According to the versions of the cloud-init package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Sensitive data could be exposed in world readable logs of cloud-init before version 22.3 when schema     failures are reported. This leak could include hashed passwords. (CVE-2022-2084)

  - Sensitive data could be exposed in logs of cloud-init before version 23.1.2. An attacker could use this     information to find hashed passwords and possibly escalate their privilege. (CVE-2023-1786)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Oracle Linux 9 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2023-12299 advisory.
