CVE-2020-37210: SpotIE 2.9.5 DOS Vulnerability

CVE-2020-37210 Overview

SpotIE 2.9.5 contains a denial of service vulnerability in the registration key input that allows attackers to crash the application. The vulnerability exists due to improper input validation in the 'Key' field, where attackers can generate a 1000-character buffer payload and paste it into the registration key input to trigger an application crash.

Critical Impact

Local attackers can crash SpotIE 2.9.5 by providing an oversized input buffer to the registration key field, causing a denial of service condition.

Technical Details for CVE-2020-37210

Vulnerability Analysis

This vulnerability is classified as CWE-120 (Buffer Copy without Checking Size of Input), commonly known as a classic buffer overflow. The application fails to properly validate the size of user-supplied input before copying it into a fixed-size buffer. When a user provides an excessively long string (approximately 1000 characters) in the registration key field, the application attempts to process this input without appropriate boundary checks.

The local attack vector requires user interaction, as an attacker or victim must paste the malicious payload into the application's key registration field. While the vulnerability does not allow code execution or data exfiltration based on current analysis, it reliably crashes the application, disrupting normal operations.

Root Cause

The root cause is a classic buffer overflow (CWE-120) where the application copies user-supplied data from the registration key input field into a buffer without properly checking the size of the input. The Key field lacks appropriate length validation, allowing oversized input to overflow internal buffers and corrupt application memory, resulting in an unhandled exception and application crash.

Attack Vector

The attack vector is local, requiring an attacker to have access to the target system running SpotIE 2.9.5. The attacker must interact with the application directly by pasting a specially crafted 1000-character payload into the 'Key' registration field. This triggers the buffer overflow condition, causing the application to crash. No authentication is required to trigger this vulnerability, but user interaction is necessary to paste the payload.

The vulnerability can be exploited by generating a large buffer payload and inputting it into the registration key field. For detailed technical information about the exploit, refer to the Exploit-DB #47855 entry and the VulnCheck Advisory.

Detection Methods for CVE-2020-37210

Indicators of Compromise

• SpotIE application crashes or unexpected terminations occurring repeatedly
• Presence of crash dump files related to SpotIE 2.9.5 in system logs
• Evidence of large clipboard data being pasted into the application registration dialog

Detection Strategies

• Monitor system event logs for SpotIE application crash events and unhandled exception errors
• Implement endpoint detection rules to flag repeated application crashes of SpotIE 2.9.5
• Use process monitoring to detect clipboard operations involving unusually large text strings targeting SpotIE

Monitoring Recommendations

• Deploy endpoint monitoring solutions to track application stability for SpotIE 2.9.5
• Configure alerts for repeated SpotIE process terminations within short time intervals
• Review installed software inventory to identify systems running the vulnerable SpotIE 2.9.5 version

How to Mitigate CVE-2020-37210

Immediate Actions Required

• Identify all systems running SpotIE 2.9.5 and prioritize them for remediation
• Consider uninstalling or disabling SpotIE 2.9.5 if not critical for business operations
• Restrict user access to systems where SpotIE is installed to minimize exposure
• Review the NSA Auditor vendor page for updated software versions

Patch Information

No official patch information has been identified in the available CVE data. Users should monitor the vendor's website at nsauditor.com for security updates or newer versions of SpotIE that address this vulnerability. Consider upgrading to a later version if one becomes available that resolves this buffer overflow issue.

Workarounds

• Restrict access to the SpotIE registration dialog to prevent unauthorized input
• Implement application whitelisting to control what data can be pasted into SpotIE
• Use endpoint protection solutions to monitor and block suspicious application behavior
• Consider using alternative software that provides similar functionality without this vulnerability
