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-2023-28523 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-2023-28523/ (Markdown: https://insights.sbomify.com/CVE-2023-28523/index.md)","id":"CVE-2023-28523","markdown":"https://insights.sbomify.com/CVE-2023-28523/index.md","name":"CVE-2023-28523","record":{"aliases":["GHSA-hg8q-63q2-p669"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM Informix Database","requires_auth":"none","summary":"A heap buffer overflow in IBM Informix Dynamic Server allows attackers to execute arbitrary code via improper bounds checking.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"informix_dynamic_server","vendor":"ibm"},{"product":"informix_dynamic_server_on_cloud_pak_for_data","vendor":"ibm"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"IBM Informix Dynamic Server 12.10 and 14.10 onsmsync is vulnerable to a heap buffer overflow, caused by improper bounds checking which could allow an attacker to execute arbitrary code.
