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-2017-16778 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2017-16778/ (Markdown: https://insights.sbomify.com/CVE-2017-16778/index.md)","id":"CVE-2017-16778","markdown":"https://insights.sbomify.com/CVE-2017-16778/index.md","name":"CVE-2017-16778","record":{"aliases":["GHSA-54w4-4qgr-936w"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Fermax Outdoor Panel","requires_auth":"none","summary":"Physical attackers can inject DTMF tones to bypass access controls and gain unauthorized entry to restricted floors.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"outdoor_panel_firmware","vendor":"fermax"}],"cvss":{"score":4.6,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"An access control weakness in the DTMF tone receiver of Fermax Outdoor Panel allows physical attackers to inject a Dual-Tone-Multi-Frequency (DTMF) tone to invoke an access grant that would allow physical access to a restricted floor/level.

However, due to incorrect access control, an attacker could inject it via the speaker unit to perform an access grant to gain unauthorized access, as demonstrated by a loud DTMF tone representing '1' and a long '#' (697 Hz and 1209 Hz, followed by 941 Hz and 1477 Hz).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2019-12-20","github_poc":1,"max_poc_stars":22,"metasploit":0,"nuclei":0,"refs":[{"date":"2019-12-20T07:20:50Z","kind":"github_poc","ref":"https://github.com/breaktoprotect/CVE-2017-16778-Intercom-DTMF-Injection","stars":22,"title":"A coordinated disclosure and security advisory on Fermax Intercom DTML Injection vulneraiblity.
