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

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.

AI-suggested

First, restrict access to the router's web interface to trusted IP addresses or internal networks only, preventing remote access from untrusted sources. Disable remote management features if enabled. Enforce strong authentication policies for router access, including changing default credentials and using complex passwords. Monitor router logs for suspicious activity indicative of attempted XSS exploitation. Educate network administrators about the risk of interacting with manipulated SSID inputs and advise caution when configuring wireless settings. Consider deploying network segmentation to isolate the router management interface from critical systems. If possible, replace or upgrade to a router model with a vendor-supported firmware that addresses this vulnerability. Additionally, implement web application firewalls or intrusion detection systems that can detect and block XSS payloads targeting the router's interface.

Description

A security vulnerability has been detected in Cudy TR1200 1.16.3-20230804-164635. Impacted is an unknown function of the file /cgi-bin/luci/admin/network/wireless/config/ of the component Wireless Settings Page. Such manipulation of the argument SSID leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using the Cudy TR1200 router, this vulnerability presents a moderate risk. Exploitation could lead to unauthorized access to router management interfaces, enabling attackers to alter network configurations, intercept traffic, or pivot to internal systems. This is particularly concerning for small and medium enterprises or home office setups relying on this router model, as they may lack advanced network defenses. The impact on confidentiality is moderate due to potential credential theft or session hijacking. Integrity could be compromised if attackers modify router settings. Availability impact is low as the vulnerability does not directly cause denial of service. Given the public disclosure and no vendor patch, attackers could weaponize this vulnerability to target European networks, especially in sectors with less stringent IT security controls. The requirement for user interaction (e.g., an administrator accessing the wireless settings page) somewhat limits exploitation but does not eliminate risk, especially in environments where multiple administrators or users access the router interface.

Summary

CVE-2025-11134 is a cross-site scripting (XSS) vulnerability identified in the Cudy TR1200 wireless router, specifically version 1.16.3-20230804-164635. The vulnerability resides in the Wireless Settings Page component, within the file /cgi-bin/luci/admin/network/wireless/config/. The issue arises from improper sanitization of the SSID parameter, which can be manipulated remotely by an attacker to inject malicious scripts. This vulnerability does not require authentication (as indicated by the CVSS vector AV:N and PR:H, but PR:H means high privileges, so authentication is required), but user interaction is needed (UI:P). The vendor was notified but has not responded or issued a patch. Although the CVSS score is moderate at 4.8, the exploit has been publicly disclosed, increasing the risk of exploitation. The vulnerability could allow attackers to execute arbitrary scripts in the context of the router's web interface, potentially leading to session hijacking, credential theft, or further network compromise. The lack of vendor response and patch availability heightens the urgency for affected users to implement mitigations.
