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-2017-5387 in the wild and no public exploit code.\n\nAffected product: Mozilla Firefox. 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-2017-5387/ (Markdown: https://insights.sbomify.com/CVE-2017-5387/index.md)","id":"CVE-2017-5387","markdown":"https://insights.sbomify.com/CVE-2017-5387/index.md","name":"CVE-2017-5387","record":{"aliases":["GHSA-fgxx-ch38-43gw","UBUNTU-CVE-2017-5387"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mozilla Firefox","requires_auth":"low_privilege","summary":"Attackers can determine the existence of local files by exploiting double onerror events in Firefox track tags.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mozilla","cpe":[{"product":"firefox","vendor":"mozilla"}],"cvss":{"score":3.3,"severity":"low","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-538","name":"Insertion of Sensitive Information into Externally-Accessible File or Directory"}],"description":"The existence of a specifically requested local file can be found due to the double firing of the \"onerror\" when the \"source\" attribute on a \"\u003ctrack\u003e\" tag refers to a file that does not exist if the source page is loaded locally.
