WebLogic Incorrect Permission Assignment for Critical Resource Vulnerability - CVE-2020-8908

A temp directory creation vulnerability exists in all versions of Guava allowing an attacker with access to the machine to potentially access data in a temporary directory created by the Guava API com.google.common.io.Files.createTempDir(). By default on unix-like systems the created directory is world-readable (readable by an attacker with access to the system). The method in question has been marked Deprecated in versions 30.0 and later and should not be used. For Android developers we recommend choosing a temporary directory API provided by Android such as context.getCacheDir(). For other Java developers we recommend migrating to the Java 7 API java.nio.file.Files.createTempDirectory() which explicitly configures permissions of 700 or configuring the Java runtime39s java.io.tmpdir system property to point to a location whose permissions are appropriately configured.
