An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3308 in the wild and no public exploit code.\n\nAffected product: Cisco Secure Firewall Management Center. 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-2020-3308/ (Markdown: https://insights.sbomify.com/CVE-2020-3308/index.md)","id":"CVE-2020-3308","markdown":"https://insights.sbomify.com/CVE-2020-3308/index.md","name":"CVE-2020-3308","record":{"aliases":["GHSA-88c7-xpjh-3f4j"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco FTD software","requires_auth":"high_privilege","summary":"Authenticated administrators can bypass signature verification to install malicious patches on Cisco Firepower Threat Defense devices, enabling code execution.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"secure_firewall_management_center","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"A vulnerability in the Image Signature Verification feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker with administrator-level credentials to install a malicious software patch on an affected device.
