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-2022-43931 in the wild and no public exploit code.\n\nAffected product: Synology VPN Plus Server. 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-2022-43931/ (Markdown: https://insights.sbomify.com/CVE-2022-43931/index.md)","id":"CVE-2022-43931","markdown":"https://insights.sbomify.com/CVE-2022-43931/index.md","name":"CVE-2022-43931","record":{"aliases":["GHSA-xvg3-q6r5-8fhf"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"VPN Plus Server","requires_auth":"none","summary":"Remote attackers can execute arbitrary commands via an out-of-bounds write in Synology VPN Plus Server's remote desktop functionality.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"vpn_plus_server","vendor":"synology"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Out-of-bounds write vulnerability in Remote Desktop Functionality in Synology VPN Plus Server before 1.4.3-0534 and 1.4.4-0635 allows remote attackers to execute arbitrary commands 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":"Memory corruption in VPN Plus Server","id":"CVE-2022-43931","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Synology Router Manager (SRM)","id":"CVE-2022-43932"},"packages":[],"prev":{"headline":"IBM Db2 for Linux, UNIX and Windows information disclosure","id":"CVE-2022-43930"},"products":["VPN Plus Server"],"published":"2023-01-03","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-10","vendors":["Synology"]},"summary":"Remote attackers can execute arbitrary commands via an out-of-bounds write in Synology VPN Plus Server's remote desktop functionality.","url":"https://insights.sbomify.com/CVE-2022-43931/"}
