AI-suggested
- Immediate mitigation should focus on restricting access to the /serialNumber/addSerialNumber endpoint by implementing network-level controls such as IP whitelisting or VPN-only access.
- Employ Web Application Firewalls (WAFs) with rules designed to detect and block malicious serialized payloads targeting fastjson deserialization vulnerabilities.
- Monitor application logs and network traffic for unusual or unexpected serialized object patterns indicative of exploitation attempts.
- If possible, disable or replace the fastjson library with a safer alternative or upgrade to a version that includes deserialization security fixes.
- Implement strict input validation and deserialization filters to reject untrusted or malformed data before processing.
- Engage with the vendor for patches or official guidance and apply updates as soon as they become available.
- Conduct internal audits to identify all instances of fastjson usage within the ERP and related systems to ensure comprehensive coverage.
- Educate development and security teams about deserialization risks and secure coding practices to prevent future vulnerabilities.
Description
An issue was discovered in jishenghua JSH_ERP 2.3.1. The /serialNumber/addSerialNumber endpoint is vulnerable to fastjson deserialization attacks.
