Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-3943 in the wild and no public exploit code.\n\nAffected product: Mikrotik Routeros. 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-2019-3943/ (Markdown: https://insights.sbomify.com/CVE-2019-3943/index.md)","id":"CVE-2019-3943","markdown":"https://insights.sbomify.com/CVE-2019-3943/index.md","name":"CVE-2019-3943","record":{"aliases":["GHSA-5qg2-wqx5-pq26"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"MikroTik RouterOS","requires_auth":"low_privilege","summary":"Authenticated attackers can traverse directories to read and write files outside the sandbox via HTTP or Winbox interfaces.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"routeros","vendor":"mikrotik"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"MikroTik RouterOS versions Stable 6.43.12 and below, Long-term 6.42.12 and below, and Testing 6.44beta75 and below are vulnerable to an authenticated, remote directory traversal via the HTTP or Winbox interfaces.
