CVE-2025-53577 is a critical remote code inclusion vulnerability classified under CWE-94 (Improper Control of Generation of Code) affecting thehp Global DNS product up to version 3.1.0. This vulnerability allows an unauthenticated attacker to execute arbitrary code remotely on the affected system without any user interaction. The root cause lies in insufficient validation or sanitization of input that is used to dynamically generate or include code within the Global DNS application. By exploiting this flaw, an attacker can inject malicious code that the system will execute, potentially leading to full system compromise. The CVSS v3.1 score of 10.0 reflects the highest severity, indicating that the vulnerability is exploitable over the network with no privileges or user interaction required, and it impacts confidentiality, integrity, and availability at a complete level. Although no known exploits are currently reported in the wild, the critical nature and ease of exploitation make this a high-priority issue. The lack of available patches at the time of publication further increases the risk for organizations using this product. Given that Global DNS is a DNS management or resolution product, compromise could allow attackers to manipulate DNS queries, redirect traffic, intercept sensitive data, or disrupt network services.

For European organizations, the impact of this vulnerability could be severe. DNS infrastructure is a foundational component of network operations, and compromise could lead to widespread service disruption, data interception, or redirection to malicious sites. Confidentiality breaches could expose sensitive corporate or personal data, while integrity violations could undermine trust in network communications. Availability impacts could result in denial of service, affecting business continuity. Organizations relying on thehp Global DNS for internal or external DNS resolution are at risk of having their DNS infrastructure hijacked or manipulated. This could affect sectors such as finance, government, telecommunications, and critical infrastructure, where DNS reliability and security are paramount. Additionally, the vulnerability could be leveraged as a foothold for lateral movement within networks, increasing the risk of broader compromise.

Immediate mitigation steps include isolating the affected Global DNS servers from external networks to reduce exposure until a patch is available. Network-level controls such as firewall rules should restrict access to the DNS management interfaces to trusted IP addresses only. Implementing strict input validation and sanitization on any user-supplied data related to DNS configuration can reduce risk if custom configurations are used. Monitoring DNS traffic for anomalies and unexpected query patterns can help detect exploitation attempts. Organizations should also prepare incident response plans specific to DNS compromise scenarios. Since no patches are currently available, consider deploying compensating controls such as DNSSEC to protect DNS integrity and using alternative DNS services temporarily. Regular backups of DNS configurations and system states will facilitate recovery if compromise occurs. Finally, maintain close communication with the vendor for updates on patches or workarounds.
