Frequently asked questions

What is TVT NVMS-1000 and what is it used for?

TVT NVMS-1000 is network video management software used to manage security cameras and recording devices. It is commonly deployed for remote monitoring and administrative access to these systems.

What type of vulnerability is CVE-2019-20085?

CVE-2019-20085 is a directory traversal vulnerability (CWE-22). This weakness allows an attacker to access files and directories on the server that they normally would not have access to by manipulating input, such as URLs, to reference files outside the intended directory.

How can an attacker exploit this vulnerability?

An attacker can exploit this vulnerability by sending a specially crafted GET request to the affected TVT NVMS-1000 device. This crafted request manipulates the path to access sensitive files and directories outside of the intended web root.

Who should be concerned about this vulnerability?

Organizations using TVT NVMS-1000 devices should be concerned. Halo classifies this CVE as external, meaning it's likely to be internet-facing, making it a potential target for remote attackers.

What is the first step to address this threat?

The immediate first step is to identify all TVT NVMS-1000 assets within your environment. It is also recommended to limit network access to these devices and apply any available vendor fixes once identified.
