Executive Summary

This vulnerability is an Insecure Direct Object Reference (IDOR) in Kiteworks Secure Data Forms prior to version 9.3.0. It allows an authenticated user to modify permissions on resources that belong to other users because the system does not properly check whether the user owns the resource before allowing permission changes.

Impact Analysis

The vulnerability can lead to unauthorized modification of permissions on other users' resources. This means an attacker with valid credentials could potentially gain access to or alter data they should not have permission to, leading to data exposure or misuse.

Mitigation Strategies

Upgrade Kiteworks to version 9.3.0 or later to receive a patch that fixes the Insecure Direct Object Reference (IDOR) vulnerability.

Compliance Impact

The vulnerability in Kiteworks Secure Data Forms allows an authenticated user to modify permissions on resources belonging to other users due to insufficient authorization checks. This could lead to unauthorized access or modification of sensitive data.

Such unauthorized access or modification of data can negatively impact compliance with data protection standards and regulations like GDPR and HIPAA, which require strict controls over access to personal and sensitive information.

Organizations using affected versions of Kiteworks may face increased risk of data breaches or unauthorized data exposure, potentially resulting in regulatory penalties or loss of trust.

Upgrading to Kiteworks version 9.3.0 or later is necessary to mitigate this risk and maintain compliance.
