Ichiran App for iOS and Ichiran App for Android, published on 13 Feb 2023. 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-2023-22367 in the wild and no public exploit code.\n\nAffected product: Betrend Corporation and ICHIRAN INC. Ichiran App for iOS and Ichiran 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-2023-22367/ (Markdown: https://insights.sbomify.com/CVE-2023-22367/index.md)","id":"CVE-2023-22367","markdown":"https://insights.sbomify.com/CVE-2023-22367/index.md","name":"CVE-2023-22367","record":{"aliases":["GHSA-g9vx-qcqw-wcpx"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Ichiran mobile app","requires_auth":"none","summary":"Attackers can intercept encrypted traffic via man-in-the-middle attacks due to improper certificate validation in the Ichiran mobile app.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"ichiran","vendor":"ichiranusa"}],"cvss":{"score":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Ichiran App for iOS versions prior to 3.1.0 and Ichiran App for Android versions prior to 3.1.0 improperly verify server certificates, which may allow a remote unauthenticated attacker to eavesdrop on an encrypted communication via a man-in-the-middle attack.","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":"Weak cryptography in Ichiran App for iOS and Ichiran App for Android","id":"CVE-2023-22367","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Privilege escalation in ELECOM Camera Assistant and QuickFileDealer","id":"CVE-2023-22368"},"packages":[],"prev":{"headline":"Null dereference in CX-Motion-MCH","id":"CVE-2023-22366"},"products":["Ichiran App for iOS and Ichiran App for Android"],"published":"2023-02-13","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":"2025-03-21","vendors":["Betrend Corporation and ICHIRAN INC."]},"summary":"Attackers can intercept encrypted traffic via man-in-the-middle attacks due to improper certificate validation in the Ichiran mobile app.","url":"https://insights.sbomify.com/CVE-2023-22367/"}
