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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within 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), CVSS vector, 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.

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 absence of official patches or firmware updates, mitigation must focus on reducing the attack surface and exposure. The primary recommendation is to immediately disable the FTP service on the Edimax BR-6208AC device, as advised by the vendor, since this service is the attack vector for the vulnerability. Disabling FTP will prevent remote exploitation of the path traversal flaw while allowing the device to continue functioning for other purposes. Network administrators should also isolate the device from untrusted networks, such as the internet, by placing it behind firewalls or restricting access to trusted internal networks only. Monitoring network traffic for unusual FTP requests or scanning activity targeting the device can help detect attempted exploitation. Ultimately, organizations should plan to replace the BR-6208AC with a modern, supported router model that receives regular security updates. For environments where replacement is not immediately feasible, implementing compensating controls such as network segmentation and strict access controls is critical. Regularly auditing network devices for unsupported hardware can prevent prolonged exposure to similar legacy vulnerabilities.

Description

A vulnerability was detected in Edimax BR-6208AC 1.02. This impacts the function handle_retr of the component FTP Daemon Service. The manipulation results in path traversal. The attack may be launched remotely. The exploit is now public and may be used. Edimax confirms this issue: "This product is no longer available in the market and has been discontinued for five years. Consequently, Edimax no longer provides technical support, firmware updates, or security patches for this specific model. However, to ensure the safety of our remaining active users, we acknowledge this report and will take the following mitigation actions: (A) We will issue an official security advisory on our support website. (B) We will strongly advise users to disable the FTP service on this device to mitigate the reported risk, by which the product will still work for common use. (C) We will recommend users upgrade to newer, supported models." This vulnerability only affects products that are no longer supported by the maintainer.

Impact

The primary impact of this vulnerability is unauthorized disclosure of sensitive information due to path traversal, which can expose configuration files, credentials, or other sensitive data stored on or accessible through the device. Organizations using the Edimax BR-6208AC in their networks may face confidentiality breaches, potentially leading to further compromise if attackers obtain credentials or configuration details. Although the vulnerability does not directly affect device integrity or availability, the exposure of sensitive files can facilitate subsequent attacks. Since the device is discontinued and unsupported, organizations cannot rely on vendor patches, increasing the risk of exploitation over time. The ease of remote exploitation without authentication means attackers can scan for vulnerable devices and attempt exploitation opportunistically. This risk is particularly relevant for environments where these routers remain in use, such as small offices or home networks that have not upgraded hardware. The lack of active exploit reports suggests limited current impact, but public exploit availability raises the likelihood of future attacks. Overall, the vulnerability poses a moderate risk to confidentiality and network security posture for affected users.

Summary

CVE-2025-14910 is a medium-severity path traversal vulnerability affecting the Edimax BR-6208AC router running firmware version 1.02. The vulnerability resides in the FTP Daemon Service's handle_retr function, which improperly sanitizes file path inputs. This allows a remote attacker to craft malicious FTP commands that traverse directories and access files outside the intended FTP root directory. The flaw can be exploited remotely without authentication or user interaction, requiring only low attack complexity. The vulnerability impacts confidentiality by potentially exposing sensitive files stored on the device or accessible through its filesystem. Edimax has confirmed the issue but no longer supports this product, which has been discontinued for over five years. No official patches or firmware updates are available. The vendor advises users to disable the FTP service to mitigate risk and upgrade to supported devices. Although no active exploitation has been reported, public exploit code exists, increasing the risk of opportunistic attacks. The CVSS 4.0 vector indicates no privileges or user interaction are needed, with partial confidentiality impact and no integrity or availability impact. This vulnerability highlights the risks of using unsupported legacy network devices with exposed services.
