could exploit the MilesightVPN and then fully compromise the UR32L.
Update: Milesight informed us on Aug. 4, 2023 that they have released firmware version 32.3.0.7 to address these issues. Talos has confirmed that the issues no longer reproduce on this firmw
