Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 5 Dec 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

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 2026-10-26.

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 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

To mitigate CVE-2025-14092, organizations should first verify if they are using the Edimax BR-6478AC V3 router with firmware version 1.0.15. Implement strong authentication controls and ensure administrative credentials are complex and changed regularly. Network segmentation should be employed to isolate the router from critical systems and reduce the impact of potential compromise. Monitoring network traffic and device logs for unusual activity related to the /boafrm/formDebugDiagnosticRun endpoint or unexpected command execution attempts is recommended. If possible, consider replacing affected devices with models from vendors that provide timely security updates. Additionally, organizations should maintain up-to-date inventories of network devices and apply security best practices for IoT and network infrastructure devices. Engage in threat intelligence sharing to stay informed about any emerging exploits targeting this vulnerability.

Description

A security vulnerability has been detected in Edimax BR-6478AC V3 1.0.15. This issue affects the function sub_416898 of the file /boafrm/formDebugDiagnosticRun. The manipulation of the argument host leads to os command injection. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The impact of CVE-2025-14092 is significant for organizations using the Edimax BR-6478AC V3 router with firmware version 1.0.15. Successful exploitation allows attackers to execute arbitrary OS commands remotely, potentially leading to full device compromise. This can result in unauthorized access to network traffic, manipulation or disruption of network services, and the introduction of persistent backdoors. The confidentiality of sensitive data passing through the router may be compromised, and the integrity of network configurations can be altered maliciously. Availability may also be affected if attackers disrupt router operations or cause denial of service. Given the router’s role as a network gateway, exploitation could serve as a foothold for lateral movement within an organization’s internal network. The requirement for high privileges reduces the likelihood of widespread exploitation but does not eliminate risk, especially in environments where administrative access is weakly protected or compromised. The absence of a vendor patch and the public disclosure increase the urgency for organizations to implement mitigations to prevent exploitation.
