Description
Version of the vulnerability
<=0.1.0
In CalculateAlarm.java, AviatorEvaluator is used to directly execute expression functionality without any configured security policies, leading to potential AviatorScript injection vulnerabilities (which by default can execute arbitrary static methods).
Description of the vulnerability.
For example, running the following AviatorScript script can lead to executing a command that pops up the calculator on Linux.
