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-2022-20826 in the wild and no public exploit code.\n\nAffected product: Cisco Adaptive Security Appliance Software. 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-2022-20826/ (Markdown: https://insights.sbomify.com/CVE-2022-20826/index.md)","id":"CVE-2022-20826","markdown":"https://insights.sbomify.com/CVE-2022-20826/index.md","name":"CVE-2022-20826","record":{"aliases":["GHSA-wpmq-hr5x-r7wq"],"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 Secure Firewall","requires_auth":"none","summary":"An attacker with physical access can bypass secure boot to execute persistent malicious code on Cisco ASA and FTD devices.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"adaptive_security_appliance_software","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-501","name":"Trust Boundary Violation"}],"description":"A vulnerability in the secure boot implementation of Cisco Secure Firewalls 3100 Series that are running Cisco Adaptive Security Appliance (ASA) Software or Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated attacker with physical access to the device to bypass the secure boot functionality.\r\n\r This vulnerability is due to a logic error in the boot process.
