Assigner: VulDB

Description
A flaw has been found in Tenda AX1803 1.0.0.1. The affected element is the function fromGetWifiGuestBasic of the file /goform/WifiGuestSet. Executing a manipulation of the argument guestWrlPwd/guestEn/guestSsid/hideSsid/guestSecurity can lead to stack-based buffer overflow. The attack may be launched remotely. The exploit has been published and may be used.

CWE ID Description
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
CWE-121 A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

Executive Summary

CVE-2026-1329 is a critical stack-based buffer overflow vulnerability in the Tenda AX1803 router firmware version 1.0.0.1. It occurs in the function fromGetWifiGuestBasic within the /goform/WifiGuestSet endpoint. The vulnerability arises because several parameters (guestWrlPwd, guestEn, guestSsid, hideSsid, guestSecurity) received via HTTP POST requests are stored and retrieved without proper length validation, leading to a stack-based buffer overflow. This flaw allows remote attackers to cause memory corruption and potentially execute arbitrary code on the device without authentication. A proof-of-concept exploit is publicly available, making this vulnerability highly dangerous. [1, 2, 3, 4, 5, 6]

Impact Analysis

This vulnerability can severely impact you by allowing remote attackers to execute arbitrary code on your Tenda AX1803 router, potentially taking full control of the device. It can compromise the confidentiality, integrity, and availability of the router, leading to unauthorized access, disruption of network services, and possible further attacks on connected devices. Since the exploit requires no authentication and is publicly available, the risk of exploitation is high. There are currently no known mitigations, so replacing the affected device is recommended to avoid risk. [1, 2, 3, 4, 5, 6]

Detection Guidance

This vulnerability can be detected by monitoring HTTP POST requests to the /goform/WifiGuestSet endpoint on the Tenda AX1803 router, specifically looking for unusually long or malformed values in the parameters guestWrlPwd, guestEn, guestSsid, hideSsid, and guestSecurity. Since the vulnerability arises from stack-based buffer overflow due to lack of length validation on these parameters, detection can involve capturing and analyzing HTTP traffic for suspicious payloads targeting these parameters. However, no specific detection commands or tools are provided in the available resources. [1, 2, 3, 4, 5, 6]

Mitigation Strategies

Immediate mitigation steps include replacing the affected Tenda AX1803 router firmware version 1.0.0.1 with a patched or updated version if available. Since no known countermeasures or mitigations currently exist, it is recommended to avoid using the vulnerable device or disable the WiFi guest settings interface if possible. Additionally, restricting remote access to the router's management interface and monitoring for exploit attempts can help reduce risk until a fix is applied. [1]
