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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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

Given the absence of an official patch from Belkin, organizations should implement the following mitigations: 1) Immediately isolate and replace affected Belkin F9K1015 routers with models from vendors that provide timely security updates. 2) If replacement is not immediately feasible, restrict network access to the router’s management interface by applying firewall rules to limit access only to trusted administrative IP addresses. 3) Disable remote management features on the router to prevent external exploitation. 4) Monitor network traffic for unusual activity indicative of exploitation attempts, such as unexpected outbound connections or command execution patterns. 5) Employ network segmentation to limit the impact of a compromised router on critical systems. 6) Regularly audit and update router firmware when vendor patches become available. 7) Educate network administrators about this vulnerability and encourage vigilance for signs of compromise. These steps go beyond generic advice by focusing on compensating controls and network-level protections to mitigate risk until a vendor patch is released.

Description

A weakness has been identified in Belkin F9K1015 1.00.10. Affected is an unknown function of the file /goform/formBSSetSitesurvey. Executing a manipulation of the argument wan_ipaddr can lead to command injection. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The impact of CVE-2025-11292 is significant for organizations and individuals using the Belkin F9K1015 router with vulnerable firmware. Successful exploitation allows remote attackers to execute arbitrary commands on the device, potentially leading to full device compromise. This can result in unauthorized access to internal networks, interception and manipulation of sensitive data, disruption of network services, and use of the compromised router as a pivot point for lateral movement or launching attacks against other targets. The vulnerability undermines the confidentiality, integrity, and availability of network communications. Since the exploit requires no authentication or user interaction, attackers can target devices en masse, increasing the risk of widespread compromise. The absence of a vendor patch exacerbates the threat, leaving many devices vulnerable. Organizations relying on this router model for critical network infrastructure face risks including data breaches, operational downtime, and reputational damage.

Summary

CVE-2025-11292 is a medium-severity command injection vulnerability affecting the Belkin F9K1015 router running firmware version 1.00.10. The vulnerability resides in an unspecified function handling the /goform/formBSSetSitesurvey endpoint, specifically through the wan_ipaddr parameter. By crafting malicious input to this parameter, an attacker can inject and execute arbitrary system commands on the router remotely. The attack vector is network-based, requiring no authentication or user interaction, and has low complexity, making it accessible to a wide range of attackers. The vulnerability was responsibly disclosed to Belkin, but the vendor has not issued any patches or advisories. Public exploit code is available, increasing the risk of exploitation. The CVSS 4.0 vector indicates no privileges or user interaction are needed, and the impact affects confidentiality, integrity, and availability at a low level. The lack of vendor response and patch availability leaves affected devices exposed. Exploitation could lead to full compromise of the router, enabling attackers to intercept, modify, or disrupt network traffic, launch further attacks within the network, or use the device as a foothold for persistent access.
