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 arises from insufficient validation of package headers, which an authenticated user with privileged access can manipulate to inject arbitrary shell commands. This vulnerability falls under CWE-77 (Improper Neutralization of Special Elements used in a Command), indicating that the system fails to properly sanitize input before executing commands. Exploiting this vulnerability allows an attacker to execute arbitrary commands with the privileges of the impacted mechanism, potentially leading to unauthorized access to sensitive data or alteration of system configurations. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), and high privileges (PR:H), but no user interaction (UI:N). The scope remains unchanged (S:U), and the impact on confidentiality and integrity is high (C:H, I:H), while availability is unaffected (A:N). No known exploits have been reported in the wild, but the vulnerability poses a significant risk in environments where privileged user accounts could be compromised or misused. ArubaOS is widely used in enterprise wireless networking solutions, making this vulnerability particularly relevant to organizations relying on HPE's network infrastructure products.

For European organizations, the impact of CVE-2025-37176 can be substantial, especially for those relying on ArubaOS for critical network infrastructure such as wireless access points and controllers. Successful exploitation could allow attackers with privileged credentials to execute arbitrary commands, potentially leading to unauthorized data access, manipulation of network configurations, and lateral movement within the network. This could compromise the confidentiality and integrity of sensitive information and disrupt secure network operations. Given the medium severity and the requirement for privileged authentication, the threat is more likely to arise from insider threats or attackers who have already gained elevated access. The absence of availability impact reduces the likelihood of direct denial-of-service attacks but does not diminish the risk of stealthy, persistent compromise. European sectors such as finance, government, healthcare, and critical infrastructure, which often deploy ArubaOS solutions, could face increased risks of espionage, data breaches, or sabotage if this vulnerability is exploited.

1. Apply official patches or updates from Hewlett Packard Enterprise as soon as they become available to address this vulnerability. 2. Restrict privileged user access to ArubaOS management interfaces using strict role-based access controls and multi-factor authentication to reduce the risk of credential compromise or misuse. 3. Implement network segmentation to isolate ArubaOS management traffic from general user traffic and limit exposure. 4. Monitor logs and network traffic for unusual command executions or changes in package headers that could indicate exploitation attempts. 5. Conduct regular audits of privileged accounts and their activities to detect potential insider threats. 6. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect command injection patterns specific to ArubaOS. 7. Educate administrators on secure configuration practices and the risks associated with elevated privileges in ArubaOS environments.
