Infiltrator Network Security Scanner is a legacy, free Windows-based utility designed to audit local network computers for vulnerabilities, configuration flaws, and active exploits. Developed by Infiltration Systems, it functions as both an information-gathering tool and a vulnerability assessment application.
However, the software is heavily outdated. It has known unpatched vulnerabilities, making it a liability rather than a security asset for modern environments. Key Capabilities & Features
When actively utilized, the software offers three primary functions:
Information Enumeration: Automatically uncovers a variety of local system data, including installed software, active users, hotfixes, open ports, storage drives, shared directories, NetBIOS tables, and SNMP tables.
Security Auditing: Analyzes remote systems for risky registry configurations, weak local password policies, unauthorized open ports, and missing security updates.
Built-in Network Utilities: Bundles roughly 15 to 19 minor networking utilities directly inside the interface, including ping sweeps, email tracing, brute-force cracking scripts, and WHOIS lookups. Operating Constraints & Interface
Platform Limitations: Built strictly as a local executable for older Windows operating systems ranging from Windows 98 and Windows 2000 up to Windows 7.
Automation: Supports execution from a local command-line interface to allow basic script automation and external task scheduling.
Reporting: Features a native report generator that formats discovered machine vulnerabilities into simple summaries or full compliance files. Significant Security Risks
Using Infiltrator in modern network infrastructure poses a direct risk:
Buffer Overflow Weakness (CVE-2018-25280): The core application suffers from a critical, unpatched validation flaw (CWE-120). If a user or local attacker inputs an oversized string (exceeding 6,000 bytes) into the Scan Target field and runs a scan, it causes an unhandled memory overwrite that triggers a total application crash (Denial of Service). Modern Alternatives
Because Infiltrator relies on an old architecture, security teams typically replace it with modern, cloud-native, or actively maintained exposure management frameworks:
