Attack-Flow Graph

Executive Summary

JeecgBoot through version 3.9.5 has a missing authorization vulnerability. Low-privileged authenticated users can create message templates by sending a POST request to /sys/message/sysMessageTemplate/add. This allows attackers with minimal roles to insert arbitrary notification templates into the shared sys_sms_template library, which is used for system, email, SMS, and IM notifications.

Detection Guidance

Check for unauthorized POST requests to /sys/message/sysMessageTemplate/add by reviewing web server or application logs for suspicious activity. Look for low-privileged users creating or modifying message templates.

Impact Analysis

An attacker could exploit this to inject malicious or misleading notification templates into the system. This could lead to unauthorized messages being sent to users, potentially spreading misinformation, phishing attempts, or disrupting normal system operations. The impact depends on how the system uses these templates for notifications.

Compliance Impact

This vulnerability could lead to unauthorized data exposure or manipulation of notifications, which may violate compliance requirements under GDPR (data protection) or HIPAA (health information privacy). Unauthorized message content could result in breaches of confidentiality or integrity, potentially leading to regulatory penalties.

Mitigation Strategies

Update JeecgBoot to version 3.9.5 or later. Restrict access to the /sys/message/sysMessageTemplate/add endpoint by implementing proper authorization checks. Audit existing message templates for unauthorized changes.
