Cybozu Desktop for Windows, published on 25 May 2020. 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-2020-5537 in the wild and no public exploit code.\n\nAffected product: Cybozu, Inc. Cybozu Desktop for Windows. 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-2020-5537/ (Markdown: https://insights.sbomify.com/CVE-2020-5537/index.md)","id":"CVE-2020-5537","markdown":"https://insights.sbomify.com/CVE-2020-5537/index.md","name":"CVE-2020-5537","record":{"aliases":["GHSA-cwg3-995c-r2wj"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cybozu Desktop","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Cybozu Desktop for Windows installations, requiring users to upgrade to a patched version.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"desktop","vendor":"cybozu"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Cybozu Desktop for Windows 2.0.23 to 2.2.40 allows remote code execution via unspecified vectors.","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":"Code injection in Cybozu Desktop for Windows","id":"CVE-2020-5537","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Privilege escalation in PALLET CONTROL","id":"CVE-2020-5538"},"packages":[],"prev":{"headline":"Auth bypass in OpenBlocks IoT VX2","id":"CVE-2020-5536"},"products":["Cybozu Desktop for Windows"],"published":"2020-05-25","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":["Cybozu, Inc."]},"summary":"Remote attackers can execute arbitrary code on Cybozu Desktop for Windows installations, requiring users to upgrade to a patched version.","url":"https://insights.sbomify.com/CVE-2020-5537/"}
