An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-0798 in the wild and no public exploit code.\n\nAffected product: Microsoft Lync Server 2013. 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-2019-0798/ (Markdown: https://insights.sbomify.com/CVE-2019-0798/index.md)","id":"CVE-2019-0798","markdown":"https://insights.sbomify.com/CVE-2019-0798/index.md","name":"CVE-2019-0798","record":{"aliases":["GHSA-43cx-jhp3-2qcr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Skype for Business Server","requires_auth":"none","summary":"Attackers can spoof content in Skype for Business or Lync Server by exploiting improper request sanitization, potentially misleading users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"lync_server","vendor":"microsoft"},{"product":"skype_for_business_server","vendor":"microsoft"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A spoofing vulnerability exists when a Lync Server or Skype for Business Server does not properly sanitize a specially crafted request, aka 'Skype for Business and Lync Spoofing Vulnerability'.","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":"Cross-site scripting in Microsoft Lync Server 2013","id":"CVE-2019-0798","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2019-0799"},"packages":[],"prev":{"headline":"Microsoft Win32k Privilege Escalation","id":"CVE-2019-0797"},"products":["Microsoft Lync Server 2013","Skype for Business Server 2015"],"published":"2019-04-09","related":[{"cvss_score":7.2,"headline":"Skype for Business and Lync Remote Code Execution Vulnerability","id":"CVE-2022-33633","kev_date_added":null,"published":"2022-07-12"},{"cvss_score":7.2,"headline":"Skype for Business and Lync Remote Code Execution Vulnerability","id":"CVE-2021-26422","kev_date_added":null,"published":"2021-05-11"},{"cvss_score":6.5,"headline":"Skype for Business Information Disclosure Vulnerability","id":"CVE-2022-26911","kev_date_added":null,"published":"2022-04-15"},{"cvss_score":6.5,"headline":"Skype for Business and Lync Spoofing Vulnerability","id":"CVE-2021-26421","kev_date_added":null,"published":"2021-05-11"},{"cvss_score":6.5,"headline":"Skype for Business and Lync Spoofing Vulnerability","id":"CVE-2021-24073","kev_date_added":null,"published":"2021-02-25"},{"cvss_score":6.5,"headline":"Skype for Business and Lync Denial of Service Vulnerability","id":"CVE-2021-24099","kev_date_added":null,"published":"2021-02-25"}],"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":["Microsoft"]},"summary":"Attackers can spoof content in Skype for Business or Lync Server by exploiting improper request sanitization, potentially misleading users.","url":"https://insights.sbomify.com/CVE-2019-0798/"}
