Attack-Flow Graph

Executive Summary

JeecgBoot through version 3.9.5 has a missing authorization vulnerability. Low-privileged authenticated users can modify message templates by sending a PUT request to /sys/message/sysMessageTemplate/edit. Attackers can first obtain template IDs from an unprotected list endpoint and then overwrite system notification titles and content with their own text or links.

Detection Guidance

Check for unauthorized PUT requests to /sys/message/sysMessageTemplate/edit. Monitor logs for low-privileged users accessing message template endpoints. Verify if template IDs are exposed via unprotected list endpoints.

Impact Analysis

This vulnerability allows attackers to alter system notifications, potentially replacing legitimate messages with malicious content like phishing links or fake alerts. Users receiving these notifications may be tricked into disclosing sensitive information or downloading malware.

Compliance Impact

This vulnerability could lead to unauthorized data exposure or manipulation of notifications, potentially violating GDPR (data protection) and HIPAA (health information privacy) by enabling phishing attacks or unauthorized access to user data.

Mitigation Strategies

Apply patches or updates to JeecgBoot version 3.9.5 or later. Restrict access to /sys/message/sysMessageTemplate/edit endpoint. Review and audit user permissions to ensure least privilege. Monitor for suspicious template modifications.
