• Possible escalation of privileges for low-privileged users
• Risk of unauthorized access to sensitive data or systems
• Need for verification of authorization checks in SysDepartPermissionController

Technical summary

The vulnerability exists in the SysDepartPermissionController of JeecgBoot through 3.9.5. An authenticated user can modify department permission records by calling the edit endpoint, allowing low-privileged attackers to alter depart_id, permission_id, and data_rule_ids. This could lead to unauthorized modification of department permissions, possible escalation of privileges for low-privileged users, and risk of unauthorized access to sensitive data or systems. Defenders should prioritize verifying and restricting access to the SysDepartPermissionController's edit endpoint, ensuring proper authorization checks are in place, and monitoring for suspicious modifications to department permissions

Defensive priority

Defenders should prioritize verifying and restricting access to the SysDepartPermissionController's edit endpoint, ensuring proper authorization checks are in place, and monitoring for suspicious modifications to department permissions.

Recommended defensive actions

• Verify and restrict access to the SysDepartPermissionController's edit endpoint
• Ensure proper authorization checks are in place for modifying department permissions
• Monitor for suspicious modifications to department permissions
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and NVD entry provide details on the vulnerability. However, the exact scope of affected versions and systems requires further verification from official sources. Affected product deployments need to be confirmed in managed environments. Defenders should verify and restrict access to the SysDepartPermissionController's edit endpoint, ensuring proper authorization checks are in place. Low-privileged users may be able to exploit this vulnerability to modify department permissions, potentially leading to unauthorized data
