Detailsinfo

A vulnerability, which was classified as problematic, was found in sbt up to 1.9.6. Affected is the function IO.unzip of the file /root/.ssh/authorized_keys of the component Archive File Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. 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. This is going to have an impact on integrity, and availability. CVE summarizes:

sbt is a build tool for Scala, Java, and others. Given a specially crafted zip or JAR file, `IO.unzip` allows writing of arbitrary file. This would have 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. This vulnerability has been patched in version 1.9.7.

The weakness was shared 10/23/2023 as 358. The advisory is available at github.com. This vulnerability is traded as CVE-2023-46122 since 10/16/2023. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.
