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-2020-3343 in the wild and no public exploit code.\n\nAffected product: Cisco AMP for Endpoints. 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-2020-3343/ (Markdown: https://insights.sbomify.com/CVE-2020-3343/index.md)","id":"CVE-2020-3343","markdown":"https://insights.sbomify.com/CVE-2020-3343/index.md","name":"CVE-2020-3343","record":{"aliases":["GHSA-fmpm-2fhr-jw4j"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco AMP for Endpoints","requires_auth":"low_privilege","summary":"A local authenticated attacker can cause a buffer overflow in Cisco AMP for Endpoints, leading to a service crash and restart.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"advanced_malware_protection_for_endpoints","vendor":"cisco"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability in Cisco AMP for Endpoints Linux Connector Software and Cisco AMP for Endpoints Mac Connector Software could allow an authenticated, local attacker to cause a buffer overflow on an affected device.
