How to Fix CVE-2017-15288

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

org.scala-lang:scala-compiler fixed: 2.10.7 
<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-compiler</artifactId>
    <version>2.10.7</version>
</dependency>
org.scala-lang:scala-compiler fixed: 2.11.12 
<dependency>
    <groupId>org.scala-lang</groupId>

<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-compiler</artifactId>
    <version>2.12.4</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=org.scala-lang

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2017-15288, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.scala-lang

Analyze the terminal output to locate any version of Scala compiler in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.10.7), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.scala-lang 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-732: Incorrect Permission Assignment for Critical Resource, where the product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. In Scala compiler, 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

The compilation daemon in Scala before 2.10.7, 2.11.x before 2.11.12, and 2.12.x before 2.12.4 uses weak permissions for private files in /tmp/scala-devel/${USER:shared}/scalac-compile-server-port, which allows local users to write to arbitrary class files and consequently gain privileges.
