How to Fix CVE-2023-46122

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

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-sbt

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-46122, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Sbt in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.9.7), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.scala-sbt 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Sbt, 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

### Impact Given specially crafted zip or JAR file, `IO.unzip` allows writing of arbitrary file. The follow is an example of a malicious entry: ``` +2018-04-15 22:04:42 ..... 20 20 ../../../../../../root/.ssh/authorized_keys ``` This would have a potential to overwrite `/root/.ssh/authorized_keys`. Within sbt's main code, `IO.unzip` is used in `pullRemoteCache` task and `Resolvers.remote`; however many projects use `IO.unzip(...)` directly to implement custom tasks - https://github.com/search?q=IO.unzip+language%3AScala&type=code&l=Scala&p=1 ### Patches The problem has been patched in https://github.com/sbt/io/pull/360 sbt 1.9.7 is available with the fix. ### Workarounds A workaround might be use some other library to unzip. ### References - https://github.com/snyk/zip-slip-vulnerability - https://security.snyk.io/vuln/SNYK-JAVA-ORGCODEHAUSPLEXUS-31680 - https://github.com/sbt/io/issues/358
