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-2021-33542 in the wild and no public exploit code.\n\nAffected product: Phoenix Contact Automation Worx Software Suite. 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-2021-33542/ (Markdown: https://insights.sbomify.com/CVE-2021-33542/index.md)","id":"CVE-2021-33542","markdown":"https://insights.sbomify.com/CVE-2021-33542/index.md","name":"CVE-2021-33542","record":{"aliases":["GHSA-88r6-jjq4-269q"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Industrial automation software","requires_auth":"none","summary":"Attackers can execute arbitrary code on programming workstations by tricking users into opening manipulated project files, compromising system integrity and availability.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"config\\+","vendor":"phoenixcontact"},{"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-824","name":"Access of Uninitialized Pointer"}],"description":"Phoenix Contact Classic Automation Worx Software Suite in Version 1.87 and below is affected by a remote code execution vulnerability. Manipulated PC Worx or Config+ projects could lead to a remote code execution when unallocated memory is freed because of incompletely initialized data. The attacker needs to get access to an original bus configuration file (*.bcp) to be able to manipulate data inside. After manipulation the attacker needs to exchange the original file by the manipulated one on the application programming workstation. Availability, integrity, or confidentiality of an application programming workstation might be compromised by attacks using these vulnerabilities. Automated systems in operation which were programmed with one of the above-mentioned products are not affected.","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: Automation Worx Software Suite affected by Remote Code Execution (RCE) vulnerability","id":"CVE-2021-33542","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"UDP Technology/Geutebrück camera devices: Authentication Bypass","id":"CVE-2021-33543"},"packages":[],"prev":{"headline":"Phoenix Contact: ILC1x Industrial controllers affected by Denial-of-Service vulnerability","id":"CVE-2021-33541"},"products":["Automation Worx Software Suite"],"published":"2021-06-25","related":[{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2019-16675","kev_date_added":null,"published":"2019-10-31"}],"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":"2024-09-17","vendors":["Phoenix Contact"]},"summary":"Attackers can execute arbitrary code on programming workstations by tricking users into opening manipulated project files, compromising system integrity and availability.","url":"https://insights.sbomify.com/CVE-2021-33542/"}
