In Splunk Enterprise versions lower than 8.2.12, 9.0.6, and 9.1.1, an attacker can execute a specially crafted query that they can then use to serialize untrusted data. The attacker can use the query to execute arbitrary code.
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
