{"id":"CVE-2022-41954","aliases":["GHSA-jf2p-4gqj-849g","PYSEC-2022-42996"],"url":"https://o3.security/vulnerability/CVE-2022-41954","summary":"Temporary File Information Disclosure Vulnerability","details":"### Impact\nOn Unix-like operating systems (not Windows or macos), MPXJ's use of `File.createTempFile(..)` results in temporary files being created with the permissions `-rw-r--r--`. This means that any other user on the system can read the contents of this file. When MPXJ is reading a type of schedule file which requires the creation of a temporary file or directory, a knowledgeable local user could locate these transient files while they are in use and would then be able to read the schedule being processed by MPXJ.\n\n### Patches\nThe problem has been patched, MPXJ version 10.14.1 and later includes the necessary changes.\n\n### Workarounds\nSetting `java.io.tmpdir` to a directory to which only the user running the application has access will prevent other users from accessing these temporary files.\n\n### For more information\nIf you have any questions or comments about this advisory\n* Open an issue in https://github.com/joniles/mpxj\n","published":"2022-11-25T00:00:00Z","modified":"2026-08-12T13:33:32.424350Z","cvss":{"score":3.3,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":{"score":0.00213,"percentile":0.1187,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"net.sf.mpxj:mpxj","fixedVersion":"10.14.1"},{"ecosystem":"NuGet","name":"net.sf.mpxj","fixedVersion":"10.14.1"},{"ecosystem":"NuGet","name":"net.sf.mpxj-for-csharp","fixedVersion":"10.14.1"},{"ecosystem":"NuGet","name":"net.sf.mpxj-for-vb","fixedVersion":"10.14.1"},{"ecosystem":"PyPI","name":"mpxj","fixedVersion":"10.14.1"}],"fix":{"url":"https://github.com/joniles/mpxj/commit/ae0af24345d79ad45705265d9927fe55e94a5721","label":"joniles/mpxj@ae0af24"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/41xxx/CVE-2022-41954.json"},{"type":"ADVISORY","url":"https://github.com/joniles/mpxj/security/advisories/GHSA-jf2p-4gqj-849g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-41954"},{"type":"FIX","url":"https://github.com/joniles/mpxj/commit/ae0af24345d79ad45705265d9927fe55e94a5721"},{"type":"WEB","url":"https://github.com/joniles/mpxj/commit/287ad0234213c52b0638565e14bd9cf3ed44cedd"},{"type":"PACKAGE","url":"https://github.com/joniles/mpxj"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/mpxj/PYSEC-2022-42996.yaml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T13:33:32.424350Z"}}
