It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-34597 in the wild and no public exploit code.\n\nAffected product: Phoenix Contact PC Worx. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2021-34597/ (Markdown: https://insights.sbomify.com/CVE-2021-34597/index.md)","id":"CVE-2021-34597","markdown":"https://insights.sbomify.com/CVE-2021-34597/index.md","name":"CVE-2021-34597","record":{"aliases":["GHSA-m8p2-4fmh-2gr9"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Industrial automation software","requires_auth":"none","summary":"Attackers can use manipulated project files to unpack arbitrary files outside the intended directory in Phoenix Contact PC Worx.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"pc_worx","vendor":"phoenixcontact"},{"product":"pc_worx_express","vendor":"phoenixcontact"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper Input Validation vulnerability in PC Worx Automation Suite of Phoenix Contact up to version 1.88 could allow an attacker with a manipulated project file to unpack arbitrary files outside of the selected project directory.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Phoenix Contact: PC Worx/-Express prone to improper input validation vulnerability","id":"CVE-2021-34597","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Phoenix Contact: FL MGUARD lack of memory release in remote logging functionality","id":"CVE-2021-34598"},"packages":[],"prev":{"headline":"CODESYS V2 runtime: Access of Uninitialized Pointer may result in denial-of-service","id":"CVE-2021-34596"},"products":["PC Worx"],"published":"2021-11-04","related":[{"cvss_score":7.8,"headline":"Phoenix Contact Automation Worx \u003c= 1.87: stack-based overflow","id":"CVE-2020-12497","kev_date_added":null,"published":"2020-07-01"},{"cvss_score":7.8,"headline":"Phoenix Contact Automation Worx \u003c= 1.87: out-of-bounds read remote code execution","id":"CVE-2020-12498","kev_date_added":null,"published":"2020-07-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Phoenix Contact"]},"summary":"Attackers can use manipulated project files to unpack arbitrary files outside the intended directory in Phoenix Contact PC Worx.","url":"https://insights.sbomify.com/CVE-2021-34597/"}
