It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-5748 in the wild and no public exploit code.\n\nAffected product: Synology SSL VPN Client. 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-2023-5748/ (Markdown: https://insights.sbomify.com/CVE-2023-5748/index.md)","id":"CVE-2023-5748","markdown":"https://insights.sbomify.com/CVE-2023-5748/index.md","name":"CVE-2023-5748","record":{"aliases":["GHSA-3744-988x-mqxh"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Synology SSL VPN Client","requires_auth":"low_privilege","summary":"Local attackers can cause a denial of service in Synology SSL VPN Client via a buffer overflow in the CGI component.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"ssl_vpn_client","vendor":"synology"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer copy without checking size of input ('Classic Buffer Overflow') vulnerability in cgi component in Synology SSL VPN Client before 1.4.7-0687 allows local users to conduct denial-of-service attacks 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 Synology SSL VPN Client","id":"CVE-2023-5748","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"EmbedPress \u003c 3.9.2 - Reflected XSS","id":"CVE-2023-5749"},"packages":[],"prev":{"headline":"Command injection via wave install file","id":"CVE-2023-5747"},"products":["Synology SSL VPN Client"],"published":"2023-10-24","related":[{"cvss_score":8.8,"headline":"Security feature bypass in SSL VPN Client","id":"CVE-2018-13283","kev_date_added":null,"published":"2019-04-01"},{"cvss_score":8.1,"headline":"Information disclosure in Synology SSL VPN Client","id":"CVE-2021-47961","kev_date_added":null,"published":"2026-04-10"},{"cvss_score":7.3,"headline":"Security feature bypass in SSL VPN Client","id":"CVE-2018-8929","kev_date_added":null,"published":"2018-07-06"},{"cvss_score":6.5,"headline":"Information disclosure in Synology SSL VPN Client","id":"CVE-2021-47960","kev_date_added":null,"published":"2026-04-10"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-17","vendors":["Synology"]},"summary":"Local attackers can cause a denial of service in Synology SSL VPN Client via a buffer overflow in the CGI component.","url":"https://insights.sbomify.com/CVE-2023-5748/"}
