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: 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 6 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.
CVSS exploit maturity: proof of concept public
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), 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-6288ACL 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-6288ACL and absence of patches, organizations should prioritize device replacement with supported models that receive regular security updates. If immediate replacement is not feasible, network segmentation should be implemented to isolate the vulnerable device from critical assets and limit exposure. Disable remote management interfaces or restrict access to trusted IP addresses only. Employ web filtering or intrusion detection systems to detect and block suspicious URLs or payloads targeting the manualssid parameter. Educate users about the risks of clicking unsolicited links, especially those related to router management interfaces. Regularly audit network devices to identify legacy or unsupported hardware and develop a phased decommissioning plan. Monitor vendor communications for the forthcoming consolidated security advisory and apply any recommended mitigations promptly. Consider deploying network-level protections such as DNS filtering or proxy solutions to reduce the risk of successful exploitation.

Description

A vulnerability has been found in Edimax BR-6288ACL up to 1.12. Impacted is the function wiz_WISP24gmanual of the file wiz_WISP24gmanual.asp. Such manipulation of the argument manualssid leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public 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 this vulnerability is on the confidentiality and integrity of the affected systems. Successful exploitation allows attackers to execute arbitrary scripts in the context of the router's web interface, potentially stealing session tokens, credentials, or performing unauthorized actions on behalf of the user. This can lead to unauthorized access to router configuration, network traffic interception, or pivoting to internal network resources. Since the device is often used in small office or home office environments, compromised routers could serve as entry points for broader network attacks. The lack of vendor support and patches increases the risk for organizations that continue to use these devices, as they remain exposed to emerging exploit techniques. The medium CVSS score reflects the moderate ease of exploitation and limited scope, but the impact on network security posture can be significant if exploited. The absence of known exploits in the wild currently limits immediate widespread impact, but the public disclosure may lead to increased targeting.
