Detailsinfo

A vulnerability was found in NuProcess up to 2.0.4. It has been rated as critical. Affected by this issue is the function Java_java_lang_UNIXProcess_forkAndExec of the component Command Line Argument Handler. The manipulation with an unknown input leads to a command injection vulnerability. Using CWE to declare the problem leads to CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was presented 09/27/2022 as GHSA-cxgf-v2p8-7ph7. The advisory is available at github.com. This vulnerability is handled as CVE-2022-39243 since 09/02/2022. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

Upgrading to version 2.0.5 eliminates this vulnerability. Applying the patch 29bc09de561bf00ff9bf77123756363a9709f868 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
