An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-2451 in the wild and no public exploit code.\n\nAffected product: SAP HANA Extended Application Services. 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-2018-2451/ (Markdown: https://insights.sbomify.com/CVE-2018-2451/index.md)","id":"CVE-2018-2451","markdown":"https://insights.sbomify.com/CVE-2018-2451/index.md","name":"CVE-2018-2451","record":{"aliases":["GHSA-w5mg-8gpq-pmwq"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP HANA XS","requires_auth":"high_privilege","summary":"Attackers can reuse expired CLI session tokens to access resources after authorization revocation, requiring SAP HANA XS administrators to apply security patches.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"hana_extended_application_services","vendor":"sap"}],"cvss":{"score":6.6,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"XS Command-Line Interface (CLI) user sessions with the SAP HANA Extended Application Services (XS), version 1, advanced server may have an unintentional prolonged period of validity.
