Advantech iView Remote Code Execution via SQL Injection in SNMP Management Tool.

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2022-50593

Advantech iView is a network management system designed to monitor and manage industrial network devices. Such management platforms are frequently deployed as web-based interfaces that are either directly exposed to the internet or reachable via external-facing management gateways, making them a common target for remote access in industrial and enterprise network environments.

Horizon Alert

Summary of the vulnerability and why it matters

Advantech iView software contains a vulnerability that allows unauthenticated remote attackers to execute arbitrary code with administrator privileges by exploiting a SQL injection flaw. This impacts industrial network management systems, potentially leading to full system compromise.

Flaw in network tool allows remote code execution.
Affects industrial management systems, a key target.
Confirm relevance and exposure of affected systems.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by remotely accessing the vulnerable management tool over the network without needing any credentials. They would then send a specially crafted request to a specific network endpoint, targeting a parameter that is susceptible to SQL injection. This injection allows the attacker to bypass security checks and ultimately gain control of the system with administrator privileges.

No authentication required for access.
SQL injection via ‘search_term’ parameter.
Remote code execution with admin rights.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an unauthenticated remote attacker to execute arbitrary code with administrator privileges on affected systems. This is possible when the vulnerable SNMP management tool is accessible and the 'search_term' parameter is manipulated to inject SQL commands, leading to a compromise of the underlying operating system and its services.

Administrator privileges and system access.
Remote attackers could exploit SQL injection.
Compromise of industrial control systems.

Operational Fix

Recommended remediation, mitigation, and detection steps

Teams responsible for managing Advantech iView deployments, likely including infrastructure or platform teams overseeing industrial control systems or network management tools, must first identify all instances of the affected software. Confirming which deployments are externally reachable or critical to operations will inform risk assessment and prioritization. Engaging the accountable system owner or vendor-management team is crucial for planning coordinated remediation actions.

Identify system ownership and critical assets.
Verify external reachability and business impact.
Plan coordinated remediation with owners.

Frequently asked questions

What is Advantech iView?

Advantech iView is a software platform used for monitoring and managing industrial network devices. It functions as a centralized hub that administrators use to oversee network health and configurations. Because it manages infrastructure, it is typically deployed as a web-based interface that connects directly to the network equipment it monitors.

What does CVE-2022-50593 mean?

This CVE describes a critical security weakness involving two flaws: missing authentication (CWE-306) and SQL injection (CWE-89). Together, these allow an attacker to skip the login process and send malicious commands through the 'search_term' field in a specific network tool. This chain reaction effectively gives an unauthorized person full control over the application with administrative rights.

How can an attacker trigger this vulnerability?

An attacker triggers this by sending a specially crafted request to the 'NetworkServlet' endpoint. The bug requires no prior login credentials or interaction from a user. Notably, simply accessing the web interface is not enough; the attacker must specifically target the 'search_term' parameter with malicious SQL syntax to successfully bypass security checks and execute unauthorized code.

Is my system at risk?

If you use Advantech iView versions before 5.7.04 build 6425, you are affected. Halo Surface Signal notes that because iView is often deployed as a web-based management interface, these platforms are frequently reachable via external-facing gateways or even the public internet, making them attractive targets for remote attackers looking to gain access to industrial network environments.

How should I respond to CVE-2022-50593?

First, locate all running instances of Advantech iView within your environment to understand your footprint. Next, prioritize systems that are connected to the internet or accessible from outside your local network for immediate review. Coordinate with your system owners to plan the necessary updates to the latest version, as this is the primary way to remove the vulnerability and protect the software from unauthorized administrative access.
