CVE-2022-39243 (GCVE-0-2022-39243)
Vulnerability from nvd – Published: 2022-09-26 13:25 – Updated: 2025-04-22 17:20

Title
NuProcess vulnerable to command-line injection through insertion of NUL character(s)
Summary
NuProcess is an external process execution implementation for Java. In all the versions of NuProcess where it forks processes by using the JVM's Java_java_lang_UNIXProcess_forkAndExec 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.
