Microsoft fixed a security flaw in the Power Platform Custom Connectors feature that let unauthenticated attackers access cross-tenant applications and Azure customers' sensitive data after being called "Grossly irresponsible" by Tenable's CEO. The root cause of the issue stemmed from inadequate access control measures for Azure Function hosts launched by connectors within the Power Platform. "It should be noted that this is not exclusively an issue of information disclosure, as being able to access and interact with the unsecured Function hosts, and trigger behavior defined by custom connector code, could have further impact," says cybersecurity firm Tenable which discovered the flaw and reported it on March 30th. "However, because of the nature of the service, the impact would vary for each individual connector, and would be difficult to quantify without exhaustive testing."
