CVE-2020-37138: 10-Strike Network Inventory RCE Flaw

CVE-2020-37138 Overview

10-Strike Network Inventory Explorer 9.03 contains a buffer overflow vulnerability in the file import functionality that allows remote attackers to execute arbitrary code. Attackers can craft a malicious text file with a carefully constructed payload to trigger a stack-based buffer overflow and bypass data execution prevention through a ROP chain.

Critical Impact

This stack-based buffer overflow vulnerability enables arbitrary code execution through malicious file imports, potentially allowing complete system compromise when a user opens a crafted file.

Technical Details for CVE-2020-37138

Vulnerability Analysis

This vulnerability is classified under CWE-121 (Stack-based Buffer Overflow), which occurs when a program writes data beyond the allocated buffer on the stack. In the case of 10-Strike Network Inventory Explorer 9.03, the file import functionality fails to properly validate the length of input data from imported text files before copying it into a fixed-size stack buffer.

The vulnerability requires user interaction—specifically, the target must open or import a maliciously crafted file. Once triggered, the overflow overwrites adjacent memory on the stack, including saved return addresses and Structured Exception Handler (SEH) records. The exploitation technique documented involves using a ROP (Return-Oriented Programming) chain to bypass Data Execution Prevention (DEP) protections, allowing the attacker to achieve arbitrary code execution within the context of the application.

Root Cause

The root cause stems from improper input validation and unsafe memory handling in the file import routine. The application allocates a fixed-size buffer on the stack and copies imported data without verifying that the data length does not exceed the buffer's capacity. This lack of bounds checking allows attackers to supply oversized input that overflows the buffer and corrupts critical stack structures.

Attack Vector

The attack vector is local, requiring the attacker to deliver a malicious file to the victim system and convince the user to import it through the 10-Strike Network Inventory Explorer application. The attack flow typically involves:

1. The attacker crafts a malicious text file containing an oversized payload designed to overflow the stack buffer
2. The payload includes a ROP chain to bypass DEP protection mechanisms
3. The victim imports the malicious file using the application's file import functionality
4. The buffer overflow overwrites the SEH records and return addresses on the stack
5. Control flow is redirected through the ROP chain to execute arbitrary code

The exploitation does not require authentication or elevated privileges, but does require user interaction to trigger the vulnerable code path. Technical details and proof-of-concept information are available through the Exploit-DB #48264 entry and the VulnCheck Advisory for SEHROP.

Detection Methods for CVE-2020-37138

Indicators of Compromise

• Presence of unusually large or malformed text files in directories associated with 10-Strike Network Inventory Explorer
• Application crashes or unexpected termination of NetInvExplorer.exe processes
• Evidence of shell code execution or suspicious child processes spawned from the application
• Anomalous memory access patterns or DEP violation events in Windows Event Logs

Detection Strategies

• Monitor for application crashes in 10-Strike Network Inventory Explorer that may indicate exploitation attempts
• Implement file integrity monitoring on directories where inventory files are stored
• Deploy endpoint detection rules to identify ROP chain patterns or stack pivot operations
• Analyze imported files for suspicious patterns including long strings of repeated characters or NOP sleds

Monitoring Recommendations

• Enable crash dump collection for the 10-Strike Network Inventory Explorer application to capture exploitation attempts
• Configure Windows Event Forwarding to centralize Application Error events related to the affected application
• Implement SentinelOne's behavioral AI detection to identify buffer overflow exploitation techniques in real-time
• Monitor for unusual process creation events where NetInvExplorer.exe is the parent process

How to Mitigate CVE-2020-37138

Immediate Actions Required

• Avoid importing text files from untrusted or unknown sources into 10-Strike Network Inventory Explorer
• Restrict user permissions to limit who can access the vulnerable file import functionality
• Consider temporarily disabling or restricting access to the application until a patch is available
• Deploy application whitelisting to prevent unauthorized code execution from exploitation

Patch Information

No official vendor patch information is currently available in the CVE data. Organizations should monitor the 10-Strike Network Inventory Explorer product page for security updates. Contact the vendor directly for remediation guidance and timeline for security fixes.

Workarounds

• Implement network segmentation to limit lateral movement if a workstation running the vulnerable application is compromised
• Apply the principle of least privilege to accounts that use 10-Strike Network Inventory Explorer
• Use file scanning solutions to inspect imported files before processing them with the application
• Enable Windows Exploit Protection features such as mandatory ASLR and CFG for additional defense-in-depth

Organizations should consult the VulnCheck Advisory for SEHROP for additional technical guidance on detection and mitigation strategies.
