CVE-2025-4633 is a security vulnerability identified in the JCT Airpointer product, specifically version 2.4.107-2. The vulnerability stems from the presence of hard-coded default credentials embedded within the web portal interface of the Airpointer device. This flaw allows an unauthenticated attacker to gain access to the system by logging in with these default credentials without any prior authentication or user interaction. The vulnerability is classified under CWE-798, which relates to the use of hard-coded credentials, a common security weakness that can lead to unauthorized access. The CVSS v3.1 base score for this vulnerability is 6.5, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N) reveals that the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality and integrity but not availability. Although no known exploits are currently reported in the wild, the presence of default credentials inherently increases the risk of unauthorized access, potentially allowing attackers to view sensitive information or alter system configurations. Since the vulnerability affects the web portal, it is likely that the Airpointer device is used in environments where remote monitoring or control is essential, making the exposure of credentials particularly critical. The lack of available patches at the time of reporting further emphasizes the need for immediate mitigation steps by users of the affected version.

For European organizations, the exploitation of CVE-2025-4633 could lead to unauthorized access to Airpointer devices, which may be used in environmental monitoring, industrial control, or other critical infrastructure sectors. The confidentiality impact means sensitive data collected or processed by the device could be exposed, potentially violating data protection regulations such as GDPR. Integrity impact implies attackers could manipulate data or device settings, leading to incorrect readings or operational disruptions. While availability is not directly affected, the indirect consequences of compromised data integrity could affect decision-making processes or regulatory compliance. Organizations relying on Airpointer devices for environmental data or operational monitoring may face reputational damage, regulatory penalties, or operational inefficiencies if this vulnerability is exploited. The ease of exploitation (no authentication or user interaction required) increases the risk, especially if devices are accessible over the internet or poorly segmented networks. Given the medium severity, the threat is significant but not critical; however, the potential for escalation or chaining with other vulnerabilities could increase overall risk.

To mitigate this vulnerability, European organizations using Airpointer version 2.4.107-2 should immediately implement the following measures: 1) Restrict network access to the Airpointer web portal by implementing strict firewall rules and network segmentation to limit exposure to trusted internal networks only. 2) Change any default or hard-coded credentials if possible, or disable the web portal interface until a vendor patch is available. 3) Monitor network traffic and device logs for any unauthorized access attempts or suspicious activities targeting the Airpointer devices. 4) Engage with the vendor (JCT) to obtain guidance on patches or firmware updates addressing this vulnerability and apply them promptly once released. 5) Employ multi-factor authentication (MFA) on management interfaces if supported, to add an additional layer of security. 6) Conduct regular security assessments and penetration testing focusing on IoT and embedded devices to identify similar weaknesses. 7) Educate relevant personnel about the risks of hard-coded credentials and enforce policies to avoid deploying devices with default passwords in production environments.
