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

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 2026-10-25.

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.

2) Enforce strong authentication mechanisms and regularly update credentials to reduce the risk of privilege escalation. 3) Monitor router logs and network traffic for unusual commands or access patterns indicative of exploitation attempts. 4) Disable or restrict remote management interfaces if not strictly necessary. 5) Consider deploying network intrusion detection/prevention systems (IDS/IPS) with signatures targeting known exploits of this vulnerability. 6) Plan for replacement or firmware upgrade to a secure version once available from the vendor or consider alternative hardware with active vendor support. 7) Educate network administrators about the vulnerability and ensure incident response plans include steps for compromised network devices. These targeted actions go beyond generic advice by focusing on access control, monitoring, and proactive network defense tailored to this vulnerability's characteristics.

Description

A flaw has been found in Edimax BR-6478AC V3 1.0.15. The affected element is the function sub_44CCE4 of the file /boafrm/formSysCmd. This manipulation of the argument sysCmd causes os command injection. The attack may be initiated remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The primary impact of CVE-2025-14094 is the potential for remote attackers with high privileges to execute arbitrary OS commands on affected Edimax BR-6478AC V3 routers. This can lead to complete compromise of the device, including unauthorized configuration changes, installation of malware, or disruption of network traffic. Compromised routers can serve as entry points for lateral movement within an organization's internal network, risking broader infrastructure compromise. The vulnerability affects confidentiality, integrity, and availability: attackers can exfiltrate sensitive data, alter device configurations, or cause denial of service. Although exploitation requires high privileges, the availability of a public exploit increases the risk that attackers may combine this with other vulnerabilities or credential theft to escalate privileges. Organizations relying on this router model for critical network infrastructure may face significant operational and security risks if unmitigated.

Summary

CVE-2025-14094 is an OS command injection vulnerability affecting the Edimax BR-6478AC V3 router firmware version 1.0.15. The vulnerability resides in the function sub_44CCE4 located in the /boafrm/formSysCmd file. This function improperly sanitizes or validates the sysCmd argument, enabling an attacker to inject arbitrary operating system commands. The attack vector is remote network access, and exploitation does not require user interaction; however, it requires the attacker to have high privileges on the device, which may mean prior authentication or elevated access. The vulnerability has a CVSS 4.0 base score of 5.1, reflecting medium severity due to the requirement of high privileges and limited scope of impact. An exploit has been publicly disclosed, increasing the risk of future exploitation. This vulnerability could allow attackers to execute arbitrary commands on the device, potentially leading to full device compromise, disruption of network services, or pivoting attacks within the internal network. The lack of vendor response and patch availability increases the urgency for organizations to implement compensating controls.
