Severity: important
Affected versions:
- Apache Impala 2.0.0 through 4.5.1
Description:
Specifying tblproperties('avro.schema.url'=' http://...' ) or with a 'file:///'
URI on a table in Impala 2.0.0 to 4.5.1 on all platforms allows an attacker to
trigger a GET request to internal endpoints they may not have access to but
that Impala does and the response my be exposed via parsing error messages.
Users are recommended to upgrade to version 4.5.2, which fixes this issue.
