An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-20254 in the wild and no public exploit code.\n\nAffected product: Cisco SD-WAN vManage. 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-2023-20254/ (Markdown: https://insights.sbomify.com/CVE-2023-20254/index.md)","id":"CVE-2023-20254","markdown":"https://insights.sbomify.com/CVE-2023-20254/index.md","name":"CVE-2023-20254","record":{"aliases":["GHSA-r23j-cqq2-w2h2"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco SD-WAN Manager","requires_auth":"high_privilege","summary":"Authenticated attackers can access other tenants' data, modify configurations, or cause denial of service in Cisco Catalyst SD-WAN Manager when multi-tenancy is enabled.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"sd-wan_manager","vendor":"cisco"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"A vulnerability in the session management system of the Cisco Catalyst SD-WAN Manager multi-tenant feature could allow an authenticated, remote attacker to access another tenant that is being managed by the same Cisco Catalyst SD-WAN Manager instance.
