Vulnerability details
The vulnerability allows a remote user to execute arbitrary code.
The vulnerability exists due to insecure deserialization in the Quartz JDBC job store when deserializing job data from the qrtz_job_details table. A remote user can inject a crafted serialized JobDataMap blob via SQL injection to execute arbitrary code.
Exploitation requires chaining with a SQL injection that can modify the JOB_DATA column, and the payload is triggered when the scheduled Datasource/check_status Quartz job runs.
