Overview
CVE-2025-64444 details a critical OS Command Injection vulnerability affecting NCP-HG100 routers, specifically versions 1.4.48.16 and earlier. Successful exploitation of this vulnerability allows a remote attacker, with valid authentication credentials to the router’s management interface, to execute arbitrary operating system commands with root privileges. This represents a significant security risk, potentially allowing complete control over the affected device.
Technical Details
The vulnerability stems from improper neutralization of special elements within user-supplied input that is subsequently used in an OS command. This means that malicious code can be injected into a legitimate command, allowing the attacker to execute commands of their choosing with the elevated privileges of the operating system. The specific vulnerable parameter or functionality is not explicitly detailed in the provided information but can be inferred to be within the web management interface accessible after authentication.
CVSS Analysis
The provided information indicates that the CVSS score is currently N/A (Not Available). This might be because the vulnerability is newly discovered, or the analysis is still in progress. However, given the ability to execute commands as root, it is likely that once a CVSS score is assigned, it will be rated as Critical (CVSS score of 9.0-10.0).
Possible Impact
The impact of successfully exploiting CVE-2025-64444 is severe. An attacker could:
- Gain complete control of the compromised router.
- Modify router configuration, potentially redirecting traffic to malicious servers.
- Install malware on the router, turning it into a botnet node.
- Steal sensitive information from the network connected to the router.
- Deny service to legitimate users by disrupting network connectivity.
Mitigation and Patch Steps
The primary mitigation step is to upgrade to a patched firmware version provided by the vendor, if available. Refer to the vendor’s security advisory for specific instructions and to download the updated firmware. As per the provided reference links, you should check the following:
- Apply the Patch: Check Sony Network Communication Inc support page for the latest firmware updates and instructions specific to the NCP-HG100.
- Monitor Security Advisories: Regularly check the vendor’s website and security advisories for further updates and mitigation guidance.
- Disable Remote Management (If Possible): If not essential, disable remote access to the router’s management interface to reduce the attack surface.
- Implement Strong Passwords: Ensure that a strong and unique password is set for the router’s management interface.
