Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Monitor Sony's official channels for firmware updates addressing CVE-2025-64444 and apply patches immediately upon release.
Restrict access to the management interface by implementing network segmentation and firewall rules to allow only trusted IP addresses or VPN connections.
Enforce strong authentication policies, including complex passwords and multi-factor authentication where possible, to reduce the risk of credential compromise.
Regularly audit device access logs to detect unauthorized login attempts or suspicious activities.
Consider disabling remote management interfaces if not required or replacing affected devices with models not vulnerable to this issue.
Employ intrusion detection systems capable of recognizing anomalous command execution patterns on network devices.
Educate administrators on the risks of OS command injection and the importance of secure credential management.
If immediate patching is not possible, implement compensating controls such as network-level access restrictions and enhanced monitoring.

Description

Improper neutralization of special elements used in an OS command ('OS Command Injection') issue exists in NCP-HG100 1.4.48.16 and earlier. If exploited, a remote attacker who has obtained the authentication information to log in to the management page of the product may execute an arbitrary OS command with root privileges.

Impact

For European organizations, this vulnerability poses a significant risk to network security, especially for those deploying Sony NCP-HG100 Cellular models in critical communications infrastructure. Successful exploitation could lead to full device compromise, enabling attackers to intercept or manipulate sensitive communications, disrupt network availability, or use the device as a pivot point for further attacks within the corporate network. Confidentiality is at risk due to potential data leakage, integrity is compromised through unauthorized command execution, and availability may be affected by malicious disruption or device bricking. Given the root-level access gained, attackers could also install persistent backdoors or malware. The requirement for valid authentication reduces the risk somewhat but does not eliminate it, as credential theft or weak password policies could facilitate exploitation. This threat is particularly concerning for telecom providers, government agencies, and enterprises relying on these devices for secure cellular connectivity.
