CVE-2023-46122
sbt vulnerable to arbitrary file write via archive extraction (Zip Slip)
Description
### 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
