An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-27491 and fix it if it is affected.\n\nWhat it is: CVE-2021-27491 is a high-severity vulnerability in Ypsomed mylife Cloud, mylife Mobile Application, published on 30 Jul 2021. 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-2021-27491 in the wild and no public exploit code.\n\nAffected product: Ypsomed mylife Cloud, mylife Mobile Application. 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-2021-27491/ (Markdown: https://insights.sbomify.com/CVE-2021-27491/index.md)","id":"CVE-2021-27491","markdown":"https://insights.sbomify.com/CVE-2021-27491/index.md","name":"CVE-2021-27491","record":{"aliases":["GHSA-vggc-4gwq-rq7x"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Ypsomed mylife App","requires_auth":"none","summary":"The Ypsomed mylife Cloud and mobile app disclose password hashes during registration, allowing attackers to potentially compromise user accounts.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"mylife","vendor":"ypsomed"},{"product":"mylife_cloud","vendor":"ypsomed"}],"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-522","name":"Insufficiently Protected Credentials"}],"description":"Ypsomed mylife Cloud, mylife Mobile Application:Ypsomed mylife Cloud,All versions prior to 1.7.2,Ypsomed mylife App,All versions prior to 1.7.5,The Ypsomed mylife Cloud discloses password hashes during the registration process.","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 Ypsomed mylife Cloud, mylife Mobile Application","id":"CVE-2021-27491","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"XML external entity in Datakit Software libraries embedded in Luxion KeyShot software","id":"CVE-2021-27492"},"packages":[],"prev":{"headline":"Memory corruption in Datakit Software libraries embedded in Luxion KeyShot software","id":"CVE-2021-27490"},"products":["Ypsomed mylife Cloud, mylife Mobile Application"],"published":"2021-07-30","related":[{"cvss_score":7.1,"headline":"Information disclosure in Ypsomed mylife Cloud, mylife Mobile Application","id":"CVE-2021-27495","kev_date_added":null,"published":"2021-07-30"},{"cvss_score":5.9,"headline":"Weak cryptography in Ypsomed mylife Cloud, mylife Mobile Application","id":"CVE-2021-27499","kev_date_added":null,"published":"2021-08-02"},{"cvss_score":4.8,"headline":"Hardcoded credentials in Ypsomed mylife Cloud, mylife Mobile Application","id":"CVE-2021-27503","kev_date_added":null,"published":"2021-08-02"}],"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":["n/a"]},"summary":"The Ypsomed mylife Cloud and mobile app disclose password hashes during registration, allowing attackers to potentially compromise user accounts.","url":"https://insights.sbomify.com/CVE-2021-27491/"}
