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-2020-3204 in the wild and no public exploit code.\n\nAffected product: Cisco Ios. 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-2020-3204/ (Markdown: https://insights.sbomify.com/CVE-2020-3204/index.md)","id":"CVE-2020-3204","markdown":"https://insights.sbomify.com/CVE-2020-3204/index.md","name":"CVE-2020-3204","record":{"aliases":["GHSA-4273-vg8f-3qj2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco IOS","requires_auth":"high_privilege","summary":"Authenticated local attackers with privileged EXEC access can execute arbitrary code with root privileges via malicious Tcl scripts in Cisco IOS.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios","vendor":"cisco"},{"product":"ios_xe","vendor":"cisco"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the Tool Command Language (Tcl) interpreter of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, local attacker with privileged EXEC credentials to execute arbitrary code on the underlying operating system (OS) with root privileges.
