Description
sbt is a build tool for Scala, Java, and others. From version 0.9.5 to before version 1.12.7, on Windows, sbt uses Process("cmd", "/c", ...) to run VCS commands (git, hg, svn). The URI fragment (branch, tag, revision) is user-controlled via the build definition and passed to these commands without validation. Because cmd /c interprets &, |, and ; as command separators, a malicious fragment can execute arbitrary commands. This issue has been patched in version 1.12.7.
