Path traversal of 'trusted_jar_paths' in Impala 4.5.2 allows an attacker-controlled JAR to be loaded via a relative path where the prefix matches a path specified in 'trusted_jar_paths'. The startup flag 'trusted_jar_paths' references URIs for loading files from local or remote filesystems. Path traversal can't override the schema, but can result in loading a JAR that has been uploaded to a different location in that filesystem via Impala DDLs such as CREATE DATA SOURCE and CREATE TABLE. Path traversal can only be used if a trusted path exists, so this attack requires 'trusted_jar_paths' have a non-empty value configured by the Impala admin. Users are recommended to upgrade to version 4.5.3, which fixes this issue.
