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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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

Disclosed: evidence found.
CVE published 24 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

Immediate mitigation should focus on restricting access to the router’s management interface, ensuring it is not exposed to untrusted networks or the internet.
Enforce strong authentication mechanisms and regularly update credentials to reduce risk of unauthorized access.
Monitor router logs and network traffic for unusual activities indicative of exploitation attempts, such as unexpected command execution or configuration changes.
Segment networks to limit the impact of a compromised router, isolating critical systems from devices with known vulnerabilities.
Engage with ELECOM CO.,LTD. for firmware updates or patches addressing this vulnerability; if unavailable, consider temporary replacement or additional protective controls such as web application firewalls or intrusion prevention systems that can detect and block command injection patterns.
Educate network administrators on the risks of OS command injection and the importance of secure configuration and monitoring.
Implement multi-factor authentication for router access where supported to further reduce risk of credential compromise.

Description

WRC-X3000GS, WRC-X3000GSA, and WRC-X3000GSN contain an improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in Connection Diagnostics page. If a remote authenticated attacker sends a specially crafted request to the affected product, an arbitrary OS command may be executed.

Impact

For European organizations, exploitation of this vulnerability could have severe consequences. The WRC-X3000GS series routers are used in both consumer and small-to-medium business environments, and potentially in some enterprise settings. Successful exploitation could allow attackers to gain control over network infrastructure, leading to interception or manipulation of sensitive communications, disruption of internet connectivity, and potential lateral movement within corporate networks. This could compromise confidentiality of personal and corporate data, integrity of network operations, and availability of critical services. Given the router’s role as a gateway device, attackers could establish persistent footholds or launch further attacks against connected systems. The requirement for authentication limits exposure but does not eliminate risk, as credential theft or insider threats could facilitate exploitation. The impact is heightened in sectors with stringent data protection requirements under GDPR and critical infrastructure entities, where network compromise could lead to regulatory penalties and operational disruptions.
