Vulnerability

Improper Neutralization of Special Elements used in a Command ('Command Injection')

Description

NuProcess is an external process execution implementation for Java. In all the versions of NuProcess where it forks processes by using the JVM's JavajavalangUNIXProcessforkAndExec method (1.2.0+), attackers can use NUL characters in their strings to perform command line injection. Java's ProcessBuilder isn't vulnerable because of a check in ProcessBuilder.start. NuProcess is missing that check. This vulnerability can only be exploited to inject command line arguments on Linux. Version 2.0.5 contains a patch. As a workaround, users of the library can sanitize command strings to remove NUL characters prior to passing them to NuProcess for execution.

Affected Versions

All versions starting from 1.2.0 before 2.0.5

Solution

Upgrade to version 2.0.5 or above.
