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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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 2026-10-26.

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.

What to do

No fix will be released: Edimax BR-6208AC is end of life. Replace it, or isolate it from untrusted networks until you can.

AI-suggested

Given the Edimax BR-6208AC V2 is end-of-life with no forthcoming patches, the primary mitigation is to replace all affected devices with newer, supported models that receive regular security updates. Until replacement, organizations should isolate these routers from untrusted networks by placing them behind additional firewalls or network segmentation to limit exposure. Disable remote management interfaces if possible to reduce attack surface. Monitor network traffic for unusual activity indicative of exploitation attempts, such as unexpected command execution or configuration changes. Employ network intrusion detection systems (NIDS) with signatures targeting known exploit patterns for this vulnerability. Regularly audit device firmware versions and configurations to identify any remaining vulnerable units. Educate network administrators about the risks and signs of compromise related to this vulnerability. Avoid exposing the web-based configuration interface to the internet or untrusted networks. If replacement is delayed, consider deploying compensating controls like VPNs for management access and strict access control lists (ACLs).

Description

A vulnerability was identified in Edimax BR-6208AC 1.02/1.03. Affected is the function formStaDrvSetup of the file /goform/formStaDrvSetup of the component Web-based Configuration Interface. The manipulation of the argument rootAPmac leads to command injection. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. Edimax confirms this issue: "The product mentioned, EDIMAX BR-6208AC V2, has reached its End of Life (EOL) status. It is no longer supported or maintained by Edimax, and it is no longer available for purchase in the market. Consequently, there will be no further firmware updates or patches for this device. We recommend users upgrade to newer models for better security." This vulnerability only affects products that are no longer supported by the maintainer.

Impact

The impact of CVE-2025-15256 is significant for organizations still using the Edimax BR-6208AC routers running vulnerable firmware. Successful exploitation allows remote attackers to execute arbitrary commands with elevated privileges, potentially leading to full device compromise. This can result in unauthorized access to internal networks, interception or manipulation of network traffic, disruption of network services, and use of the device as a foothold for further attacks. Since the device is end-of-life and unsupported, organizations cannot rely on vendor patches, increasing the risk of persistent exploitation. The vulnerability threatens confidentiality by exposing sensitive network configurations, integrity by allowing unauthorized changes, and availability by enabling denial-of-service conditions. Enterprises with critical infrastructure or sensitive data behind these routers face heightened risks of data breaches, operational disruption, and reputational damage. The medium CVSS score reflects the balance between ease of exploitation and the limited scope to a specific device model and firmware versions.

Summary

CVE-2025-15256 is a remote command injection vulnerability found in Edimax BR-6208AC router firmware versions 1.02 and 1.03. The flaw exists in the web-based configuration interface, specifically in the formStaDrvSetup function within the /goform/formStaDrvSetup endpoint. An attacker can manipulate the rootAPmac parameter to inject arbitrary system commands, which the device executes with elevated privileges. This vulnerability requires no authentication or user interaction, making it remotely exploitable over the network. The Edimax BR-6208AC V2 model affected by this vulnerability has reached its end-of-life status, meaning no security patches or firmware updates will be released to address this issue. Although no known exploits are currently observed in the wild, a public exploit is available, increasing the risk of exploitation. The vulnerability impacts the confidentiality, integrity, and availability of the device and any network it protects, as attackers could execute arbitrary commands, potentially leading to device takeover, network pivoting, or denial of service. The CVSS 4.0 vector indicates low attack complexity, no privileges or user interaction required, and partial impact on confidentiality, integrity, and availability. Given the lack of vendor support, mitigation options are limited to device replacement or network segmentation.
