An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-12514 in the wild and no public exploit code.\n\nAffected product: Pepper+Fuchs Comtrol IO-Link Master. 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-2020-12514/ (Markdown: https://insights.sbomify.com/CVE-2020-12514/index.md)","id":"CVE-2020-12514","markdown":"https://insights.sbomify.com/CVE-2020-12514/index.md","name":"CVE-2020-12514","record":{"aliases":["GHSA-pvhr-37pj-qc85"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IO-Link Master","requires_auth":"high_privilege","summary":"Attackers can cause a denial of service in the discoveryd service of Pepperl+Fuchs Comtrol IO-Link Masters via a NULL pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"io-link_master_4-eip_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_4-pnio_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_8-eip-l_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_8-eip_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_8-pnio-l_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_8-pnio_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_dr-8-eip-p_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_dr-8-eip-t_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_dr-8-eip_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_dr-8-pnio-p_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_dr-8-pnio-t_firmware","vendor":"pepperl-fuchs"},{"product":"io-link_master_dr-8-pnio_firmware","vendor":"pepperl-fuchs"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Pepperl+Fuchs Comtrol IO-Link Master in Version 1.5.48 and below is prone to a NULL Pointer Dereference that leads to a DoS in discoveryd","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":"Pepper+Fuchs Comtrol IO-Link Master NULL Pointer Dereference","id":"CVE-2020-12514","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-12515"},"packages":[],"prev":{"headline":"Pepper+Fuchs Comtrol IO-Link Master OS Command Injection","id":"CVE-2020-12513"},"products":["Comtrol IO-Link Master"],"published":"2021-01-22","related":[{"cvss_score":8.8,"headline":"Pepper+Fuchs Comtrol IO-Link Master Cross-Site Request Forgery","id":"CVE-2020-12511","kev_date_added":null,"published":"2021-01-22"},{"cvss_score":7.5,"headline":"Pepper+Fuchs Comtrol IO-Link Master Cross-Site Scripting","id":"CVE-2020-12512","kev_date_added":null,"published":"2021-01-22"},{"cvss_score":7.5,"headline":"Pepper+Fuchs Comtrol IO-Link Master OS Command Injection","id":"CVE-2020-12513","kev_date_added":null,"published":"2021-01-22"}],"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":["Pepper+Fuchs"]},"summary":"Attackers can cause a denial of service in the discoveryd service of Pepperl+Fuchs Comtrol IO-Link Masters via a NULL pointer dereference.","url":"https://insights.sbomify.com/CVE-2020-12514/"}
