Description

JeecgBoot before 3.9.5 contains an sql injection vulnerability that allows authenticated attackers to bypass the SqlInjectionUtil keyword blocklist by inserting newline characters into dictionary and online report SQL fragments. Attackers can send newline-separated payloads to endpoints like /sys/dict/getDictItems for boolean or time-based blind injection, extracting database contents including administrator password hashes from sys_user.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
