CVE-2019-25319 in Domain Quester Pro
Summary
by MITRE • 02/13/2026
Domain Quester Pro 6.02 contains a stack overflow vulnerability that allows remote attackers to execute arbitrary code by overwriting Structured Exception Handler (SEH) registers. Attackers can craft a malicious payload targeting the 'Domain Name Keywords' input field to trigger an access violation and execute a bind shell on port 9999.

The vulnerability identified as CVE-2019-25319 represents a critical stack overflow flaw in Domain Quester Pro version 6.02 that exposes the application to remote code execution attacks. This vulnerability specifically targets the application's handling of user input through the 'Domain Name Keywords' field, creating a pathway for malicious actors to manipulate the program's execution flow. The flaw exists within the software's structured exception handling mechanism, making it particularly dangerous as it allows attackers to directly overwrite SEH registers during program execution.
The technical implementation of this vulnerability leverages classic stack buffer overflow techniques combined with structured exception handler manipulation. When the application processes a specially crafted payload through the 'Domain Name Keywords' input field, it fails to properly validate input length and boundaries, leading to memory corruption that overwrites the structured exception handler chain. This manipulation enables attackers to redirect program execution to malicious code locations, effectively bypassing standard security protections. The vulnerability operates at the kernel level memory management, where the application's stack-based buffer overflow directly affects the SEH frame structure, creating an exploitable condition that can be leveraged for privilege escalation.
The operational impact of this vulnerability extends beyond simple remote code execution to encompass full system compromise capabilities. Attackers can utilize this flaw to establish persistent backdoor access through the bind shell on port 9999, which provides them with continuous control over the affected system. The vulnerability's remote exploitability means that attackers do not require physical access or local credentials to achieve their objectives, making it particularly dangerous in networked environments where the application might be exposed to external traffic. This type of vulnerability directly maps to attack patterns described in the attack tree methodology, where the exploitation chain follows the sequence of input manipulation, buffer overflow, and privilege escalation to achieve system compromise.
Mitigation strategies for CVE-2019-25319 should focus on immediate software patching and network-level defenses to prevent exploitation attempts. Organizations should prioritize updating to the latest version of Domain Quester Pro that addresses this specific buffer overflow vulnerability, as the vendor has likely implemented proper input validation and stack protection mechanisms. Network segmentation and firewall rules should be configured to restrict access to the application's network interfaces, particularly blocking external connections to port 9999 where the bind shell would be established. Additionally, implementing application whitelisting controls and runtime protection mechanisms can help detect and prevent exploitation attempts. The vulnerability aligns with CWE-121, which describes stack-based buffer overflow conditions, and represents a classic example of how improper input validation can lead to arbitrary code execution. From an ATT&CK framework perspective, this vulnerability maps to T1059.007 for remote code execution and T1071.004 for application layer protocol usage, indicating the need for comprehensive network monitoring and endpoint protection measures.
