{"cve":"CVE-2022-39243","nvd":{"published":"2022-09-26T14:15:10.407","modified":"2026-06-17T04:57:59.053","status":"Modified","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-77"],"references":["https://github.com/brettwooldridge/NuProcess/commit/29bc09de561bf00ff9bf77123756363a9709f868","https://github.com/brettwooldridge/NuProcess/pull/143","https://github.com/brettwooldridge/NuProcess/security/advisories/GHSA-cxgf-v2p8-7ph7","https://github.com/brettwooldridge/NuProcess/commit/29bc09de561bf00ff9bf77123756363a9709f868","https://github.com/brettwooldridge/NuProcess/pull/143"],"products":["nuprocess_project:nuprocess"],"source":"nvd","synced_at":"2026-10-19T21:36:05.460296998+00:00"},"epss":{"cve":"CVE-2022-39243","score":0.0156,"percentile":0.75237,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cxgf-v2p8-7ph7","url":"https://osv.dev/vulnerability/GHSA-cxgf-v2p8-7ph7","summary":"NuProcess vulnerable to command-line injection through insertion of NUL character(s)","modified":"2023-11-08T04:10:16.389553Z","packages":[{"ecosystem":"Maven","name":"com.zaxxer:nuprocess","purl":"pkg:maven/com.zaxxer/nuprocess","ranges":[">=1.2.0 <2.0.5"],"fixed":["2.0.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
