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).

Impact Analysis

The vulnerability can be exploited remotely to compromise the affected Tenda O3 router, potentially allowing attackers to execute arbitrary code, disrupt device operation causing denial of service, and impact the confidentiality, integrity, and availability of the device. This could lead to unauthorized control over the router and network disruptions. [2, 3]

Executive Summary

This vulnerability is a stack-based buffer overflow in the Tenda O3 router firmware version 1.0.0.10(2478). It occurs in the SetValue/GetValue functions of the /goform/setVlanConfig endpoint when the 'lan' argument is manipulated with crafted input. This improper input handling allows an attacker to overflow the stack buffer remotely, potentially leading to arbitrary code execution or denial of service. [2, 3]

Detection Guidance

This vulnerability can be detected by monitoring or testing the /goform/setVlanConfig endpoint for abnormal or malicious POST requests manipulating the 'lan' parameter. Since a public proof-of-concept exploit is available on GitHub, you can use crafted HTTP POST requests targeting this endpoint to check if the device is vulnerable. Specific commands would involve using tools like curl or specialized vulnerability scanners to send payloads to /goform/setVlanConfig and observe the response or device behavior. However, no explicit detection commands are provided in the available resources. [2, 3]

Mitigation Strategies

No known mitigations or countermeasures have been identified for this vulnerability. It is recommended to consider replacing the affected product (Tenda O3 router version 1.0.0.10(2478)) to avoid exploitation. Additionally, restricting remote access to the device and monitoring network traffic for suspicious activity targeting the /goform/setVlanConfig endpoint may help reduce risk until a patch or fix is available.
