Amazon Fixes a Security Vulnerability Affecting AWS AppSync

[vc_row pix_particles_check=”” nav_skin=”light” consent_include=”include”][vc_column][vc_column_text]A security vulnerability called “cross-tenant” has been detected by Datadog researchers in AppSync, a popular Amazon Web Services (AWS) tool. AppSync is a popular AWS service that allows developers to quickly create GraphQL and Pub/Sub APIs.

The vulnerability is due to a case-sensitivity parsing issue of the AppSync service that could potentially be used to bypass cross-account role usage validations and act as a service on customer accounts. Successful vulnerability exploitation allows threat actors to assume Identity and Access Management (IAM) roles in other AWS accounts.[/vc_column_text][vc_empty_space height=”10px”][vc_single_image image=”17000″ img_size=”full” add_caption=”yes” alignment=”center”][vc_empty_space height=”10px”][vc_column_text]The vulnerability detected on September 1, 2022, was immediately reported to AWS.

There is no action for Amazon customers to take due to the vulnerability.[/vc_column_text][vc_empty_space][/vc_column][/vc_row]
