name: Unrestricted MongoDB Access in Azure NSGs
|
|
author: princechaddha
|
|
severity: high
|
|
description: |
|
|
Ensure that Microsoft Azure network security groups (NSGs) do not allow unrestricted inbound access on TCP ports 27017, 27018, and 27019, used by MongoDB, to prevent unauthorized database access.
|
|
impact: |
|
|
Allowing unrestricted access to MongoDB ports can expose databases to risks such as unauthorized data access, data manipulation, or data theft.
|
|
remediation: |
|
|
Modify NSG rules to restrict access on TCP ports 27017, 27018, and 27019. Only allow known IPs and implement database encryption and other security measures.
