Summary

qKnow through 2.4.3 contains a missing authentication vulnerability that allows unauthenticated remote attackers to access /flyflow workflow integration endpoints permitted in SecurityConfig. Attackers can POST sequential userId values to /flyflow/userById or call roleAll and deptListByParentDeptId to enumerate user phone numbers, roles, and department structure.

Risk Assessment

The vulnerability allows unauthorized access to employees' personal data, including phone numbers and roles, which may facilitate social engineering attacks. The organization may face reputational damage and violate data protection regulations.

Recommendation

Update qKnow to a version later than 2.4.3 or apply the vendor patch. It is also recommended to implement authentication for all /flyflow endpoints.
