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.

The remote NewStart CGSL host, running version MAIN 7.02, has cloud-init packages installed that are affected by multiple 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)

  - When instructing cloud-init to set a random password for a new user account, versions before 21.2 would     write that password to the world-readable log file /var/log/cloud-init-output.log. This could allow a     local user to log in as another user. (CVE-2021-3429)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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 Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5496-1 advisory.

    Mike Stroyan discovered that cloud-init could log password hashes when reporting schema failures. An     attacker with access to these logs could potentially use this to gain user credentials.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
