GHSA-846g-p7hm-f54r
No affected components available
Amazon AWS Amplify CLI before 12.10.1 incorrectly configures the role trust policy of IAM roles associated with Amplify projects. When the Authentication component is removed from an Amplify project, a Condition property is removed but "Effect":"Allow" remains present, and consequently sts:AssumeRoleWithWebIdentity would be available to threat actors with no conditions. Thus, if Amplify CLI had been used to remove the Authentication component from a project built between August 2019 and January 2024, an "assume role" may have occurred, and may have been leveraged to obtain unauthorized access to an organization's AWS resources. NOTE: the problem could only occur if an authorized AWS user removed an Authentication component. (The vulnerability did not give a threat actor the ability to remove an Authentication component.) However, in realistic situations, an authorized AWS user may have removed an Authentication component, e.g., if the objective were to stop using built-in Cognito resources, or move to a completely different identity provider.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
