Technical Analysis
This vulnerability (CWE-862) in KNIME Business Hub versions before 1.19.0 involves a missing authorization check. Specifically, users who have access to a 'link without login' for a DataApp can list and potentially access jobs created by other users using the same link. This issue arises because the system does not properly verify user permissions for these shared links, allowing unauthorized access to job information.
Potential Impact
An attacker or unauthorized user with access to a 'link without login' can enumerate and potentially access jobs of other users created via the same link. This could lead to unauthorized disclosure of job data within the KNIME Business Hub environment. The impact is limited to users who have access to such links and does not require authentication or privileges beyond that.
Mitigation Recommendations
A workaround is to remove all 'links without login' to DataApps to prevent unauthorized access. Since no official patch or fix is indicated in the provided data, users should apply this workaround until an official fix is released. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
