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-2021-45773 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-2021-45773/ (Markdown: https://insights.sbomify.com/CVE-2021-45773/index.md)","id":"CVE-2021-45773","markdown":"https://insights.sbomify.com/CVE-2021-45773/index.md","name":"CVE-2021-45773","record":{"aliases":["GHSA-qh39-hpr9-w6qx"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IEC 60870 library","requires_auth":"none","summary":"A NULL pointer dereference in the lib60870 library allows attackers to cause a segmentation fault and application crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lib60870","vendor":"mz-automation"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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-476","name":"NULL Pointer Dereference"}],"description":"A NULL pointer dereference in CS104_IPAddress_setFromString at src/iec60870/cs104/cs104_slave.c of lib60870 commit 0d5e76e can lead to a segmentation fault or application crash.","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":"Null dereference in n/a","id":"CVE-2021-45773","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2021-45774"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2021-45769"},"products":["n/a"],"published":"2022-01-14","related":[{"cvss_score":7.5,"headline":"Denial of service in MZ Automation\"","id":"CVE-2021-21778","kev_date_added":null,"published":"2021-08-25"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2019-6137","kev_date_added":null,"published":"2019-01-11"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2023-23205","kev_date_added":null,"published":"2023-02-24"}],"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":"A NULL pointer dereference in the lib60870 library allows attackers to cause a segmentation fault and application crash.","url":"https://insights.sbomify.com/CVE-2021-45773/"}
