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-2018-1636 in the wild and no public exploit code.\n\nAffected product: Ibm Informix Dynamic Server. 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-2018-1636/ (Markdown: https://insights.sbomify.com/CVE-2018-1636/index.md)","id":"CVE-2018-1636","markdown":"https://insights.sbomify.com/CVE-2018-1636/index.md","name":"CVE-2018-1636","record":{"aliases":["GHSA-7j5j-7jpv-gf26"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM Informix Database","requires_auth":"high_privilege","summary":"An authenticated user can exploit a stack-based buffer overflow in IBM Informix to execute code with root privileges, leading to full system compromise.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"informix_dynamic_server","vendor":"ibm"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.0/AC:L/UI:N/S:C/PR:H/C:H/I:H/A:H/AV:L/E:U/RC:C/RL:O","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Stack-based buffer overflow in oninit in IBM Informix Dynamic Server Enterprise Edition 12.1 allows an authenticated user to execute predefined code with root privileges, such as escalating to a root shell.
