CVE-2026-2180
Published: 08 February 2026
Description
A vulnerability was identified in Tenda RX3 16.03.13.11. Affected is an unknown function of the file /goform/fast_setting_wifi_set. Such manipulation of the argument ssid_5g leads to stack-based buffer overflow. The attack can be launched remotely. The exploit is publicly available and…

Mitigating Controls (NIST 800-53 r5)AI
Directly prevents stack buffer overflows by enforcing input validation on parameters like ssid_5g at web endpoints such as /goform/fast_setting_wifi_set.
Mitigates exploitation of stack-based buffer overflows through memory protections like stack canaries and address space layout randomization.
Requires timely patching and remediation of the specific buffer overflow flaw in Tenda RX3 firmware version 16.03.13.11.
Security SummaryAI
CVE-2026-2180 is a stack-based buffer overflow vulnerability in Tenda RX3 firmware version 16.03.13.11. The flaw affects an unknown function in the /goform/fast_setting_wifi_set file, triggered by manipulation of the ssid_5g argument. It is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow), with 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).
The vulnerability enables remote exploitation by attackers with low privileges, such as authenticated users, requiring low complexity and no user interaction. Successful attacks can result in high impacts to confidentiality, integrity, and availability, potentially leading to arbitrary code execution on the device. A public exploit is available, which may facilitate its use in the wild.
Advisories and additional details are provided by VulDB (ctiid.344883, id.344883, submit.749703) and a GitHub issue at LX-66-LX/cve-new/issues/4, along with the vendor site at tenda.com.cn. Security practitioners should review these references for any patch availability or mitigation guidance.
