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-2021-3845 in the wild and no public exploit code.\n\nAffected product: netristv/ws-scrcpy. 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-2021-3845/ (Markdown: https://insights.sbomify.com/CVE-2021-3845/index.md)","id":"CVE-2021-3845","markdown":"https://insights.sbomify.com/CVE-2021-3845/index.md","name":"CVE-2021-3845","record":{"aliases":["GHSA-rrcw-m6cc-w2cx"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"ws-scrcpy web app","requires_auth":"none","summary":"Attackers can manipulate file paths to read or modify arbitrary files in the ws-scrcpy web application.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"ws_scrcpy","vendor":"ws_scrcpy_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-610","name":"Externally Controlled Reference to a Resource in Another Sphere"},{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"ws-scrcpy is vulnerable to External Control of File Name or Path","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"External Control of File Name or Path in netristv/ws-scrcpy","id":"CVE-2021-3845","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Unrestricted Upload of File with Dangerous Type in firefly-iii/firefly-iii","id":"CVE-2021-3846"},"packages":[],"prev":{"headline":"Rapid7 InsightVM Insufficient Session Expiration","id":"CVE-2021-3844"},"products":["netristv/ws-scrcpy"],"published":"2022-01-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["netristv"]},"summary":"Attackers can manipulate file paths to read or modify arbitrary files in the ws-scrcpy web application.","url":"https://insights.sbomify.com/CVE-2021-3845/"}
