A security vulnerability has been detected in Wavlink WL-WN570HA1 firmware version R70HA1 V1410_221110. This vulnerability allows command injection through manipulation of the argument command in the function set_sys_cmd located in the file /cgi-bin/adm.cgi. The impact is significant as it is possible to launch the attack remotely. The exploit has been disclosed publicly and may be utilized by attackers. Notably, the vendor has acted professionally by confirming that the vulnerable firmware version has been removed from their website.
Risk to organizations includes exposure to command injection attacks, potentially leading to unauthorized command execution. The vulnerability has a CVSS score of 2.1, categorized as low severity. Despite the low score, organizations should not underestimate the risk associated with this vulnerability, especially if they are using unsupported firmware versions.
Given that this vulnerability affects products that are no longer supported by the maintainer, organizations utilizing these devices should prioritize remediation steps. Organizations should address this vulnerability in their security practices to minimize potential exploitation risks.
Organizations should prioritize patching immediately.
Vulnerability Details
The official CVE description states that a security vulnerability has been detected in Wavlink WL-WN570HA1 firmware version R70HA1 V1410_221110. The vulnerability is identified by CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) and CWE-77 (Improper Neutralization of Special Elements Used in a Command ('Command Injection')).
The CVSS score is 2.1, indicating a low severity level. The vulnerability is classified as having a low attack complexity, requiring low privileges, and no user interaction is needed. The publication date of the vulnerability is May 3, 2026.
Technical Analysis
The root cause of this vulnerability is a lack of proper input validation in the command handling function, allowing attackers to inject arbitrary commands that the system may execute. The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely. The attack complexity is low, as no special conditions are required for exploitation.
In terms of privileges, attackers may require low-level access to exploit this vulnerability, which increases the risk of exploitation in environments where devices are inadequately secured. User interaction is not required, enhancing the ease of attack.
The vulnerability impacts confidentiality, integrity, and availability, all rated low, indicating that while the potential for damage exists, it is relatively limited compared to higher severity vulnerabilities.
Risk & Impact Analysis
Real-world deployment risk associated with this vulnerability escalates due to its remote exploitation potential. Organizations utilizing the affected firmware may face unauthorized command execution, leading to potential data breaches or system compromise. The blast radius can be significant if the vulnerable devices are integrated into larger networks, allowing attackers to pivot to more critical systems.
Organizations should assess their exposure to this vulnerability critically, especially if they rely on unsupported devices. The urgency assessment based on the provided CVSS score suggests that organizations should schedule remediation as part of their security practices.
