How to Fix CVE-2020-15087

To remediate this vulnerability, upgrade all affected Presto server dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.prestosql:presto-server fixed: 337 
<dependency>
    <groupId>io.prestosql</groupId>
    <artifactId>presto-server</artifactId>
    <version>337</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=io.prestosql

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-15087, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.prestosql

Analyze the terminal output to locate any version of Presto server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 337), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.prestosql command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In Presto server, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Affected This affects Presto server installations. This does NOT affect clients such as the CLI or JDBC driver. ### Impact Authenticated users can bypass authorization checks by directly accessing internal APIs. This impacts Presto server installations with secure internal communication configured. This does not affect installations that have not configured secure internal communication, as these installations are inherently insecure. ### Patches This issue has been fixed starting with PrestoSQL version 337. ### Workarounds This issue can be mitigated by blocking network access to internal APIs on the coordinator and workers. ### References See the Presto documentation for [Secure Internal Communication](https://trino.io/docs/current/security/internal-communication.html). ### For more information If you have any questions or comments about this advisory: * Join the **#security** channel on [Slack](https://trino.io/slack.html). * Contact the security team at [security@trino.io](mailto:security@trino.io)
