Summary

JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to create validation rules through the SysCheckRuleController importExcel handler. Attackers can upload a crafted Excel workbook to bypass the system:checkRule:add permission and bulk-create system-wide encoding validation rules with arbitrary regular expression patterns.

Risk Assessment

An attacker can inject malicious validation rules that may disrupt data processing or introduce vulnerabilities. This can lead to form errors and application malfunction.

Recommendation

Upgrade JeecgBoot beyond 3.9.5 when available and add permission checks to the importExcel handler in SysCheckRuleController. Until patched, restrict access to validation rule import functionality.
