Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-8915 in the wild and no public exploit code.\n\nAffected product: Synology 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-2018-8915/ (Markdown: https://insights.sbomify.com/CVE-2018-8915/index.md)","id":"CVE-2018-8915","markdown":"https://insights.sbomify.com/CVE-2018-8915/index.md","name":"CVE-2018-8915","record":{"aliases":["GHSA-jc52-h9fr-wjmq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology Calendar","requires_auth":"low_privilege","summary":"Authenticated attackers can inject arbitrary scripts via the title parameter in Synology Calendar's Notification Center, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"calendar","vendor":"synology"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site scripting (XSS) vulnerability in Notification Center in Synology Calendar before 2.1.1-0502 allows remote authenticated users to inject arbitrary web script or HTML via title parameter.","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 Calendar","id":"CVE-2018-8915","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in DiskStation Manager (DSM)","id":"CVE-2018-8916"},"packages":[],"prev":{"headline":"SQL injection in Media Server","id":"CVE-2018-8914"},"products":["Calendar"],"published":"2018-05-10","related":[{"cvss_score":7.3,"headline":"Command injection in Calendar","id":"CVE-2019-11829","kev_date_added":null,"published":"2019-06-30"},{"cvss_score":6.5,"headline":"Cross-site request forgery in Synology Calendar","id":"CVE-2022-22686","kev_date_added":null,"published":"2022-07-26"},{"cvss_score":6.5,"headline":"Cross-site scripting in Synology Calendar","id":"CVE-2022-22682","kev_date_added":null,"published":"2022-07-12"},{"cvss_score":6.5,"headline":"Cross-site scripting in Calendar","id":"CVE-2019-11825","kev_date_added":null,"published":"2019-06-30"},{"cvss_score":6.5,"headline":"Missing authorization in Synology Calendar","id":"CVE-2017-15891","kev_date_added":null,"published":"2017-12-08"},{"cvss_score":5.8,"headline":"Hardcoded credentials in Synology Calendar","id":"CVE-2021-34812","kev_date_added":null,"published":"2021-06-18"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Synology"]},"summary":"Authenticated attackers can inject arbitrary scripts via the title parameter in Synology Calendar's Notification Center, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2018-8915/"}
