Apache kylin checks the legitimacy of the project before executing some commands with the project name passed in by the user.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 88.9%, higher than 100% of all known CVEs. Patch or mitigate before the next change window.
Description
Apache kylin checks the legitimacy of the project before executing some commands with the project name passed in by the user. There is a mismatch between what is being checked and what is being used as the shell command argument in DiagnosisService. This may cause an illegal project name to pass the check and perform the following steps, resulting in a command injection vulnerability. This issue affects Apache Kylin 4.0.0.
