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.

An update of the cloud package has been released.

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2024:0128-1 advisory.

  - 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 Nessus has not tested for this issue 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.
