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: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within 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: 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

Exploitation evidence

Disclosed: evidence found.
CVE published 5 Feb 2026
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 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-6258n is end of life. Replace it, or isolate it from untrusted networks until you can.

AI-suggested

Given the end-of-life status of the Edimax BR-6258n and absence of patches, the most effective mitigation is to replace the affected routers with supported models that receive regular security updates. If immediate replacement is not feasible, organizations should implement network segmentation to isolate these devices from critical systems and restrict access to their management interfaces to trusted networks only. Deploying web filtering and intrusion prevention systems can help detect and block malicious URLs and redirect attempts. Administrators should disable remote management features if enabled and enforce strong access controls. Educating users about the risks of clicking suspicious links and verifying URLs can reduce the likelihood of successful exploitation. Monitoring network traffic for unusual redirect patterns or external connections originating from router management interfaces can provide early detection of exploitation attempts. Finally, organizations should maintain an inventory of legacy devices and prioritize their upgrade or decommissioning to reduce attack surface.

Description

A flaw has been found in Edimax BR-6258n up to 1.18. This issue affects the function formStaDrvSetup of the file /goform/formStaDrvSetup. This manipulation of the argument submit-url causes open redirect. The attack can be initiated remotely. The exploit has been published and may be used. The vendor confirms that the affected product is end-of-life. They confirm that they "will issue a consolidated Security Advisory on our official support website." This vulnerability only affects products that are no longer supported by the maintainer.

Impact

The primary impact of CVE-2026-1970 is the facilitation of phishing and social engineering attacks through open redirect abuse. Attackers can lure users into clicking URLs that appear legitimate but redirect to malicious websites hosting malware, credential harvesting pages, or other scams. This can lead to compromised user credentials, malware infections, or further network compromise. Although the vulnerability does not directly allow code execution or denial of service, it undermines user trust in the affected device’s web interface and can be a stepping stone for more complex attacks. Organizations relying on Edimax BR-6258n routers may face increased risk of targeted phishing campaigns, especially if these devices are accessible from untrusted networks. The lack of vendor support and patches exacerbates the risk, as vulnerable devices remain exposed. Additionally, the presence of such vulnerabilities in network infrastructure devices can affect overall network security posture and compliance with security standards.
