Two vulnerabilities have been identified in RapidFire Tools Network Detective, a system assessment and reporting tool developed by Kaseya (RapidFire Tools). These issues significantly compromise the confidentiality and integrity of credentials gathered and processed during routine network scans, exposing sensitive data to both local attackers and potentially malicious insiders.
Vulnerability 1: Passwords in Cleartext
During its normal operation, Network Detective saves usernames and passwords in plain, readable text across several temporary files. These files are stored locally on the device and are not protected or hidden. In many cases, the credentials collected include privileged or administrative accounts, such as those used for VMware.
An attacker who gains access to the machine running the scan—whether physically, remotely, or through malware—can easily retrieve these passwords without needing to decrypt anything. This presents a serious risk to client infrastructure, especially when those credentials are reused or provide broad system access.
Vulnerability 2: Reversible Encryption
RapidFire Tools Network Detective uses a flawed method to encrypt passwords and other sensitive data during network scans. The encryption process is based on static, built-in values, which means it produces the same result every time for the same input. This makes it possible for anyone with access to the tool or encrypted data to easily reverse the encryption and retrieve original passwords.
This weakness puts client environments at risk, especially since the encrypted data often includes administrative credentials. The encryption does not follow modern security standards, and attackers do not need special tools or expertise to break it—only access to the files or application.
Analysis and Background
Network Detective, a product developed by RapidFire Tools (a Kaseya company), is designed to scan networks for vulnerabilities, misconfigurations, and compliance issues. It is used by managed service providers (MSPs), IT consultants, and internal IT departments to assess network health and generate reports. While commonly deployed as a standalone binary for one-off scans—often during sales or onboarding—Network Detective also supports scheduled, recurring scans in installed environments.
The application is typically configured via a step-by-step wizard, prompting users to define targets (e.g., IP ranges), scan types (e.g., HIPAA, PCI), and credentials for services such as Active Directory or VMware. This configuration is stored locally and reused for automated scans. Notably, the same binaries are used for both ad hoc and scheduled executions, meaning any vulnerabilities affect both deployment models equally.
Due to its ease of use and deep network visibility, the tool is often run with elevated privileges across production systems. Users implicitly trust the application to securely handle credentials and sensitive data. However, the issues discovered occur under default conditions, without requiring misuse or advanced manipulation—highlighting a significant risk for environments relying on the tool for security posture validation.
