Microsoft Power Pages Misconfigurations Expose Sensitive Data: Experts Warn
A recent search revealed no specific cases of organizations exposing sensitive data through misconfigurations in Microsoft Power Pages. However, experts warn that missteps in managing permissions and security settings can lead to significant data exposure. A recent incident involving an NHS service provider underscores this risk.
Microsoft Power Pages, used by over 250 million users and leading organizations, simplifies website creation and data integration. However, mismanagement of its security controls has resulted in data leaks. A service provider for the NHS inadvertently exposed over 1.1 million NHS employees' data due to a misconfiguration in Power Pages.
Misconfigurations in Power Pages can include granting unrestricted access to external users, allowing public registration for internal-level permissions, failing to enable column-level security, and lacking masking for sensitive data. To secure Power Pages deployments, firms should review site, table, and column permissions thoroughly and use a layered approach to security. Power Pages includes column security and masking options to limit exposure and protect sensitive data from unauthorized access. Administrators should heed backend warnings about potential risks when setting permissions.
Misconfigurations in Microsoft Power Pages are leading to significant data exposure, risking sensitive data including personally identifiable information (PII). Organizations should balance ease of use with security when managing external-facing websites in SaaS platforms.
