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-2018-8238 in the wild and no public exploit code.\n\nAffected product: Microsoft Lync. 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-2018-8238/ (Markdown: https://insights.sbomify.com/CVE-2018-8238/index.md)","id":"CVE-2018-8238","markdown":"https://insights.sbomify.com/CVE-2018-8238/index.md","name":"CVE-2018-8238","record":{"aliases":["GHSA-v74r-x7x3-53vj"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Skype for Business","requires_auth":"none","summary":"Attackers can bypass security features in Skype for Business or Lync by sharing malicious UNC path links via messages.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"lync","vendor":"microsoft"},{"product":"skype_for_business","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"A security feature bypass vulnerability exists when Skype for Business or Lync do not properly parse UNC path links shared via messages, aka \"Skype for Business and Lync Security Feature Bypass Vulnerability.\" This affects Skype, Microsoft Lync.","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 Microsoft Lync","id":"CVE-2018-8238","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in Windows 10","id":"CVE-2018-8239"},"packages":[],"prev":{"headline":"Memory corruption in Microsoft Edge","id":"CVE-2018-8236"},"products":["Microsoft Lync","Skype"],"published":"2018-07-11","related":[{"cvss_score":9.8,"headline":"Microsoft Office Elevation of Privilege Vulnerability","id":"CVE-2020-1025","kev_date_added":null,"published":"2020-07-14"},{"cvss_score":9.3,"headline":"Use after free in n/a","id":"CVE-2013-1302","kev_date_added":null,"published":"2013-05-15"},{"cvss_score":9.3,"headline":"Path traversal in n/a","id":"CVE-2012-1849","kev_date_added":null,"published":"2012-06-12"},{"cvss_score":8.8,"headline":"Code injection in Microsoft Lync","id":"CVE-2018-8311","kev_date_added":null,"published":"2018-07-11"},{"cvss_score":8.8,"headline":"Auth bypass in Skype for Business","id":"CVE-2017-11786","kev_date_added":null,"published":"2017-10-13"},{"cvss_score":8.8,"headline":"Memory corruption in Uniscribe","id":"CVE-2017-0283","kev_date_added":null,"published":"2017-06-15"},{"cvss_score":8.8,"headline":"Memory corruption in Graphics","id":"CVE-2017-8527","kev_date_added":null,"published":"2017-06-15"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Microsoft"]},"summary":"Attackers can bypass security features in Skype for Business or Lync by sharing malicious UNC path links via messages.","url":"https://insights.sbomify.com/CVE-2018-8238/"}
