CVE-2022-39243
8.4 · HIGHOverview
CVE-2022-39243 is a high-severity vulnerability affecting nuprocess_project nuprocess. It was published on September 26, 2022 and has a CVSS 3.1 base score of 8.4 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical 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 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.
Remediation
Check the references section for vendor advisories and patches from nuprocess_project. Update nuprocess to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
