CVE-2025-37176 is a command injection vulnerability identified in Hewlett Packard Enterprise's ArubaOS (AOS) versions 8.10.0.0 and 8.12.0.0. The flaw exists in the handling of package headers within the operating system, where an authenticated user with privileged access can alter these headers to inject arbitrary shell commands. This injection occurs because the input is not properly sanitized or validated before being processed by internal mechanisms, allowing the attacker to execute commands with the privileges of the affected component. The vulnerability requires the attacker to have high-level authentication credentials, meaning exploitation is limited to users who already have privileged access to the system. No user interaction is required beyond authentication. The CVSS v3.1 base score is 6.5, reflecting a medium severity level, with high impact on confidentiality and integrity but no impact on availability. Although no known exploits have been reported in the wild, the vulnerability poses a significant risk because it could allow malicious insiders or compromised accounts to execute unauthorized commands, potentially leading to data exfiltration, configuration manipulation, or further compromise of network infrastructure. ArubaOS is widely used in enterprise wireless networking equipment, including access points and controllers, making this vulnerability relevant for organizations relying on HPE Aruba products for their network connectivity and security.

For European organizations, the impact of CVE-2025-37176 can be substantial, especially for those heavily dependent on ArubaOS-based network infrastructure. Successful exploitation could lead to unauthorized command execution with elevated privileges, risking the confidentiality and integrity of sensitive data traversing or stored within the network devices. This could facilitate lateral movement within the network, unauthorized configuration changes, or deployment of persistent malicious code. While availability is not directly impacted, the indirect effects of compromised network devices could disrupt business operations. Sectors such as finance, telecommunications, government, and critical infrastructure operators in Europe are particularly at risk due to their reliance on secure and stable network environments. The requirement for privileged authentication limits the attack surface to insiders or attackers who have already compromised credentials, but this does not eliminate the risk, especially in environments with weak access controls or credential management practices.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Monitor HPE and ArubaOS vendor advisories closely and apply security patches or updates as soon as they become available to remediate the vulnerability. 2) Restrict privileged user access to ArubaOS devices using the principle of least privilege and enforce strong authentication mechanisms, including multi-factor authentication (MFA) where possible. 3) Implement rigorous logging and monitoring of privileged user activities on ArubaOS devices to detect anomalous command execution or configuration changes. 4) Conduct regular audits of user accounts and permissions to ensure that only authorized personnel have elevated access. 5) Employ network segmentation to limit the exposure of ArubaOS devices to trusted management networks and reduce the risk of lateral movement. 6) Use intrusion detection and prevention systems (IDS/IPS) tuned to detect suspicious command injection patterns or unusual device behavior. 7) Educate network administrators about the risks of this vulnerability and the importance of secure credential management.
