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-2023-39543 in the wild and no public exploit code.\n\nAffected product: LuxSoft  LuxCal Web Calendar. 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-2023-39543/ (Markdown: https://insights.sbomify.com/CVE-2023-39543/index.md)","id":"CVE-2023-39543","markdown":"https://insights.sbomify.com/CVE-2023-39543/index.md","name":"CVE-2023-39543","record":{"aliases":["GHSA-qqrg-2fcm-mwrq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"LuxCal Web Calendar","requires_auth":"none","summary":"Remote unauthenticated attackers can execute arbitrary scripts in users' browsers via a cross-site scripting vulnerability in LuxCal Web Calendar.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"luxcal_web_calendar","vendor":"luxsoft"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site scripting vulnerability in LuxCal Web Calendar prior to 5.2.3M (MySQL version) and LuxCal Web Calendar prior to 5.2.3L (SQLite version) allows a remote unauthenticated attacker to execute an arbitrary script on the web browser of the user who is using the product.","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 LuxCal Web Calendar","id":"CVE-2023-39543","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Auth bypass in CLUSTERPRO X SingleServerSafe (EXPRESSCLUSTER X SingleServerSafe)","id":"CVE-2023-39544"},"packages":[],"prev":{"headline":"Path traversal in Foxit Reader","id":"CVE-2023-39542"},"products":["LuxCal Web Calendar"],"published":"2023-08-21","related":[{"cvss_score":9.8,"headline":"SQL injection in LuxCal Web Calendar","id":"CVE-2023-46700","kev_date_added":null,"published":"2023-11-20"},{"cvss_score":9.1,"headline":"SQL injection in LuxCal Web Calendar","id":"CVE-2023-39939","kev_date_added":null,"published":"2023-08-21"},{"cvss_score":7.3,"headline":"SQL injection in The LuxCal Web Calendar","id":"CVE-2025-25221","kev_date_added":null,"published":"2025-02-18"},{"cvss_score":7.3,"headline":"SQL injection in The LuxCal Web Calendar","id":"CVE-2025-25222","kev_date_added":null,"published":"2025-02-18"},{"cvss_score":6.1,"headline":"Cross-site scripting in LuxCal Web Calendar","id":"CVE-2023-47175","kev_date_added":null,"published":"2023-11-20"},{"cvss_score":5.8,"headline":"Path traversal in The LuxCal Web Calendar","id":"CVE-2025-25223","kev_date_added":null,"published":"2025-02-18"}],"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":"2024-10-04","vendors":["LuxSoft "]},"summary":"Remote unauthenticated attackers can execute arbitrary scripts in users' browsers via a cross-site scripting vulnerability in LuxCal Web Calendar.","url":"https://insights.sbomify.com/CVE-2023-39543/"}
