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-2022-2973 in the wild and no public exploit code.\n\nAffected product: MZ Automation libIEC61850. 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-2022-2973/ (Markdown: https://insights.sbomify.com/CVE-2022-2973/index.md)","id":"CVE-2022-2973","markdown":"https://insights.sbomify.com/CVE-2022-2973/index.md","name":"CVE-2022-2973","record":{"aliases":["GHSA-8cpp-2498-rv3h"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IEC 61850 library","requires_auth":"none","summary":"An attacker can crash the server by triggering a NULL pointer dereference in the libIEC61850 library.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"libiec61850","vendor":"mz-automation"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"MZ Automation's libIEC61850 (versions 1.4 and prior; version 1.5 prior to commit a3b04b7bc4872a5a39e5de3fdc5fbde52c09e10e) uses a NULL pointer in certain situations. which could allow an attacker to crash the server.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"MZ Automation libIEC61850 NULL Pointer Dereference","id":"CVE-2022-2973","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Avaya Aura Application Enablement Services weak permissions in web application","id":"CVE-2022-2975"},"packages":[],"prev":{"headline":"MZ Automation libIEC61850 Stack-Based Buffer Overflow","id":"CVE-2022-2972"},"products":["libIEC61850"],"published":"2022-09-23","related":[{"cvss_score":10,"headline":"MZ Automation libIEC61850 Stack-Based Buffer Overflow","id":"CVE-2022-2970","kev_date_added":null,"published":"2022-09-23"},{"cvss_score":10,"headline":"MZ Automation libIEC61850 Stack-Based Buffer Overflow","id":"CVE-2022-2972","kev_date_added":null,"published":"2022-09-23"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-45970","kev_date_added":null,"published":"2024-11-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-45971","kev_date_added":null,"published":"2024-11-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-19185","kev_date_added":null,"published":"2018-11-12"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-18957","kev_date_added":null,"published":"2018-11-05"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-18834","kev_date_added":null,"published":"2018-10-30"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-16","vendors":["MZ Automation"]},"summary":"An attacker can crash the server by triggering a NULL pointer dereference in the libIEC61850 library.","url":"https://insights.sbomify.com/CVE-2022-2973/"}
