An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3181 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-2020-3181/ (Markdown: https://insights.sbomify.com/CVE-2020-3181/index.md)","id":"CVE-2020-3181","markdown":"https://insights.sbomify.com/CVE-2020-3181/index.md","name":"CVE-2020-3181","record":{"aliases":["GHSA-76gp-2rvp-j8f4"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service","other"],"network_reachable":"yes","non_default_config":false,"product_category":"Email Security Appliance","requires_auth":"none","summary":"Unauthenticated attackers can exhaust resources via crafted emails, causing delays and potentially delivering malware to users on Cisco Email Security Appliances.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"email_security_appliance","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability in the malware detection functionality in Cisco Advanced Malware Protection (AMP) in Cisco AsyncOS Software for Cisco Email Security Appliances (ESAs) could allow an unauthenticated remote attacker to exhaust resources on an affected device.
