Description The issue allows local attackers to execute arbitrary code via the get system log and get crash log functions of the logread module, as well as the upgrade online function of the upgrade module. This is due to the lack of measures to neutralize special elements used in the operating system command. Exploitation of the issue may allow an attacker to execute arbitrary code. Approximately 36,128 devices are potentially affected, mainly distributed in the United States, China, and other countries.
