CVE-2025-46612 is a high-severity vulnerability affecting the Panel Designer dashboard in Airleader Master and Easy versions prior to 6.36. The vulnerability arises from an unrestricted file upload functionality exposed via the wizard/workspace.jsp endpoint. Specifically, authenticated users with administrator console access can upload arbitrary JSP files without proper validation or restrictions. This allows remote attackers to execute arbitrary commands on the affected server by uploading malicious JSP payloads. A critical factor enabling exploitation is the presence of weak default administrator credentials, which are easily guessable, effectively lowering the barrier for attackers to gain the necessary privileges to exploit this vulnerability. The vulnerability is categorized under CWE-434 (Unrestricted Upload of File with Dangerous Type), indicating a failure to properly restrict file types or validate uploaded content. The CVSS v3.1 base score is 7.2, reflecting high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and requiring high privileges but no user interaction. No known exploits are reported in the wild yet, and no official patches have been linked at the time of publication. This vulnerability could lead to full system compromise, data breaches, and disruption of services hosted on the affected Airleader platforms.

For European organizations using Airleader Master and Easy platforms, this vulnerability poses a significant risk. Successful exploitation can lead to unauthorized remote code execution, allowing attackers to gain control over critical infrastructure components. This can result in data theft, manipulation, or destruction, impacting confidentiality and integrity of sensitive information. Additionally, availability may be disrupted through service outages or ransomware deployment. The weak default credentials exacerbate the risk, as attackers can easily gain administrative access without sophisticated techniques. Organizations in sectors such as manufacturing, industrial automation, or utilities that rely on Airleader products for operational dashboards and control systems are particularly vulnerable. The compromise of such systems could have cascading effects on operational continuity, regulatory compliance, and safety. Furthermore, the ability to execute arbitrary commands remotely increases the threat of lateral movement within networks, potentially affecting broader IT and OT environments.

1. Immediately change all default administrator credentials to strong, unique passwords to prevent unauthorized access. 2. Restrict access to the administrator console using network segmentation, VPNs, or IP whitelisting to limit exposure. 3. Implement strict file upload validation controls, including whitelisting allowed file types and scanning uploaded files for malicious content. 4. Monitor logs and network traffic for suspicious activities related to file uploads or JSP execution. 5. Apply any available patches or updates from the vendor as soon as they are released. 6. Conduct regular security audits and penetration testing focusing on authentication mechanisms and file upload functionalities. 7. Employ web application firewalls (WAFs) with rules to detect and block attempts to upload or execute unauthorized files. 8. Educate administrators on the risks of weak credentials and enforce multi-factor authentication (MFA) where possible to enhance access security.
