sbt vulnerable to arbitrary file write via archive extraction (Zip Slip)
🔗 CVE IDs covered (1)
📋 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.
