An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-41763 and fix it if it is affected.\n\nWhat it is: CVE-2023-41763 is a medium-severity server-side request forgery vulnerability in Microsoft Skype for Business Server 2015 CU13, published on 10 Oct 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2023-41763 in the wild since at least 10 Oct 2023.\n\nAffected product: Microsoft Skype for Business Server 2015 CU13. 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-2023-41763/ (Markdown: https://insights.sbomify.com/CVE-2023-41763/index.md)","id":"CVE-2023-41763","markdown":"https://insights.sbomify.com/CVE-2023-41763/index.md","name":"CVE-2023-41763","record":{"aliases":["GHSA-7997-4r78-h34m"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Skype for Business Server","requires_auth":"none","summary":"An attacker can exploit Server-Side Request Forgery in Skype for Business Server to escalate privileges and access sensitive data.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"skype_for_business_server","vendor":"microsoft"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Skype for Business Elevation of Privilege Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2023/CVE-2023-41763.yaml","stars":null,"title":"Skype for Business 2019 (SfB) - Blind Server-side Request Forgery"}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Skype for Business Privilege Escalation","id":"CVE-2023-41763","indexable":true,"kev":{"dateAdded":"2023-10-10","dueDate":"2023-10-31","knownRansomwareCampaignUse":"Unknown","product":"Skype for Business","requiredAction":"Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Skype for Business Privilege Escalation Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Office Spoofing Vulnerability","id":"CVE-2023-41764"},"packages":[],"prev":{"headline":"Apache Traffic Server: s3_auth plugin problem with hash calculation","id":"CVE-2023-41752"},"products":["Skype for Business Server 2015 CU13","Skype for Business Server 2019 CU7"],"published":"2023-10-10","related":[{"cvss_score":9.8,"headline":"Skype for Business Remote Code Execution Vulnerability","id":"CVE-2026-66302","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":8.3,"headline":"Skype for Business Spoofing Vulnerability","id":"CVE-2026-69646","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":7.5,"headline":"Skype for Business Information Disclosure Vulnerability","id":"CVE-2026-66304","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":7.5,"headline":"Skype for Business and Lync Denial of Service Vulnerability","id":"CVE-2026-66307","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":7.2,"headline":"Skype for Business Remote Code Execution Vulnerability","id":"CVE-2023-36780","kev_date_added":null,"published":"2023-10-10"},{"cvss_score":7.2,"headline":"Skype for Business Remote Code Execution Vulnerability","id":"CVE-2023-36786","kev_date_added":null,"published":"2023-10-10"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Microsoft"]},"summary":"An attacker can exploit Server-Side Request Forgery in Skype for Business Server to escalate privileges and access sensitive data.","url":"https://insights.sbomify.com/CVE-2023-41763/"}
