{"id":"GHSA-cxgf-v2p8-7ph7","summary":"NuProcess vulnerable to command-line injection through insertion of NUL character(s)","details":"### Impact\nIn 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.\n\nThis vulnerability can only be exploited to inject command line arguments on Linux.\n- 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.\n- 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.\n\n### Patches\n2.0.5\n\n### Workarounds\nUsers of the library can sanitize command strings to remove NUL characters prior to passing them to NuProcess for execution.\n\n### References\nNone.\n","aliases":["CVE-2022-39243"],"modified":"2023-11-08T04:10:16.389553Z","published":"2022-09-30T04:29:11Z","database_specific":{"github_reviewed_at":"2022-09-30T04:29:11Z","nvd_published_at":"2022-09-26T14:15:00Z","cwe_ids":["CWE-77"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/brettwooldridge/NuProcess/security/advisories/GHSA-cxgf-v2p8-7ph7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39243"},{"type":"WEB","url":"https://github.com/brettwooldridge/NuProcess/pull/143"},{"type":"WEB","url":"https://github.com/brettwooldridge/NuProcess/commit/29bc09de561bf00ff9bf77123756363a9709f868"},{"type":"PACKAGE","url":"https://github.com/brettwooldridge/NuProcess"}],"affected":[{"package":{"name":"com.zaxxer:nuprocess","ecosystem":"Maven","purl":"pkg:maven/com.zaxxer/nuprocess"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.2.0"},{"fixed":"2.0.5"}]}],"versions":["1.2.0","1.2.1","1.2.2","1.2.3","1.2.4","1.2.5","1.2.6","2.0.0","2.0.1","2.0.2","2.0.3","2.0.4"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-cxgf-v2p8-7ph7/GHSA-cxgf-v2p8-7ph7.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
