AI-suggested
- Immediately restrict network access to the /materialCategory/addMaterialCategory endpoint using firewalls or API gateways to limit exposure to trusted internal networks.
- Implement strict input validation and JSON schema validation to reject unexpected or malformed payloads before deserialization.
- If possible, disable or replace the fastjson library with a safer alternative or configure it to disallow polymorphic deserialization features that enable code execution.
- Monitor logs and network traffic for anomalous requests targeting the vulnerable endpoint, including unusual JSON payloads or spikes in traffic.
- Engage with the vendor to obtain patches or security advisories and apply updates as soon as they become available.
- Conduct penetration testing and code audits focusing on deserialization and input handling in the ERP system.
- Prepare incident response plans specifically addressing potential exploitation scenarios involving this vulnerability.
- Consider network segmentation to isolate ERP systems from less trusted environments.
- Educate development and security teams about the risks of unsafe deserialization and secure coding practices.
Description
An issue was discovered in jishenghua JSH_ERP 2.3.1. The /materialCategory/addMaterialCategory endpoint is vulnerable to fastjson deserialization attacks.
