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-2018-0518 in the wild and no public exploit code.\n\nAffected product: Linecorp Line. 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-2018-0518/ (Markdown: https://insights.sbomify.com/CVE-2018-0518/index.md)","id":"CVE-2018-0518","markdown":"https://insights.sbomify.com/CVE-2018-0518/index.md","name":"CVE-2018-0518","record":{"aliases":["GHSA-h956-h9q8-3c53"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"LINE iOS app","requires_auth":"none","summary":"Man-in-the-middle attackers can spoof servers and obtain sensitive information due to missing X.509 certificate verification in the LINE iOS app.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"line","vendor":"linecorp"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"LINE for iOS version 7.1.3 to 7.1.5 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.","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 LINE for iOS","id":"CVE-2018-0518","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linecorp:line","products":["linecorp:line"],"type":"weak_cryptography","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in FS010W","id":"CVE-2018-0519"},"packages":[],"prev":{"headline":"Privilege escalation in Anshin net security for Windows","id":"CVE-2018-0517"},"products":["LINE for iOS"],"published":"2018-02-23","related":[{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-45559","kev_date_added":null,"published":"2024-01-03"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43305","kev_date_added":null,"published":"2023-12-08"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43300","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.2,"headline":"Code injection in n/a","id":"CVE-2023-43301","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43302","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43303","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43304","kev_date_added":null,"published":"2023-12-07"}],"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":"2024-08-05","vendors":["LINE Corporation"]},"summary":"Man-in-the-middle attackers can spoof servers and obtain sensitive information due to missing X.509 certificate verification in the LINE iOS app.","url":"https://insights.sbomify.com/CVE-2018-0518/"}
