AI Analysis
Technical Summary
The Tenda AC1206 router firmware 15.03.06.23_multi_TD01 contains a stack-based buffer overflow vulnerability in the set_device_name function within the /goform/SetOnlineDevName HTTP management interface. This vulnerability arises from improper handling of the devName argument, allowing remote attackers to overflow the stack and potentially execute arbitrary code or cause denial of service. The vulnerability is tracked as CVE-2026-19788 and has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Public exploit code is available, increasing the risk of exploitation. No official patch or vendor advisory has been provided to date.
Potential Impact
Successful exploitation of this vulnerability can lead to full compromise of the affected device, including unauthorized disclosure of information, modification of device settings, and denial of service. The vulnerability affects confidentiality, integrity, and availability with high impact. The remote attack vector with low attack complexity and no user interaction required increases the risk.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the device's web management interface to trusted networks only and monitor for any suspicious activity related to the /goform/SetOnlineDevName endpoint. Avoid exposing the management interface to untrusted networks.
