Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVE-2018-10987

High
7.5/10

Summary

An issue was discovered on Dongguan Diqee Diqee360 devices. The affected vacuum cleaner suffers from an authenticated remote code execution vulnerability. An authenticated attacker can send a specially crafted UDP packet, and execute commands on the vacuum cleaner as root. The bug is in the function REQUEST_SET_WIFIPASSWD (UDP command 153). A crafted UDP packet runs "/mnt/skyeye/mode_switch.sh %s" with an attacker controlling the %s variable. In some cases, authentication can be achieved with the default password of 888888 for the admin account.

CWE-78 - OS Command Injection

The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
