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-2016-4842 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2016-4842/ (Markdown: https://insights.sbomify.com/CVE-2016-4842/index.md)","id":"CVE-2016-4842","markdown":"https://insights.sbomify.com/CVE-2016-4842/index.md","name":"CVE-2016-4842","record":{"aliases":["GHSA-958x-6cr2-9366"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cybozu Mailwise","requires_auth":"none","summary":"Remote attackers can obtain information on when an email is read in Cybozu Mailwise, compromising user privacy.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"mailwise","vendor":"cybozu"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Cybozu Mailwise before 5.4.0 allows remote attackers to obtain information on when an email is read.","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 n/a","id":"CVE-2016-4842","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":"Information disclosure in n/a","id":"CVE-2016-4843"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2016-4841"},"products":["n/a"],"published":"2017-04-20","related":[{"cvss_score":7.5,"headline":"Path traversal in Cybozu Mailwise","id":"CVE-2018-0702","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":6.5,"headline":"Information disclosure in n/a","id":"CVE-2016-4843","kev_date_added":null,"published":"2017-04-20"},{"cvss_score":6.1,"headline":"Cross-site scripting in Cybozu Mailwise","id":"CVE-2018-0557","kev_date_added":null,"published":"2018-06-26"},{"cvss_score":6.1,"headline":"Cross-site scripting in Cybozu Mailwise","id":"CVE-2018-0558","kev_date_added":null,"published":"2018-06-26"},{"cvss_score":6.1,"headline":"Cross-site scripting in Cybozu Mailwise","id":"CVE-2018-0559","kev_date_added":null,"published":"2018-06-26"},{"cvss_score":4.6,"headline":"Information disclosure in Android App 'Mailwise for Android'","id":"CVE-2020-5572","kev_date_added":null,"published":"2020-05-29"},{"cvss_score":4.3,"headline":"Other in n/a","id":"CVE-2016-4841","kev_date_added":null,"published":"2017-04-21"}],"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":["n/a"]},"summary":"Remote attackers can obtain information on when an email is read in Cybozu Mailwise, compromising user privacy.","url":"https://insights.sbomify.com/CVE-2016-4842/"}
