It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20616 in the wild and no public exploit code.\n\nAffected product: SKYSEA Client View. 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-2021-20616/ (Markdown: https://insights.sbomify.com/CVE-2021-20616/index.md)","id":"CVE-2021-20616","markdown":"https://insights.sbomify.com/CVE-2021-20616/index.md","name":"CVE-2021-20616","record":{"aliases":["GHSA-qrhf-q88m-c43r"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SKYSEA Client View","requires_auth":"none","summary":"An attacker can gain privileges by placing a malicious DLL in a directory searched by the SKYSEA Client View installer.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"skysea_client_view","vendor":"skygroup"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"}],"description":"Untrusted search path vulnerability in the installer of SKYSEA Client View Ver.1.020.05b to Ver.16.001.01g allows an attacker to gain privileges via a Trojan horse DLL in an unspecified directory.","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":"Privilege escalation in SKYSEA Client View","id":"CVE-2021-20616","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in acmailer and acmailer DB","id":"CVE-2021-20617"},"packages":[],"prev":{"headline":"Denial of service in MELSEC-F series FX3U-ENET; MELSEC-F series FX3U-ENET-L; MELSEC-F series FX3U-ENET-P502","id":"CVE-2021-20613"},"products":["SKYSEA Client View"],"published":"2021-01-13","related":[{"cvss_score":9.8,"headline":"SKYSEA Client View Improper Authentication","id":"CVE-2016-7836","kev_date_added":"2025-10-14","published":"2017-06-09"},{"cvss_score":7.8,"headline":"Privilege escalation in SKYSEA Client View","id":"CVE-2024-41139","kev_date_added":null,"published":"2024-07-29"},{"cvss_score":7.8,"headline":"Privilege escalation in SKYSEA Client View","id":"CVE-2024-41143","kev_date_added":null,"published":"2024-07-29"},{"cvss_score":7.8,"headline":"Missing authorization in SKYSEA Client View","id":"CVE-2024-21805","kev_date_added":null,"published":"2024-03-12"},{"cvss_score":7.8,"headline":"Privilege escalation in SKYSEA Client View","id":"CVE-2020-5617","kev_date_added":null,"published":"2020-08-04"},{"cvss_score":7.5,"headline":"Path traversal in SKYSEA Client View","id":"CVE-2024-41726","kev_date_added":null,"published":"2024-07-29"}],"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":"2024-08-03","vendors":["Sky Co., LTD."]},"summary":"An attacker can gain privileges by placing a malicious DLL in a directory searched by the SKYSEA Client View installer.","url":"https://insights.sbomify.com/CVE-2021-20616/"}
