CVE-2023-43123
CVSS 3.1 Score 5.5 of 10 (medium)
Details
Summary
CVE-2023-43123 introduces a vulnerability on unix-like systems where the default permissions of files created using APIs like File.createTempFile can lead to information disclosure. The temporary files, created with easily identifiable names and default permissions, can be read by other local users, potentially exposing sensitive information. This issue affects the Apache Storm class TopologySpoutLag and was introduced by STORM-3123. The impact is limited as the file is deleted soon after creation and the class is only used when ui.disable.spout.lag.monitoring is set to false. The recommended solution is to use Files.createTempFile instead, which allows for more precise control over file permissions. All users are advised to upgrade to the latest version of Apache Storm to mitigate this vulnerability.
