CVE-2023-43123— Apache Storm: Local Information Disclosure Vulnerability in Storm-core on Unix-Like systems due temporary files

Quick assessment

Affected
Apache Software Foundation Apache Storm
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Storm是美国阿帕奇（Apache）基金会的一套采用Clojure（并发编程语言）开发的开源分布式实时计算系统。 Apache Storm 2.6.0之前的2.0.0版本存在信息泄露漏洞，该漏洞源于临时目录在所有用户之间共享，允许攻击者使用未明确设置权限的API写入该目录，从而导致敏感信息泄露。

Vulnerability Title
Apache Storm: Local Information Disclosure Vulnerability in Storm-core on Unix-Like systems due temporary files
Source: CVE Program / CVE List V5
Vulnerability Description
On unix-like systems, the temporary directory is shared between all user. As such, writing to this directory using APIs that do not explicitly set the file/directory permissions can lead to information disclosure. Of note, this does not impact modern MacOS Operating Systems. The method File.createTempFile on unix-like systems creates a file with predefined name (so easily identifiable) and by default will create this file with the permissions -rw-r--r--. Thus, if sensitive information is written to this file, other local users can read this information. File.createTempFile(String, String) will create a temporary file in the system temporary directory if the 'java.io.tmpdir' system property is not explicitly set. This affects the class  https://github.com/apache/storm/blob/master/storm-core/src/jvm/org/apache/storm/utils/TopologySpoutLag.java#L99  and was introduced by  https://issues.apache.org/jira/browse/STORM-3123 In practice, this has a very limited impact as this class is used only if ui.disable.spout.lag.monitoring is set to false, but its value is true by default. Moreover, the temporary file gets deleted soon after its creation. The solution is to use  Files.createTempFile https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/file/Files.html#createTempFile(java.lang.String,java.lang.String,java.nio.file.attribute.FileAttribute...)  instead. We recommend that all users upgrade to the latest version of Apache Storm.
