Title
Vulnerability in nuprocess before 2.0.5 (CVE-2022-39243)
Description
### ImpactIn 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.- On macOS, any argument with a NUL character is truncated at that character. This means the malicious arguments are never seen by the started process.- On Windows, the entire command line is truncated at the first NUL character. This means the malicious arguments, and any intentional arguments provided after them, are never seen by the started process.### Patches2.0.5### WorkaroundsUsers of the library can sanitize command strings to remove NUL characters prior to passing them to NuProcess for execution.### ReferencesNone.

Comment
: 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.
