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 18 Aug 2025
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

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 2026-10-25.

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.

AI-suggested

Given the absence of an official patch from Netis, European organizations should implement the following specific mitigations: 1) Immediately restrict access to the router's web management interface by disabling remote management or limiting it to trusted IP addresses via firewall rules. 2) Change default credentials to strong, unique passwords to prevent unauthorized access. 3) If possible, disable the wireless settings page or any features that allow SSID modification via the web interface to reduce attack surface. 4) Monitor network traffic for suspicious requests targeting the router's interface, particularly those containing suspicious payloads in the SSID parameter. 5) Consider deploying network segmentation to isolate vulnerable routers from critical systems and sensitive data. 6) Replace affected Netis WF2419 devices with alternative routers from vendors with active security support, especially in environments where patching is not feasible. 7) Educate users and administrators about the risks of XSS and the importance of not interacting with suspicious router management pages or links. 8) Employ web application firewalls (WAFs) or intrusion prevention systems (IPS) that can detect and block XSS attack patterns targeting the router's interface.

Description

A vulnerability was determined in Netis WF2419 1.2.29433. This vulnerability affects unknown code of the file /index.htm of the component Wireless Settings Page. This manipulation of the argument SSID with the input <img/src/onerror=prompt(8)> causes cross site scripting. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, this vulnerability poses a moderate risk, particularly for those using Netis WF2419 routers in their network infrastructure. Successful exploitation could lead to unauthorized access to router management interfaces, enabling attackers to alter network configurations, redirect traffic, or intercept sensitive communications. This could compromise confidentiality and integrity of internal communications and potentially disrupt availability if network settings are manipulated. Organizations with remote management enabled or exposed router interfaces are at higher risk. Additionally, since the vulnerability requires no authentication and can be triggered remotely, attackers could exploit it over the internet if the router's management interface is accessible externally. This risk is heightened in small and medium enterprises or home office environments where such devices are common and security controls may be limited. The public disclosure of the exploit code increases the likelihood of opportunistic attacks targeting vulnerable devices in Europe. The impact could extend to critical infrastructure sectors if these routers are deployed in operational environments without adequate segmentation or monitoring.
