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-2025-20181 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-2025-20181/ (Markdown: https://insights.sbomify.com/CVE-2025-20181/index.md)","id":"CVE-2025-20181","markdown":"https://insights.sbomify.com/CVE-2025-20181/index.md","name":"CVE-2025-20181","record":{"aliases":["GHSA-95h6-vgwg-qcqc"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco IOS Switch","requires_auth":"none","summary":"An attacker with local access or physical presence can bypass boot signature verification to execute persistent arbitrary code on Cisco Catalyst switches.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios","vendor":"cisco"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"A vulnerability in Cisco IOS Software for Cisco Catalyst 2960X, 2960XR, 2960CX, and 3560CX Series Switches could allow an authenticated, local attacker with privilege level 15 or an unauthenticated attacker with physical access to the device to execute persistent code at boot time and break the chain of trust.\r\n\r This vulnerability is due to missing signature verification for specific files that may be loaded during the device boot process.
