Amazon CloudWatch Agent for Windows has Privilege Escalation Vector

High severity GitHub Reviewed Published Dec 10, 2022 in aws/amazon-cloudwatch-agent • Updated Apr 3, 2023

Package

gomod github.com/aws/amazon-cloudwatch-agent (Go)

Affected versions

< 1.247355.0

Patched versions

1.247355.0

Description

Impact

A privilege escalation issue exists within the Amazon CloudWatch Agent for Windows in versions up to and including v1.247354. When users trigger a repair of the Agent, a pop-up window opens with SYSTEM permissions. Users with administrative access to affected hosts may use this to create a new command prompt as NT AUTHORITY\SYSTEM.

To trigger this issue, the third party must be able to access the affected host and elevate their privileges such that they’re able to trigger the agent repair process. They must also be able to install the tools required to trigger the issue.

This issue does not affect the CloudWatch Agent for macOS or Linux.

Patches

Maintainers recommend that Agent users upgrade to the latest available version of the CloudWatch Agent to address this issue.

Workarounds

There is no recommended work around. Affected users must update the installed version of the CloudWatch Agent to address this issue.

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.
