CVE-2019-25594 in ASPRunner.NET
Summary
by MITRE • 03/22/2026
ASPRunner.NET 10.1 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an excessively long string in the table name field. Attackers can input a buffer of 10000 characters in the table name parameter during database table creation to trigger an application crash.

The vulnerability identified as CVE-2019-25594 represents a critical denial of service flaw within ASPRunner.NET version 10.1 that stems from inadequate input validation mechanisms. This weakness specifically targets the table name parameter during database table creation processes, creating an exploitable condition where malicious actors can deliberately crash the application through buffer overflow techniques. The vulnerability manifests when attackers supply an excessively long string of 10000 characters in the table name field, which exceeds the application's expected input limits and causes memory corruption that leads to application termination.
From a technical perspective, this vulnerability aligns with CWE-121, which describes buffer overflow conditions where insufficient bounds checking allows attackers to write beyond allocated memory regions. The flaw operates at the input sanitization layer where the application fails to implement proper string length validation before processing user-supplied data. The buffer overflow occurs during the database table creation routine when the application attempts to process the malformed table name parameter without adequate boundary checks, resulting in stack corruption that ultimately crashes the entire ASPRunner.NET process.
The operational impact of this vulnerability extends beyond simple application disruption as it provides local attackers with a reliable method to cause service unavailability for legitimate users. Since the vulnerability requires only a single parameter modification during table creation, it represents a low-effort, high-impact attack vector that can be exploited repeatedly to maintain service disruption. The local privilege requirement means that attackers must already have access to the system to exploit this flaw, but once achieved, the impact can be severe as it affects the core application functionality and potentially impacts database operations that depend on ASPRunner.NET for data management.
Security practitioners should consider this vulnerability in the context of the MITRE ATT&CK framework where it maps to the T1499.004 technique for network denial of service, and more specifically to T1059.001 for command and scripting interpreter usage. The vulnerability demonstrates poor input validation practices that align with the broader category of insecure coding patterns that frequently appear in web application frameworks. Organizations should implement immediate mitigations including input length validation, character set restrictions, and proper error handling mechanisms that prevent buffer overflow conditions from occurring during database table creation processes. Additionally, regular security assessments should be conducted to identify similar input validation gaps in other application components that could present similar attack surfaces.
