maven com.amazonaws:codedeploy (Maven)

Affected versions

Patched versions

Description

Jenkins project Jenkins AWS CodeDeploy Plugin version 1.19 and earlier contains a Insufficiently Protected Credentials vulnerability in AWSCodeDeployPublisher.java that can result in Credentials Disclosure. This attack appears to be exploitable via local file access.

AWS CodeDeploy Plugin 1.20 and newer stores the AWS Secret Key encrypted in the configuration files on disk and no longer transfers it to users viewing the configuration form in plain text. Existing jobs need to have their configuration saved for existing plain text secret keys to be overwritten.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
