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-2023-20071 in the wild and no public exploit code.\n\nAffected product: Cisco Secure Firewall Threat Defense. 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-2023-20071/ (Markdown: https://insights.sbomify.com/CVE-2023-20071/index.md)","id":"CVE-2023-20071","markdown":"https://insights.sbomify.com/CVE-2023-20071/index.md","name":"CVE-2023-20071","record":{"aliases":["GHSA-54ph-4xc5-8pjx"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Snort IPS Engine","requires_auth":"none","summary":"Unauthenticated remote attackers can bypass FTP inspection policies in Cisco Snort engines by sending crafted FTP traffic, allowing malicious payload delivery.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"cyber_vision","vendor":"cisco"},{"product":"meraki_mx_security_appliance_firmware","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"},{"product":"unified_threat_defense","vendor":"cisco"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-1039","name":"Inadequate Detection or Handling of Adversarial Input Perturbations in Automated Recognition Mechanism"}],"description":"Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system.
