| Titre | JEECG JeecgBoot v3.9.1 SQL Injection |
|---|
| Description | JEECG Boot contains an authenticated blind SQL injection vulnerability in /sys/dict/loadDict/{dictCode}. In the audited 3.9.1 source snapshot, the application concatenates the untrusted keyword parameter directly into a SQL LIKE condition inside SysDictServiceImpl.getFilterSql and renders the resulting filter through a MyBatis ${filterSql} fragment. The dictionary-specific blacklist does not block single quotes, boolean operators, or substring(), allowing a low-privileged authenticated user to infer sensitive non-whitelisted columns such as password and salt from sys_user. The issue is practically exploitable in default deployments because the request-signing secret is hardcoded in the codebase and configuration. |
