AI Analysis
Technical Summary
This vulnerability affects Wavlink WL-NU516U1 version 260515. An attacker can remotely exploit the wlink_uci_set_value function in /cgi-bin/adm.cgi by manipulating the lan_ip argument to perform OS command injection. This allows execution of arbitrary commands on the device. The vendor was contacted early and responded professionally by releasing a fixed version quickly. The CVSS 4.0 base score is 5.3, indicating a medium severity with network attack vector, low complexity, no user interaction, and limited impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary OS commands on the affected device, potentially compromising device integrity and control. The vulnerability affects confidentiality, integrity, and availability to a limited extent as per the CVSS vector. Public exploit code availability increases the likelihood of attacks against unpatched devices.
Mitigation Recommendations
A fixed version of the affected product has been released by the vendor. Users should upgrade to the fixed version immediately to remediate this vulnerability. Since the vendor has provided an official fix, applying the update is the recommended mitigation.
