CVE-2023-30367 : Vulnerability Insights and Analysis

A critical vulnerability in mRemoteNG versions <= v1.76.20 and <= 1.77.3-dev allows attackers to access plain text configuration files through a memory dump, compromising user credentials.

Understanding CVE-2023-30367

mRemoteNG is a free software used for managing multi-protocol connection configurations to remotely connect to systems. The vulnerability lies in how the application loads configuration files in plain text into memory at start-up, exposing sensitive data.

What is CVE-2023-30367?

CVE-2023-30367 exposes mRemoteNG users to credential compromise by allowing attackers to extract plain text configuration files from memory without the need for custom password encryption keys.

The Impact of CVE-2023-30367

The vulnerability poses a significant risk as it bypasses the encryption settings, enabling threat actors to extract decrypted connection configurations and compromise user credentials.

Technical Details of CVE-2023-30367

The vulnerability in mRemoteNG allows attackers to access sensitive information by dumping plain text configurations from memory, even without established connections.
