CVE-2025-37097 is a high-severity vulnerability affecting Hewlett Packard Enterprise's Insight Remote Support (IRS) software versions prior to 7.15.0.646. The vulnerability allows an unauthenticated attacker to cause a denial of service (DoS) condition against the IRS service. Specifically, the flaw is categorized under CWE-749, which relates to the improper handling of resource consumption, leading to potential exhaustion or disruption of service. The CVSS v3.1 base score is 7.5, indicating a high impact primarily on availability (A:H), with no impact on confidentiality or integrity. The attack vector is network-based (AV:N), requiring no privileges (PR:N) or user interaction (UI:N), and the scope remains unchanged (S:U). This means an attacker can remotely exploit the vulnerability without authentication or user involvement, making it relatively easy to execute. Although no known exploits are currently reported in the wild, the vulnerability's characteristics suggest that automated or scripted attacks could be developed to disrupt IRS services. Insight Remote Support is a tool used by organizations to monitor and manage HPE hardware and software environments, providing proactive support and issue resolution. A successful DoS attack could interrupt these support capabilities, potentially delaying incident response and system maintenance.

For European organizations relying on HPE Insight Remote Support, this vulnerability poses a significant risk to operational continuity. The DoS condition could disrupt remote monitoring and support functions, leading to delayed detection of hardware or software issues, increased downtime, and potential cascading effects on critical IT infrastructure. Industries with high dependency on HPE hardware, such as telecommunications, finance, healthcare, and government sectors, could experience service interruptions impacting business operations and regulatory compliance. Additionally, the lack of authentication requirement lowers the barrier for attackers, increasing the likelihood of opportunistic attacks. While confidentiality and integrity are not directly impacted, the availability disruption could indirectly affect data processing and service delivery, which is critical in environments with strict uptime requirements.

Organizations should prioritize upgrading HPE Insight Remote Support to version 7.15.0.646 or later, where the vulnerability is addressed. In the absence of an immediate patch, network-level mitigations should be implemented, such as restricting access to IRS services via firewall rules to trusted IP ranges only, and deploying intrusion detection/prevention systems (IDS/IPS) to monitor and block suspicious traffic patterns targeting IRS. Additionally, organizations should conduct regular network traffic analysis to detect anomalous activity indicative of DoS attempts. Implementing rate limiting and connection throttling on the IRS service endpoints can help mitigate resource exhaustion. It is also advisable to maintain robust incident response plans that include procedures for handling service disruptions. Finally, organizations should engage with HPE support channels for updates and advisories related to this vulnerability.
