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-2021-42545 in the wild and no public exploit code.\n\nAffected product: Business-DNA Solutions GmbH TopEase. 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-2021-42545/ (Markdown: https://insights.sbomify.com/CVE-2021-42545/index.md)","id":"CVE-2021-42545","markdown":"https://insights.sbomify.com/CVE-2021-42545/index.md","name":"CVE-2021-42545","record":{"aliases":["GHSA-mqvw-2h8p-cf8g"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"TopEase Platform","requires_auth":"none","summary":"Remote attackers can reuse or steal user and admin sessions due to insufficient session expiration, leading to account takeover.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[{"product":"topease","vendor":"business-dnasolutions"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"An insufficient session expiration vulnerability exists in Business-DNA Solutions GmbH’s TopEase® Platform Version \u003c= 7.1.27, which allows a remote attacker to reuse, spoof, or steal other user and admin sessions.","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":"Insufficient Session Expiration in TopEase","id":"CVE-2021-42545","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Reflected XSS in search functionality of WP Cloud Plugins - Use-Your-Drive","id":"CVE-2021-42546"},"packages":[],"prev":{"headline":"Lack of Rate limiting in Authentication in TopEase","id":"CVE-2021-42544"},"products":["TopEase"],"published":"2021-11-30","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Business-DNA Solutions GmbH"]},"summary":"Remote attackers can reuse or steal user and admin sessions due to insufficient session expiration, leading to account takeover.","url":"https://insights.sbomify.com/CVE-2021-42545/"}
