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-2021-42809 in the wild and no public exploit code.\n\nAffected product: Thales Sentinel Protection Installer. 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-2021-42809/ (Markdown: https://insights.sbomify.com/CVE-2021-42809/index.md)","id":"CVE-2021-42809","markdown":"https://insights.sbomify.com/CVE-2021-42809/index.md","name":"CVE-2021-42809","record":{"aliases":["GHSA-qqf6-7934-8vv8"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Sentinel Protection Installer","requires_auth":"high_privilege","summary":"An attacker can execute arbitrary code via DLL hijacking in the Sentinel Protection Installer due to improper access control.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"THA-PSIRT","cpe":[{"product":"sentinel_protection_installer","vendor":"thalesgroup"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-913","name":"Improper Control of Dynamically-Managed Code Resources"}],"description":"Improper Access Control of Dynamically-Managed Code Resources (DLL) in Thales Sentinel Protection Installer could allow the execution of arbitrary code.","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":"The Sentinel Protection Installer 7.7.0 does not properly restrict loading Dynamic Link Library","id":"CVE-2021-42809","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in SafeNet Authentication Service","id":"CVE-2021-42810"},"packages":[],"prev":{"headline":"Privilege escalation in Sentinel Protection Installer","id":"CVE-2021-42808"},"products":["Sentinel Protection Installer"],"published":"2021-12-20","related":[{"cvss_score":6.5,"headline":"Privilege escalation in Sentinel Protection Installer","id":"CVE-2021-42808","kev_date_added":null,"published":"2021-12-20"}],"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":["Thales"]},"summary":"An attacker can execute arbitrary code via DLL hijacking in the Sentinel Protection Installer due to improper access control.","url":"https://insights.sbomify.com/CVE-2021-42809/"}
