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-2017-12300 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-2017-12300/ (Markdown: https://insights.sbomify.com/CVE-2017-12300/index.md)","id":"CVE-2017-12300","markdown":"https://insights.sbomify.com/CVE-2017-12300/index.md","name":"CVE-2017-12300","record":{"aliases":["GHSA-v68r-xxfh-w776"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco Firepower System","requires_auth":"none","summary":"An unauthenticated remote attacker can bypass SMB2 blocking policies in Cisco Firepower by sending crafted requests, requiring specific file policy configurations.","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"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the SNORT detection engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker to bypass a file policy that is configured to block the Server Message Block Version 2 (SMB2) protocol. The vulnerability is due to the incorrect detection of an SMB2 file when the detection is based on the length of the file. An attacker could exploit this vulnerability by sending a crafted SMB2 transfer request through the targeted device. A successful exploit could allow the attacker to bypass filters that are configured to block SMB2 traffic.
