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-2018-8929 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-2018-8929/ (Markdown: https://insights.sbomify.com/CVE-2018-8929/index.md)","id":"CVE-2018-8929","markdown":"https://insights.sbomify.com/CVE-2018-8929/index.md","name":"CVE-2018-8929","record":{"aliases":["GHSA-x728-vr6f-27f3"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology SSL VPN Client","requires_auth":"none","summary":"Remote attackers can intercept VPN traffic via man-in-the-middle attacks due to improper endpoint restrictions in the Synology SSL VPN Client.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"ssl_vpn_client","vendor":"synology"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-417","name":null},{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"Improper restriction of communication channel to intended endpoints vulnerability in HTTP daemon in Synology SSL VPN Client before 1.2.4-0224 allows remote attackers to conduct man-in-the-middle attacks via a crafted payload.","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":"Security feature bypass in SSL VPN Client","id":"CVE-2018-8929","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2018-8930"},"packages":[],"prev":{"headline":"Cross-site scripting in CardDAV Server","id":"CVE-2018-8928"},"products":["SSL VPN Client"],"published":"2018-07-06","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":6.5,"headline":"Information disclosure in Synology SSL VPN Client","id":"CVE-2021-47960","kev_date_added":null,"published":"2026-04-10"},{"cvss_score":3.3,"headline":"Memory corruption in Synology SSL VPN Client","id":"CVE-2023-5748","kev_date_added":null,"published":"2023-10-24"}],"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":"2024-09-16","vendors":["Synology"]},"summary":"Remote attackers can intercept VPN traffic via man-in-the-middle attacks due to improper endpoint restrictions in the Synology SSL VPN Client.","url":"https://insights.sbomify.com/CVE-2018-8929/"}
