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-2021-34581 in the wild and no public exploit code.\n\nAffected product: WAGO 750-831/xxx-xxx, 750-880/xxx-xxx, 750-881, 750-889. 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-2021-34581/ (Markdown: https://insights.sbomify.com/CVE-2021-34581/index.md)","id":"CVE-2021-34581","markdown":"https://insights.sbomify.com/CVE-2021-34581/index.md","name":"CVE-2021-34581","record":{"aliases":["GHSA-v448-m2g5-fm7c"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WAGO I/O controller","requires_auth":"none","summary":"An unauthenticated attacker can cause a denial of service on WAGO I/O controllers due to a resource management flaw in the OpenSSL implementation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"750-831\\/000-002_firmware","vendor":"wago"},{"product":"750-831_firmware","vendor":"wago"},{"product":"750-880\\/025-000_firmware","vendor":"wago"},{"product":"750-880\\/025-001_firmware","vendor":"wago"},{"product":"750-880\\/025-002_firmware","vendor":"wago"},{"product":"750-880\\/040-000_firmware","vendor":"wago"},{"product":"750-880_firmware","vendor":"wago"},{"product":"750-881_firmware","vendor":"wago"},{"product":"750-889_firmware","vendor":"wago"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-772","name":"Missing Release of Resource after Effective Lifetime"}],"description":"Missing Release of Resource after Effective Lifetime vulnerability in OpenSSL implementation of WAGO 750-831/xxx-xxx, 750-880/xxx-xxx, 750-881, 750-889 in versions FW4 up to FW15 allows an unauthenticated attacker to cause DoS on the device.","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: Denial of Service vulnerability inside the OpenSSL implementation","id":"CVE-2021-34581","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Phoenix Contact: FL MGUARD XSS through web-based management and REST API","id":"CVE-2021-34582"},"packages":[],"prev":{"headline":"Remote user enumeration in mymbCONNECT24, mbCONNECT24 \u003c= 2.9.0","id":"CVE-2021-34580"},"products":["750-831/xxx-xxx, 750-880/xxx-xxx, 750-881, 750-889"],"published":"2021-08-31","related":[],"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":"An unauthenticated attacker can cause a denial of service on WAGO I/O controllers due to a resource management flaw in the OpenSSL implementation.","url":"https://insights.sbomify.com/CVE-2021-34581/"}
