Vulnerability details
The vulnerability allows a remote user to execute arbitrary commands and write arbitrary files.
The vulnerability exists due to improper neutralization of special elements in the on-alert action command path when processing configuration-defined alert actions. A remote user can place shell operators in an alert action command in the configuration file to execute arbitrary commands and write arbitrary files.
