An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-35460 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- net.sf.mpxj:mpxj (Maven): affected all versions; fixed in 8.3.5\n- net.sf.mpxj:mpxj (Maven): affected all versions; fixed in 8.3.5\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-35460/ (Markdown: https://insights.sbomify.com/CVE-2020-35460/index.md)","id":"CVE-2020-35460","markdown":"https://insights.sbomify.com/CVE-2020-35460/index.md","name":"CVE-2020-35460","record":{"aliases":["GHSA-p9j6-4pjr-gp48"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"MPXJ Java library","requires_auth":"none","summary":"Attackers can write files to arbitrary locations via directory traversal in the zip stream handler of the MPXJ library.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mpxj","vendor":"mpxj"},{"product":"primavera_unifier","vendor":"oracle"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"common/InputStreamHelper.java in Packwood MPXJ before 8.3.5 allows directory traversal in the zip stream handler flow, leading to the writing of files to arbitrary locations.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2025-08-17","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-08-17T09:10:07Z","kind":"github_poc","ref":"https://github.com/shoucheng3/joniles__mpxj_CVE-2020-35460_8-3-4","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"MPXJ path Traversal vulnerability","id":"CVE-2020-35460","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"oracle:primavera_unifier","products":["oracle:primavera_unifier"],"type":"path_traversal","year":"2020"},"n_packages":2,"n_references":3,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2020-35462"},"packages":[{"ecosystem":"Maven","fixed":["8.3.5"],"introduced":["0"],"last_affected":[],"package":"net.sf.mpxj:mpxj","purl":null,"source":"GHSA-p9j6-4pjr-gp48"},{"ecosystem":"Maven","fixed":["8.3.5"],"introduced":["0"],"last_affected":[],"package":"net.sf.mpxj:mpxj","purl":"pkg:maven/net.sf.mpxj/mpxj","source":"GHSA-p9j6-4pjr-gp48"}],"prev":{"headline":"ClusterLabs crmsh vulnerable to shell code injection","id":"CVE-2020-35459"},"products":["n/a"],"published":"2020-12-14","related":[{"cvss_score":9.8,"headline":"Improper Restriction of XML External Entity Reference in MPXJ","id":"CVE-2020-25020","kev_date_added":null,"published":"2020-08-29"},{"cvss_score":3.3,"headline":"Temporary File Information Disclosure Vulnerability","id":"CVE-2022-41954","kev_date_added":null,"published":"2022-11-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-05","vendors":["n/a"]},"summary":"Attackers can write files to arbitrary locations via directory traversal in the zip stream handler of the MPXJ library.","url":"https://insights.sbomify.com/CVE-2020-35460/"}
