An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21001 in the wild and no public exploit code.\n\nAffected product: WAGO Series Ethernet Controller. 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-2021-21001/ (Markdown: https://insights.sbomify.com/CVE-2021-21001/index.md)","id":"CVE-2021-21001","markdown":"https://insights.sbomify.com/CVE-2021-21001/index.md","name":"CVE-2021-21001","record":{"aliases":["GHSA-52pm-rch7-vfc5"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WAGO PFC200 Controller","requires_auth":"high_privilege","summary":"An authorized attacker can access files outside the home directory with higher privileges on WAGO PFC200 controllers via crafted packets.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"750-8202_firmware","vendor":"wago"},{"product":"750-8203_firmware","vendor":"wago"},{"product":"750-8204_firmware","vendor":"wago"},{"product":"750-8206_firmware","vendor":"wago"},{"product":"750-8207_firmware","vendor":"wago"},{"product":"750-8208_firmware","vendor":"wago"},{"product":"750-8210_firmware","vendor":"wago"},{"product":"750-8211_firmware","vendor":"wago"},{"product":"750-8212_firmware","vendor":"wago"},{"product":"750-8213_firmware","vendor":"wago"},{"product":"750-8214_firmware","vendor":"wago"},{"product":"750-8216_firmware","vendor":"wago"},{"product":"750-8217_firmware","vendor":"wago"},{"product":"750-823_firmware","vendor":"wago"},{"product":"750-829_firmware","vendor":"wago"},{"product":"750-831_firmware","vendor":"wago"},{"product":"750-832_firmware","vendor":"wago"},{"product":"750-852_firmware","vendor":"wago"},{"product":"750-862_firmware","vendor":"wago"},{"product":"750-880_firmware","vendor":"wago"},{"product":"750-881_firmware","vendor":"wago"},{"product":"750-882_firmware","vendor":"wago"},{"product":"750-885_firmware","vendor":"wago"},{"product":"750-889_firmware","vendor":"wago"},{"product":"750-890_firmware","vendor":"wago"},{"product":"750-891_firmware","vendor":"wago"},{"product":"750-893_firmware","vendor":"wago"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"On WAGO PFC200 devices in different firmware versions with special crafted packets an authorised attacker with network access to the device can access the file system with higher privileges.","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":"WAGO: PFC200 Access to files outside the home directory","id":"CVE-2021-21001","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":"Denial of Service in Phoenix Contact FL COMSERVER UNI products","id":"CVE-2021-21002"},"packages":[],"prev":{"headline":"WAGO: PFC200 Denial of Service due to the number of connections to the runtime","id":"CVE-2021-21000"},"products":["Series Ethernet Controller","Series PFC200 Controller"],"published":"2021-05-24","related":[{"cvss_score":5.3,"headline":"WAGO: PFC200 Denial of Service due to the number of connections to the runtime","id":"CVE-2021-21000","kev_date_added":null,"published":"2021-05-24"}],"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":["WAGO"]},"summary":"An authorized attacker can access files outside the home directory with higher privileges on WAGO PFC200 controllers via crafted packets.","url":"https://insights.sbomify.com/CVE-2021-21001/"}
