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-2020-1964 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.heron:heron-simulator (Maven): affected from 0.20.0-incubating; fixed in 0.20.3-incubating\n- org.apache.heron:heron-simulator (Maven): affected from 0.20.0-incubating; fixed in 0.20.3-incubating\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-2020-1964/ (Markdown: https://insights.sbomify.com/CVE-2020-1964/index.md)","id":"CVE-2020-1964","markdown":"https://insights.sbomify.com/CVE-2020-1964/index.md","name":"CVE-2020-1964","record":{"aliases":["GHSA-hjgm-f7vx-m5g7"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Heron","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by exploiting unsafe YAML deserialization in Apache Heron.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"heron","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"It was noticed that Apache Heron 0.20.2-incubating, Release 0.20.1-incubating, and Release v-0.20.0-incubating does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerabilities (CWE-502: Deserialization of Untrusted Data).","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Deserialization of Untrusted Data in Apache Heron","id":"CVE-2020-1964","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2020"},"n_packages":2,"n_references":5,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-1966"},"packages":[{"ecosystem":"Maven","fixed":["0.20.3-incubating"],"introduced":["0.20.0-incubating"],"last_affected":[],"package":"org.apache.heron:heron-simulator","purl":null,"source":"GHSA-hjgm-f7vx-m5g7"},{"ecosystem":"Maven","fixed":["0.20.3-incubating"],"introduced":["0.20.0-incubating"],"last_affected":[],"package":"org.apache.heron:heron-simulator","purl":"pkg:maven/org.apache.heron/heron-simulator","source":"GHSA-hjgm-f7vx-m5g7"}],"prev":{"headline":"File system access via H2 in Apache Ignite","id":"CVE-2020-1963"},"products":["Apache Heron"],"published":"2020-04-16","related":[{"cvss_score":9.8,"headline":"CRLF log injection","id":"CVE-2021-42010","kev_date_added":null,"published":"2022-10-24"},{"cvss_score":7.5,"headline":"Path traversal in Apache Incubator Heron","id":"CVE-2018-11789","kev_date_added":null,"published":"2019-03-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"Remote attackers can execute arbitrary code by exploiting unsafe YAML deserialization in Apache Heron.","url":"https://insights.sbomify.com/CVE-2020-1964/"}
