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-2024-20320 in the wild and no public exploit code.\n\nAffected product: Cisco Ios Xr. 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-2024-20320/ (Markdown: https://insights.sbomify.com/CVE-2024-20320/index.md)","id":"CVE-2024-20320","markdown":"https://insights.sbomify.com/CVE-2024-20320/index.md","name":"CVE-2024-20320","record":{"aliases":["GHSA-4hv7-4c5m-8c4c"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco IOS XR Router","requires_auth":"low_privilege","summary":"A local attacker with low privileges can elevate to root on Cisco IOS XR routers by exploiting insufficient validation in the SSH client CLI command.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios_xr","vendor":"cisco"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-266","name":"Incorrect Privilege Assignment"}],"description":"A vulnerability in the SSH client feature of Cisco IOS XR Software for Cisco 8000 Series Routers and Cisco Network Convergence System (NCS) 540 Series and 5700 Series Routers could allow an authenticated, local attacker to elevate privileges on an affected device. \r\n\r This vulnerability is due to insufficient validation of arguments that are included with the SSH client CLI command.
