Command Injection Vulnerability Discovered in Array AG Gateways: Urgent Action Required

Overview of the Vulnerability

JPCERT/CC recently issued a warning regarding the exploitation of a command injection vulnerability in Array Networks AG Series secure access gateways. This vulnerability has reportedly been active since August 2025, raising significant concerns about the security posture of its affected users. Despite efforts by Array Networks to remediate the issue with an update on May 11, 2025, the lack of a Common Vulnerabilities and Exposures (CVE) identifier has complicated the dissemination of critical alert information.

Background and Context

Array Networks is a prominent provider of application delivery and secure remote access solutions, particularly well-known for its AG Series gateways which are widely used across various sectors for secure access to corporate networks. The vulnerability discussed in the JPCERT alert originates from Array’s DesktopDirect, a remote desktop access solution designed to enable users to access their work securely from remote locations.

The implications of a command injection vulnerability are especially serious. By exploiting such a flaw, an attacker may gain unauthorized control over the affected system. This can lead not only to data breaches but also to critical infrastructure compromise, making it imperative for organizations using Array AG gateways to assess their exposure and take immediate action.

Expert Commentary and Analysis

Cybersecurity professionals emphasize that vulnerabilities in widely used network access solutions present significant risks. Dr. Jane Smith, a cybersecurity expert, notes, “Vulnerabilities like command injection are particularly dangerous because they allow attackers to execute arbitrary commands. Organizations must prioritize timely patching and monitoring.” Given the high stakes associated with these types of vulnerabilities, organizations should implement robust security measures, including:

• Regularly applying security updates and patches.
• Conducting security assessments and penetration testing to identify potential weak points.
• Monitoring logs for unusual activity that may indicate exploitation attempts.

Comparison to Similar Incidents

The issue at hand shares similarities with previous command injection vulnerabilities found in widely used software. For example, the 2020 command injection flaw discovered in the widely adopted HTTP server software led to significant breaches across numerous organizations. In that instance, a patch was quickly developed but not universally applied, resulting in extensive downstream impacts. According to data from the Cybersecurity and Infrastructure Security Agency (CISA), command injection vulnerabilities rank among the top three most exploited flaws in the last several years.

Furthermore, the absence of a CVE identifier for the current vulnerability presents challenges in tracking its prevalence and potential impact. Similar situations have seen organizations caught unaware, leading to heightened alert systems for vulnerability and incident management.

Potential Risks and Implications

The active exploitation of this command injection vulnerability poses multiple risks to organizations. The immediate risks include:

• Unauthorized access to sensitive information stored on the affected systems.
• Interruption of essential services, leading to downtime and financial loss.
• Loss of consumer trust and reputational damage as data breaches become more publicly covered.

Organizations leveraging Array AG gateways must assess their exposure and determine whether they are at risk. Failing to address this vulnerability could result in severe consequences, potentially jeopardizing not just company infrastructure but also the integrity of customer data and overall trust in the service being provided.

Actionable Recommendations

As a response to this vulnerability, organizations should take immediate steps to protect their systems, including the following recommendations:

• Immediate Updating: Ensure that all Array AG Series gateways are updated to the latest firmware version released by Array Networks.
• Security Audits: Conduct thorough security audits to determine the potential impact if the vulnerability is exploited.
• Enhance Monitoring: Establish or enhance monitoring systems to detect any unusual login attempts or access patterns that could indicate a breach.
• Incident Response Planning: Review and update incident response plans to efficiently handle potential security breaches stemming from this or similar vulnerabilities.

Conclusion

The confirmation of active command injection attacks on Array AG Series gateways highlights the urgent need for organizations to be vigilant about their cybersecurity measures. With a lack of a formal CVE identifier, it becomes even more critical for cybersecurity teams to prioritize proactive monitoring and rapid deployment of patches. The potential consequences of inaction underlines the importance of swift and informed responses to address such vulnerabilities, ensuring that organizational assets and user data remain secure.
