It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-43383 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Lucene.Net.Replicator (NuGet): affected from 4.8.0-beta00005; fixed in 4.8.0-beta00017\n- Lucene.Net.Replicator (NuGet): affected from 4.8.0-beta00005; fixed in 4.8.0-beta00017\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-2024-43383/ (Markdown: https://insights.sbomify.com/CVE-2024-43383/index.md)","id":"CVE-2024-43383","markdown":"https://insights.sbomify.com/CVE-2024-43383/index.md","name":"CVE-2024-43383","record":{"aliases":["GHSA-2qw8-ppr5-m96c"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lucene.NET Replicator library","requires_auth":"low_privilege","summary":"An attacker can achieve remote code execution by intercepting replication traffic and sending malicious JSON payloads to the Lucene.NET Replicator library.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"lucene.net","vendor":"apache"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of Untrusted Data vulnerability in Apache Lucene.Net.Replicator.\n\nThis issue affects Apache Lucene.NET's Replicator library: from 4.8.0-beta00005 through 4.8.0-beta00016.\n\nAn attacker that can intercept traffic between a replication client and server, or control the target replication node URL, can provide a specially-crafted JSON response that is deserialized as an attacker-provided exception type.
