Summary
JeecgBoot through version 3.9.5 contains a missing authorization check in the system audit-log deletion handler. An authenticated, low-privileged user may delete audit entries, potentially including the entire system log table when the deletion function accepts a global-clear operation.
JeecgBoot through version 3.9.5 contains a missing authorization check in the system audit-log deletion handler. An authenticated, low-privileged user may delete audit entries, potentially including the entire system log table when the deletion function accepts a global-clear operation.
Affected context
The vulnerability occurs in deployments that expose JeecgBoot's SysLogController batch-deletion functionality to authenticated users without enforcing a role or permission check for destructive audit-log operations. Risk is increased when ordinary users can reach the handler and audit records are stored in the affected sys_log table.

Exploit preconditions
- Attack surface: Authenticated application HTTP endpoint
- Required access: Any valid user account, if no additional privilege check is enforced
- Trigger point: The SysLogController deleteBatch handler
- Affected operation: Batch deletion of system audit-log records
- Why exploitation is possible: Authorization is not adequately verified before a destructive operation is performed
- Attack surface: Authenticated application HTTP endpoint
- Required access: Any valid user account, if no additional privilege check is enforced
- Trigger point: The SysLogController deleteBatch handler
- Affected operation: Batch deletion of system audit-log records
- Why exploitation is possible: Authorization is not adequately verified before a destructive operation is performed
Why this happens
The underlying flaw is a missing authorization control on a sensitive administrative operation. The handler relies on authentication or request reachability without confirming that the caller has permission to delete audit records, which maps to CWE-862: Missing Authorization. This insecure pattern allows a lower-privileged principal to invoke functionality intended for trusted administrators.

Potential impact
- Attackers may delete selected audit-log entries
- Attackers could erase broad or complete audit history
- Security investigations may lose important evidence
- Organizations may experience reduced compliance and accountability
- Tampering could delay detection of other malicious activity

General mitigation guidance
Mitigation generally focuses on enforcing authorization at the server-side
operation boundary rather than relying on client-side controls or endpoint
visibility.
Common defensive patterns include:
- Require an explicit, narrowly scoped permission for audit-log deletion
- Apply role and ownership checks before processing any destructive request
- Treat global-clear operations as separate, highly privileged capabilities
- Use deny-by-default authorization for administrative handlers
- Preserve audit records through append-only or independently protected storage
- Run application and database identities with only the privileges required
- Require additional approval or separation of duties for bulk deletion

How teams detect issues like this
Organizations can identify similar issues through:
- Static analysis for controller methods that perform deletes without authorization annotations or checks
- Code review of batch, bulk, purge, and clear operations
- Tests verifying that ordinary authenticated roles receive authorization failures
- API policy enforcement requiring explicit permissions for destructive endpoints
- Monitoring for unusual volumes of audit-log deletion requests
- Database and application alerts for unexpected truncation or mass-delete activity
Automated security review tools may help identify handlers whose authorization
requirements do not match the sensitivity of their operations.
