CVE-2025-27082 is an arbitrary file write vulnerability found in Hewlett Packard Enterprise's Aruba Networking AOS operating systems, specifically versions 10.7.0.0, 10.4.0.0, 8.12.0.0, and 8.10.0.0. The flaw exists in the web-based management interface of both AOS-10 Gateway and AOS-8 Controller/Mobility Conductor platforms. It allows an attacker who has authenticated with high privileges to upload arbitrary files to the system, which can then be executed to run arbitrary commands on the underlying host OS. This vulnerability stems from improper validation or restrictions on file uploads, categorized under CWE-434, which involves unrestricted upload of files with dangerous types. Exploitation does not require user interaction but does require authenticated access with elevated privileges, making insider threats or compromised credentials a key risk vector. The vulnerability impacts confidentiality, integrity, and availability by enabling attackers to execute code remotely, potentially leading to full system compromise, data theft, or disruption of network services. No public patches or exploit code are currently available, but the vulnerability is publicly disclosed and rated with a CVSS 3.1 score of 7.2, indicating high severity. The affected products are widely deployed in enterprise wireless and mobility management environments, making this a critical concern for organizations relying on HPE Aruba infrastructure.

The impact of CVE-2025-27082 is significant for organizations using affected HPE Aruba Networking AOS devices. Successful exploitation can lead to full system compromise of critical network infrastructure components, allowing attackers to execute arbitrary commands at the operating system level. This can result in unauthorized access to sensitive network configurations, interception or manipulation of network traffic, disruption of wireless services, and potential lateral movement within the enterprise network. The compromise of mobility controllers and gateways can severely degrade network availability and integrity, impacting business operations reliant on wireless connectivity. Additionally, attackers could implant persistent backdoors or malware, leading to long-term security breaches. Given the role of these devices in managing enterprise wireless environments, the vulnerability poses a high risk to confidentiality, integrity, and availability of network services. Organizations may face regulatory compliance issues and reputational damage if exploited in targeted attacks.

To mitigate CVE-2025-27082, organizations should: 1) Immediately verify if their HPE Aruba AOS devices run affected versions (10.7.0.0, 10.4.0.0, 8.12.0.0, 8.10.0.0) and prioritize upgrading to patched versions once available from HPE. 2) Restrict access to the web-based management interface to trusted administrative networks and enforce strong multi-factor authentication to reduce risk of credential compromise. 3) Monitor administrative access logs for unusual authentication patterns or file upload attempts. 4) Implement network segmentation to isolate management interfaces from general user networks. 5) Employ application-layer firewalls or web application firewalls (WAFs) to detect and block suspicious file upload activities. 6) Conduct regular security audits and vulnerability scans focused on management interfaces. 7) Educate administrators on the risks of credential theft and enforce least privilege principles for management accounts. 8) If patches are not yet available, consider temporary compensating controls such as disabling file upload features or limiting administrative access until remediation is possible. These steps go beyond generic advice by focusing on access control hardening, monitoring, and network segmentation specific to the affected management interfaces.
