CVE-2019-25594: ASPRunner.NET 10.1 DoS Vulnerability

CVE-2019-25594 Overview

CVE-2019-25594 is a denial of service vulnerability affecting ASPRunner.NET 10.1. The vulnerability allows local attackers to crash the application by supplying an excessively long string in the table name field during database table creation. Specifically, attackers can input a buffer of 10,000 characters in the table name parameter to trigger an application crash.

Critical Impact

Local attackers can cause complete application unavailability by exploiting improper input validation in the table name field, leading to denial of service conditions.

Technical Details for CVE-2019-25594

Vulnerability Analysis

This denial of service vulnerability stems from improper handling of user-supplied input in the table name field of ASPRunner.NET. When a user provides an excessively long string (approximately 10,000 characters) as a table name during the database table creation process, the application fails to properly validate the input length, resulting in an application crash.

The vulnerability is classified under CWE-807 (Reliance on Untrusted Inputs in a Security Decision), indicating that the application makes security-relevant decisions based on user input without adequate validation. The local attack vector requires the attacker to have access to the ASPRunner.NET application interface to exploit this flaw.

Root Cause

The root cause of this vulnerability is insufficient input validation in ASPRunner.NET's table name handling functionality. The application does not implement proper boundary checks on the length of user-supplied table names, allowing excessively long strings to be processed. This lack of input sanitization leads to resource exhaustion or buffer-related issues that cause the application to crash.

Attack Vector

The attack is executed locally by an attacker with access to the ASPRunner.NET application. The exploitation process involves:

1. Accessing the database table creation functionality within ASPRunner.NET
2. Entering an excessively long string (10,000+ characters) in the table name field
3. Submitting the form to trigger the vulnerability
4. The application crashes due to improper handling of the oversized input

The vulnerability requires no special privileges to exploit, and no user interaction beyond the attacker's own actions is needed. The impact is limited to availability, with no direct effect on confidentiality or integrity.

Detection Methods for CVE-2019-25594

Indicators of Compromise

• Unexpected ASPRunner.NET application crashes or service interruptions
• Application logs showing errors related to table name processing or buffer overflows
• Evidence of unusually long input strings in request logs or database operation logs

Detection Strategies

• Monitor ASPRunner.NET application stability for unexpected crashes during table creation operations
• Implement input validation monitoring to detect attempts to submit excessively long strings to form fields
• Review application logs for error messages related to table name parameters or memory allocation failures

Monitoring Recommendations

• Enable detailed logging for ASPRunner.NET application operations
• Set up alerts for application crashes or unexpected restarts
• Monitor system resource utilization for anomalies during database configuration activities

How to Mitigate CVE-2019-25594

Immediate Actions Required

• Upgrade ASPRunner.NET to the latest available version from Xlinesoft
• Implement input length validation at the application level to restrict table name field size
• Restrict access to the ASPRunner.NET application to authorized users only

Patch Information

Users should check the Xlinesoft Download Page for updated versions of ASPRunner.NET that address this vulnerability. Consult the VulnCheck Advisory for additional remediation guidance.

Workarounds

• Implement server-side input validation to limit table name field length to a reasonable maximum (e.g., 128 characters)
• Deploy a web application firewall (WAF) rule to block requests containing excessively long parameter values
• Restrict local access to the ASPRunner.NET application to trusted administrators only
