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-2021-42544 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-2021-42544/ (Markdown: https://insights.sbomify.com/CVE-2021-42544/index.md)","id":"CVE-2021-42544","markdown":"https://insights.sbomify.com/CVE-2021-42544/index.md","name":"CVE-2021-42544","record":{"aliases":["GHSA-jxgv-3jv5-8mh9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"TopEase platform","requires_auth":"none","summary":"An unauthenticated attacker can bypass login rate limits to brute-force credentials and gain unauthorized access to the TopEase platform.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[{"product":"topease","vendor":"businessdnasolutions"}],"cvss":{"score":7.5,"severity":"high","source":"cna","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-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"Missing Rate Limiting in Web Applications operating on Business-DNA Solutions GmbH’s TopEase® Platform Version \u003c= 7.1.27 on the Login Form allows an unauthenticated remote attacker to perform multiple login attempts, which facilitates gaining privileges.","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":"Lack of Rate limiting in Authentication in TopEase","id":"CVE-2021-42544","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Insufficient Session Expiration in TopEase","id":"CVE-2021-42545"},"packages":[],"prev":{"headline":"AzeoTech DAQFactory","id":"CVE-2021-42543"},"products":["TopEase"],"published":"2021-11-30","related":[{"cvss_score":8.1,"headline":"Missing HTTPOnly flag on sensitive cookie in TopEase","id":"CVE-2021-42115","kev_date_added":null,"published":"2021-11-30"},{"cvss_score":8.1,"headline":"Stored XSS in TopEase","id":"CVE-2021-42118","kev_date_added":null,"published":"2021-11-30"},{"cvss_score":7.3,"headline":"Stored XSS in Search Function in TopEase","id":"CVE-2021-42119","kev_date_added":null,"published":"2021-11-30"},{"cvss_score":7.3,"headline":"Missing Upload Filter in TopEase","id":"CVE-2021-42123","kev_date_added":null,"published":"2021-11-30"},{"cvss_score":6.5,"headline":"Missing Character Length (Denial of Service) in TopEase","id":"CVE-2021-42120","kev_date_added":null,"published":"2021-11-30"},{"cvss_score":4.3,"headline":"Unauthorized Menu Item Access in TopEase","id":"CVE-2021-42116","kev_date_added":null,"published":"2021-11-30"}],"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":"An unauthenticated attacker can bypass login rate limits to brute-force credentials and gain unauthorized access to the TopEase platform.","url":"https://insights.sbomify.com/CVE-2021-42544/"}
