Synopsis
The remote host is missing a security update.
Description
The version of Amazon CloudWatch Agent installed on the remote host is prior to 1.247355. It is, therefore, affected by a vulnerability as referenced in the GHSA-j8x2-2m5w-j939 advisory.
- A privilege escalation issue exists within the Amazon CloudWatch Agent for Windows, software for collecting metrics and logs from Amazon EC2 instances and on-premises servers, 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. Agent users should upgrade to version 1.247355 of the CloudWatch Agent to address this issue. There is no recommended work around. Affected users must update the installed version of the CloudWatch Agent to address this issue. (CVE-2022-23511)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade Amazon CloudWatch Agent based upon the guidance specified in GHSA-j8x2-2m5w-j939.
