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-2024-6873 in the wild and no public exploit code.\n\nAffected product: ClickHouse. 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-2024-6873/ (Markdown: https://insights.sbomify.com/CVE-2024-6873/index.md)","id":"CVE-2024-6873","markdown":"https://insights.sbomify.com/CVE-2024-6873/index.md","name":"CVE-2024-6873","record":{"aliases":["GHSA-432f-r822-j66f","UBUNTU-CVE-2024-6873"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ClickHouse database","requires_auth":"none","summary":"Unauthenticated attackers can trigger memory corruption in ClickHouse via crafted requests, potentially causing crashes or limited code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ClickHouse","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"It is possible to crash or redirect the execution flow of the ClickHouse server process from an unauthenticated vector by sending a specially crafted request to the ClickHouse server native interface.
