The vulnerability identified as CVE-2025-56009 is a Cross Site Request Forgery (CSRF) vulnerability present in KeeneticOS versions prior to 4.3. This vulnerability allows attackers to take over devices by adding additional users with full permissions, requiring the victim to open a malicious page. The CVSS score for this vulnerability is 5.3, categorizing it as medium severity.
Organizations using Keenetic products should be aware of the risk this vulnerability poses. Attackers may leverage this CSRF vulnerability to compromise user accounts and potentially gain further access to sensitive device management functionalities. The urgency for defenders is classified as medium, and they should prioritize patching this vulnerability in their systems.
Currently, there is no known public exploit or proof of concept for CVE-2025-56009, which indicates a lack of immediate threat for widespread exploitation. However, organizations should not dismiss the importance of remediation. The potential impact on operations and reputation can be significant if left unaddressed.
Organizations should prioritize patching immediately to ensure devices are secured against this vulnerability. Regular monitoring and updates to security policies are essential in maintaining a robust defense against such vulnerabilities.
Vulnerability Details
CVE-2025-56009 is classified as a Cross Site Request Forgery (CSRF) vulnerability affecting KeeneticOS prior to version 4.3. The vulnerability is characterized by its ability to allow unauthorized actions on a device through the exploitation of session management. The CWE classification associated with this vulnerability is CWE-352.
The vulnerability is officially scored with a CVSS 3.1 base score of 5.3. The attack vector is categorized as network, with low attack complexity, and does not require any privileges or user interaction. The confidentiality impact is rated as low, while integrity and availability impacts are rated as none.
Keenetic, the vendor of the affected product, advises all users to upgrade to version 4.3 or later to mitigate the risks posed by this vulnerability. The vulnerability was published on October 23, 2025.
Technical Analysis
The root cause of CVE-2025-56009 lies in improper validation of requests to the "/rci" API endpoint. This flaw allows attackers to exploit the vulnerability by tricking users into making requests that perform unauthorized actions by leveraging their authentication session.
The attack vector is network-based, meaning that an attacker can initiate the attack remotely without needing physical access to the device. The attack complexity is low, allowing even less sophisticated attackers to exploit this vulnerability successfully. Importantly, no privileges are required to exploit this issue, and no user interaction is necessary.
From a security impact perspective, the confidentiality impact is low, as the attacker does not gain access to sensitive data. However, the ability to add users with full permissions can lead to unauthorized access and control over the device, which poses a significant security risk.
Risk & Impact Analysis
Risk to organizations includes unauthorized user management, which can lead to compromised device integrity and potential data exposure. This vulnerability can be particularly concerning for organizations relying on Keenetic devices for critical infrastructure. The blast radius potential is significant, as successful exploitation may allow attackers to escalate privileges further, gaining unauthorized access to sensitive configurations.
Organizations should assess their deployment of Keenetic devices and prioritize remediation based on the CVSS score of 5.3. The urgency for patching is classified as medium, indicating that while immediate action may not be necessary, it should be scheduled as part of the next patch cycle.
Given the low EPSS score of 0.000230000, the probability of exploitation in the wild appears minimal at this time. Nevertheless, organizations should remain vigilant and monitor for any developments regarding this vulnerability.
