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-2021-28847 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-2021-28847/ (Markdown: https://insights.sbomify.com/CVE-2021-28847/index.md)","id":"CVE-2021-28847","markdown":"https://insights.sbomify.com/CVE-2021-28847/index.md","name":"CVE-2021-28847","record":{"aliases":["GHSA-whgp-9qjc-434f"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SSH client","requires_auth":"none","summary":"A remote server can cause a denial of service in MobaXterm by sending rapid tab title change requests, hanging the Windows GUI.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mobaxterm","vendor":"mobatek"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"MobaXterm before 21.0 allows remote servers to cause a denial of service (Windows GUI hang) via tab title change requests that are sent repeatedly at high speed, which results in many SetWindowTextA or SetWindowTextW calls.","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":"Denial of service in n/a","id":"CVE-2021-28847","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-28848"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-28846"},"products":["n/a"],"published":"2021-06-03","related":[{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2019-7690","kev_date_added":null,"published":"2019-05-13"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-15376","kev_date_added":null,"published":"2017-10-16"},{"cvss_score":9.1,"headline":"Hardcoded credentials in n/a","id":"CVE-2022-38337","kev_date_added":null,"published":"2022-12-05"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2019-16305","kev_date_added":null,"published":"2019-09-14"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2019-13475","kev_date_added":null,"published":"2019-07-09"},{"cvss_score":8.5,"headline":"MobaXterm \u003c 26.1 Notepad++ Unquoted Service Path","id":"CVE-2026-25866","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":8.1,"headline":"Auth bypass in n/a","id":"CVE-2022-38336","kev_date_added":null,"published":"2022-12-05"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"A remote server can cause a denial of service in MobaXterm by sending rapid tab title change requests, hanging the Windows GUI.","url":"https://insights.sbomify.com/CVE-2021-28847/"}
