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-2023-20075 in the wild and no public exploit code.\n\nAffected product: Cisco Email Security Appliance. 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-2023-20075/ (Markdown: https://insights.sbomify.com/CVE-2023-20075/index.md)","id":"CVE-2023-20075","markdown":"https://insights.sbomify.com/CVE-2023-20075/index.md","name":"CVE-2023-20075","record":{"aliases":["GHSA-vwv2-hg2h-447m"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco Secure Email Gateway","requires_auth":"high_privilege","summary":"Authenticated administrators can inject OS commands into the CLI to escape restricted prompts and execute arbitrary code on the underlying system.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"email_security_appliance","vendor":"cisco"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"Vulnerability in the CLI of Cisco Secure Email Gateway could allow an authenticated, remote attacker to execute arbitrary commands.\r\n\r These vulnerability is due to improper input validation in the CLI.
