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-2023-21830 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- java (Bitnami): affected all versions; fixed in 1.8.0, 8.0.361\n- java-min (Bitnami): affected all versions; fixed in 1.8.0, 8.0.361\n- jre (Bitnami): affected all versions; fixed in 1.8.0, 8.0.361\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-2023-21830/ (Markdown: https://insights.sbomify.com/CVE-2023-21830/index.md)","id":"CVE-2023-21830","markdown":"https://insights.sbomify.com/CVE-2023-21830/index.md","name":"CVE-2023-21830","record":{"aliases":["BIT-java-2023-21830","BIT-java-min-2023-21830","BIT-jre-2023-21830","CLEANSTART-2026-LG84885","DEBIAN-CVE-2023-21830","GHSA-xw85-qpwr-ch8h","MINI-32vj-96cm-6pcw","MINI-5gv5-44cf-6278","MINI-g5j5-jvq6-h5v6","MINI-rqj3-rxqw-52gm","UBUNTU-CVE-2023-21830","openSUSE-SU-2024:12756-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Java SE Runtime","requires_auth":"none","summary":"Unauthenticated attackers can modify data in Java SE and GraalVM via a deserialization flaw in sandboxed client environments.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"zulu","vendor":"azul"},{"product":"communications_unified_assurance","vendor":"oracle"},{"product":"graalvm","vendor":"oracle"},{"product":"jdk","vendor":"oracle"},{"product":"jre","vendor":"oracle"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[],"description":"Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Serialization).  Supported versions that are affected are Oracle Java SE: 8u351, 8u351-perf; Oracle GraalVM Enterprise Edition: 20.3.8 and  21.3.4. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition.  Successful attacks of this vulnerability can result in  unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data.
