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-2020-12141 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-12141/ (Markdown: https://insights.sbomify.com/CVE-2020-12141/index.md)","id":"CVE-2020-12141","markdown":"https://insights.sbomify.com/CVE-2020-12141/index.md","name":"CVE-2020-12141","record":{"aliases":["GHSA-jxvq-67hx-ghg3"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Contiki-NG OS","requires_auth":"none","summary":"An out-of-bounds read in the SNMP stack allows attackers to cause denial of service and potentially disclose information via crafted packets.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"contiki-ng","vendor":"contiki-ng"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"An out-of-bounds read in the SNMP stack in Contiki-NG 4.4 and earlier allows an attacker to cause a denial of service and potentially disclose information via crafted SNMP packets to snmp_ber_decode_string_len_buffer in os/net/app-layer/snmp/snmp-ber.c.","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":"Information disclosure in n/a","id":"CVE-2020-12141","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"IPSec UDP key material can be retrieved from EdgeConnect by a user with admin credentials","id":"CVE-2020-12142"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-12140"},"products":["n/a"],"published":"2021-10-19","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2018-19417","kev_date_added":null,"published":"2018-11-21"},{"cvss_score":9.8,"headline":"Contiki-NG has off-by-one error in Antelope DBMS","id":"CVE-2023-30546","kev_date_added":null,"published":"2023-04-26"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-24336","kev_date_added":null,"published":"2020-12-11"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14934","kev_date_added":null,"published":"2020-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14935","kev_date_added":null,"published":"2020-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14936","kev_date_added":null,"published":"2020-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-8359","kev_date_added":null,"published":"2020-04-23"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"An out-of-bounds read in the SNMP stack allows attackers to cause denial of service and potentially disclose information via crafted packets.","url":"https://insights.sbomify.com/CVE-2020-12141/"}
