Critical Flaws Found in Advantech Wi-Fi Access Points – Update Now
Title: Critical Vulnerabilities Discovered in Advantech EKI Wireless Access Points: Immediate Action Required
Introduction
A recent security analysis has revealed nearly two dozen vulnerabilities in Advantech EKI industrial-grade wireless access point devices, with some flaws posing severe risks, including unauthorized remote code execution. Cybersecurity firm Nozomi Networks highlighted the potential for these vulnerabilities to compromise device integrity and confidentiality, urging users to update their firmware promptly. This article delves into the critical vulnerabilities discovered and the necessary steps to mitigate associated risks.
Understanding the Security Risks
The vulnerabilities identified in Advantech EKI wireless access points can potentially allow attackers to bypass authentication protocols and execute code with root privileges. According to Nozomi Networks, these weaknesses could fully compromise the affected devices, leading to significant security breaches.
Firmware Updates to Address Vulnerabilities
Following a responsible disclosure process, Advantech has released firmware updates to address these issues. The following versions are now available:
- 1.6.5 for EKI-6333AC-2G and EKI-6333AC-2GD
- 1.2.2 for EKI-6333AC-1GPO
Users are strongly advised to upgrade to these firmware versions to enhance security and protect against potential exploits.
Critical Vulnerabilities and Their Implications
Among the identified vulnerabilities, six have been classified as critical, allowing malicious actors to:
- Implant backdoors for persistent access to internal resources
- Trigger denial-of-service (DoS) conditions
- Repurpose infected devices as Linux workstations for further network penetration
The critical flaws, including CVE-2024-50370 through CVE-2024-50374 and CVE-2024-50375, all have a CVSS score of 9.8, indicating their severity. These vulnerabilities primarily relate to improper neutralization of special elements in operating system (OS) commands and missing authentication for essential functions.
Chaining Vulnerabilities for Greater Exploits
Another significant concern is CVE-2024-50376, a cross-site scripting (XSS) vulnerability with a CVSS score of 7.3. This flaw can be exploited in conjunction with CVE-2024-50359, another OS command injection vulnerability, to achieve arbitrary code execution remotely. For successful exploitation, an attacker must be within physical proximity to the vulnerable Advantech access point.
The attack can occur when an administrator accesses the “Wi-Fi Analyzer” section of the web application, allowing the attacker to embed malicious information into the page without proper sanitization checks.
How Attackers Can Exploit These Vulnerabilities
An attacker could broadcast malicious data through a rogue access point, such as a crafted SSID containing a JavaScript payload. This would enable the execution of arbitrary JavaScript code in the victim’s browser, potentially leading to command injection with root privileges. Such access could allow attackers to:
- Gain remote control over the compromised device
- Execute commands
- Extract sensitive data or deploy additional malware
Conclusion and Call to Action
The discovery of these critical vulnerabilities in Advantech EKI wireless access points underscores the importance of prompt firmware updates and ongoing vigilance in cybersecurity practices. Users are encouraged to stay informed about security threats and consider implementing additional protective measures.
