Summary
JeecgBoot before 3.9.5 contains an SQL injection flaw in which the SqlInjectionUtil keyword blocklist can be bypassed by inserting newline characters into dictionary and online report SQL fragments (CWE-89). An authenticated remote attacker with low privileges can send newline-separated payloads to endpoints such as /sys/dict/getDictItems to run boolean or time-based blind injection. This allows extraction of database contents, including administrator password hashes from sys_user.
