CVE-2025-4635

Vulnerability

Overview

CVE-2025-4635 describes a security flaw found in JCT NextGen AQMS airpointer 2D. A user with administrative privileges within the web portal can manipulate the Diagnostics module to achieve remote code execution (RCE) on the local device. The compromised code runs with low-privileged user rights, limiting direct system-wide impact but enabling further exploitation [1].

Attack

Vector and Prerequisites

The vulnerability requires administrative-level credentials for the web portal, making it a post-authentication attack vector. An attacker who has already obtained admin rights can misuse the Diagnostics module's inputs to inject and execute arbitrary commands or scripts. The attack is performed remotely over the network, targeting the exposed web interface of the airpointer 2D device [1].

Impact

Successful exploitation grants the attacker the ability to execute code as a low-privileged user on the device. While the immediate impact is mitigated by the low integrity level, the attacker could leverage this foothold to escalate privileges, access sensitive monitoring data, or disrupt the air quality measurement functions of the system [1].

Mitigation

As of the publication date, JCT NextGen AQMS has not released a security advisory or patch. Organizations should restrict administrative access to the web portal using strong authentication and network segmentation. Monitor for unauthorized administrative activity and apply vendor updates when they become available [1].
