An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-39507 in the wild and no public exploit code.\n\nAffected product: Recruit Co., Ltd. \"Rikunabi NEXT\" App for Android. 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-2023-39507/ (Markdown: https://insights.sbomify.com/CVE-2023-39507/index.md)","id":"CVE-2023-39507","markdown":"https://insights.sbomify.com/CVE-2023-39507/index.md","name":"CVE-2023-39507","record":{"aliases":["GHSA-96qx-whg9-w5rw"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Android job search app","requires_auth":"none","summary":"A malicious intent can bypass authorization in the URL scheme handler, allowing access to arbitrary websites within the Rikunabi NEXT Android app.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"rikunabi_next","vendor":"recruit"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Improper authorization in the custom URL scheme handler in \"Rikunabi NEXT\" App for Android prior to ver. 11.5.0 allows a malicious intent to lead the vulnerable App to access an arbitrary website.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in \"Rikunabi NEXT\" App for Android","id":"CVE-2023-39507","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Airflow: Airflow \"Run task\" feature allows execution with unnecessary priviledges","id":"CVE-2023-39508"},"packages":[],"prev":{"headline":"PDF-XChange Editor createDataObject Directory Traversal Remote Code Execution Vulnerability","id":"CVE-2023-39506"},"products":["\"Rikunabi NEXT\" App for Android"],"published":"2023-08-16","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-08","vendors":["Recruit Co., Ltd."]},"summary":"A malicious intent can bypass authorization in the URL scheme handler, allowing access to arbitrary websites within the Rikunabi NEXT Android app.","url":"https://insights.sbomify.com/CVE-2023-39507/"}
