An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2017-12373 exists.\n\nAffected product: Cisco legacy ASA 5500 products TLS protocol implementation. 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-2017-12373/ (Markdown: https://insights.sbomify.com/CVE-2017-12373/index.md)","id":"CVE-2017-12373","markdown":"https://insights.sbomify.com/CVE-2017-12373/index.md","name":"CVE-2017-12373","record":{"aliases":["GHSA-3q2f-qcg5-6425"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco ASA firewall","requires_auth":"none","summary":"Remote attackers can decrypt captured TLS sessions on legacy Cisco ASA devices via a Bleichenbacher oracle attack, exposing sensitive data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"adaptive_security_appliance_5505_firmware","vendor":"cisco"},{"product":"adaptive_security_appliance_5510_firmware","vendor":"cisco"},{"product":"adaptive_security_appliance_5520_firmware","vendor":"cisco"},{"product":"adaptive_security_appliance_5540_firmware","vendor":"cisco"},{"product":"adaptive_security_appliance_5550_firmware","vendor":"cisco"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"A vulnerability in the TLS protocol implementation of legacy Cisco ASA 5500 Series (ASA 5505, 5510, 5520, 5540, and 5550) devices could allow an unauthenticated, remote attacker to access sensitive information, aka a Return of Bleichenbacher's Oracle Threat (ROBOT) attack.
