It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-4839 in the wild and no public exploit code.\n\nAffected product: Money Forward. 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-2016-4839/ (Markdown: https://insights.sbomify.com/CVE-2016-4839/index.md)","id":"CVE-2016-4839","markdown":"https://insights.sbomify.com/CVE-2016-4839/index.md","name":"CVE-2016-4839","record":{"aliases":["GHSA-h25f-2g8f-4527"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Money Forward Android apps","requires_auth":"none","summary":"Attackers can disclose device-stored information via a crafted app due to improper WebView implementation in Money Forward Android applications.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"money_forward_for_apppass","vendor":"moneyforward"},{"product":"money_forward_for_au_smartpass","vendor":"moneyforward"},{"product":"money_forward_for_chou_houdai","vendor":"moneyforward"},{"product":"money_forward_for_sbi_sumishin_net_bank","vendor":"moneyforward"},{"product":"money_forward_for_shiga_bank","vendor":"moneyforward"},{"product":"money_forward_for_shizuoka_bank","vendor":"moneyforward"},{"product":"money_forward_for_the_gunma_bank","vendor":"moneyforward"},{"product":"money_forward_for_the_toho_bank","vendor":"moneyforward"},{"product":"money_forward_for_tokai_tokyo_securities","vendor":"moneyforward"},{"product":"money_forward_for_ymfg","vendor":"moneyforward"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Android Apps Money Forward (prior to v7.18.0), Money Forward for The Gunma Bank (prior to v1.2.0), Money Forward for SHIGA BANK (prior to v1.2.0), Money Forward for SHIZUOKA BANK (prior to v1.4.0), Money Forward for SBI Sumishin Net Bank (prior to v1.6.0), Money Forward for Tokai Tokyo Securities (prior to v1.4.0), Money Forward for THE TOHO BANK (prior to v1.3.0), Money Forward for YMFG (prior to v1.5.0) provided by Money Forward, Inc. and Money Forward for AppPass (prior to v7.18.3), Money Forward for au SMARTPASS (prior to v7.18.0), Money Forward for Chou Houdai (prior to v7.18.3) provided by SOURCENEXT CORPORATION do not properly implement the WebView class, which allows an attacker to disclose information stored on the device via a specially crafted application.","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":"Information disclosure in Money Forward","id":"CVE-2016-4839","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2016"},"n_packages":0,"n_references":4,"next":{"headline":"Weak cryptography in n/a","id":"CVE-2016-4840"},"packages":[],"prev":{"headline":"Other in Money Forward","id":"CVE-2016-4838"},"products":["Money Forward","Money Forward for AppPass","Money Forward for Chou Houdai","Money Forward for SBI Sumishin Net Bank","Money Forward for SHIGA BANK","Money Forward for SHIZUOKA BANK","Money Forward for THE TOHO BANK","Money Forward for The Gunma Bank","Money Forward for Tokai Tokyo Securities","Money Forward for YMFG","Money Forward for au SMARTPASS"],"published":"2017-05-12","related":[{"cvss_score":7.8,"headline":"Other in Money Forward","id":"CVE-2016-4838","kev_date_added":null,"published":"2017-05-12"}],"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":"2024-08-06","vendors":["Money Foward, Inc.","SOURCENEXT CORPORATION"]},"summary":"Attackers can disclose device-stored information via a crafted app due to improper WebView implementation in Money Forward Android applications.","url":"https://insights.sbomify.com/CVE-2016-4839/"}
