A critical security vulnerability (CVE-2025-2727) has been identified in H3C Magic NX30 Pro routers running firmware versions up to V100R007. This command injection flaw allows remote attackers to execute arbitrary commands through the device’s HTTP POST request handler. With a CVSS v3.1 score of 8.8 (High severity), this vulnerability poses significant risks to organizations using affected devices.
Technical Analysis
The vulnerability resides in the HTTP POST request handler component of H3C Magic NX30 Pro routers. The /api/wizard/getNetworkStatus endpoint fails to properly sanitize user-supplied input, allowing command injection attacks. This security gap enables attackers to execute arbitrary commands with the web server’s privileges, potentially leading to complete system compromise.
Security researchers have classified this vulnerability under CWE-77 (Improper Neutralization of Special Elements used in a Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The public disclosure includes technical details about the exploit mechanism, though we refrain from providing specific exploitation guidance without proper authorization.
Impact Assessment
Successful exploitation of CVE-2025-2727 could lead to complete system compromise, giving attackers unauthorized access to network resources. The vulnerability’s remote exploitation capability without authentication makes it particularly dangerous, as it could facilitate lateral movement within affected networks.
Organizations using vulnerable H3C Magic NX30 Pro routers face several potential consequences including data exfiltration, persistent backdoor installation, and service disruption. The public availability of exploit information combined with the vendor’s unresponsiveness to disclosure attempts significantly increases the risk of widespread exploitation.
Detection and Mitigation
Network defenders should monitor for unusual HTTP POST requests to the /api/wizard/getNetworkStatus endpoint and unexpected command execution patterns in router logs. Implementing strict input validation for management interfaces and restricting access to router management interfaces can help reduce the attack surface.
While awaiting official patches from the vendor, organizations should consider implementing network segmentation to isolate routers and apply compensating controls. Security teams should prioritize developing detection rules for this specific attack vector and monitor for any exploit attempts in their environments.
Operational Relevance
For security professionals, this vulnerability highlights the importance of regular firmware updates for network devices and robust network segmentation strategies. Red teams can use this vulnerability to demonstrate router compromise scenarios, while blue teams should focus on detection and response capabilities.
Threat intelligence teams should monitor for exploit kits incorporating this vulnerability, as it may become a favored entry point for attackers targeting enterprise networks. System administrators need to assess their exposure and implement appropriate security measures to protect critical infrastructure components.
Conclusion
CVE-2025-2727 represents a serious threat to organizations using vulnerable H3C Magic NX30 Pro routers. The combination of public exploit availability and lack of vendor response creates a challenging security situation that requires immediate attention from affected organizations.
This discovery underscores the critical importance of maintaining updated firmware on network devices and implementing comprehensive monitoring of critical infrastructure components. Security teams should remain vigilant for signs of exploitation while working to implement appropriate mitigation strategies.
