Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2026-24105 is a command injection vulnerability found in the Tenda AC15 router firmware version V15.03.05.18_multi, specifically in the goform/formsetUsbUnload component.'}, {'type': 'paragraph', 'content': 'The issue occurs because the input parameter "v1" is not properly validated before being passed to the function doSystemCmd. This lack of validation allows an attacker to inject arbitrary system commands.'}, {'type': 'paragraph', 'content': 'An example proof-of-concept shows that by sending a specially crafted POST request to the endpoint "/goform/setUsbUnload" with a parameter containing a command injection string (such as ";ls"), the attacker can cause the router to execute unintended commands.'}] [1]

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary system commands on the affected Tenda AC15 router.

Such unauthorized command execution could lead to full compromise of the device, enabling the attacker to manipulate router settings, intercept or redirect network traffic, or use the device as a foothold for further attacks within the network.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by sending a specially crafted POST request to the endpoint "/goform/setUsbUnload" on the Tenda AC15 router. The request should include the parameter "deviceName" with a payload containing a command injection string, such as ";ls".'}, {'type': 'paragraph', 'content': "For example, using a Python script with the requests library, you can send a POST request to the target device's IP address (e.g., 192.168.84.101) to test if the device executes the injected command."}, {'type': 'list_item', 'content': 'Send a POST request to http://<target-ip>/goform/setUsbUnload with deviceName set to a command injection payload like ";ls".'}, {'type': 'list_item', 'content': 'Observe if the injected command executes, indicating the presence of the vulnerability.'}] [1]
