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-2020-12506 in the wild and no public exploit code.\n\nAffected product: WAGO 750-362. 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-2020-12506/ (Markdown: https://insights.sbomify.com/CVE-2020-12506/index.md)","id":"CVE-2020-12506","markdown":"https://insights.sbomify.com/CVE-2020-12506/index.md","name":"CVE-2020-12506","record":{"aliases":["GHSA-8c2w-ph9m-jcmf"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WAGO I/O System","requires_auth":"none","summary":"Attackers can modify device settings without authentication on vulnerable WAGO I/O controllers, requiring firmware updates to mitigate.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"750-362_firmware","vendor":"wago"},{"product":"750-363_firmware","vendor":"wago"},{"product":"750-823_firmware","vendor":"wago"},{"product":"750-832_firmware","vendor":"wago"},{"product":"750-862_firmware","vendor":"wago"},{"product":"750-890_firmware","vendor":"wago"},{"product":"750-891_firmware","vendor":"wago"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Improper Authentication vulnerability in WAGO 750-8XX series with FW version \u003c= FW03 allows an attacker to change the settings of the devices by sending specifically constructed requests without authentication This issue affects: WAGO 750-362, WAGO 750-363, WAGO 750-823, WAGO 750-832/xxx-xxx, WAGO 750-862, WAGO 750-891, WAGO 750-890/xxx-xxx in versions FW03 and prior versions.","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: Authentication Bypass Vulnerability in WAGO 750-36X and WAGO 750-8XX Versions \u003c= FW03","id":"CVE-2020-12506","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"s::can moni::tools autheticated SQL injection","id":"CVE-2020-12507"},"packages":[],"prev":{"headline":"WAGO: Vulnerability in web-based authentication in WAGO 750-8XX Version \u003c= FW07","id":"CVE-2020-12505"},"products":["750-362","750-363","750-823","750-832/xxx-xxx","750-862","750-890/xxx-xxx","750-891"],"published":"2020-09-30","related":[{"cvss_score":9.8,"headline":"WAGO: Authentication Vulnerability in Web-Based Management","id":"CVE-2021-34578","kev_date_added":null,"published":"2021-08-31"}],"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":["WAGO"]},"summary":"Attackers can modify device settings without authentication on vulnerable WAGO I/O controllers, requiring firmware updates to mitigate.","url":"https://insights.sbomify.com/CVE-2020-12506/"}
