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-2018-8918 in the wild and no public exploit code.\n\nAffected product: Synology Router Manager. 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-2018-8918/ (Markdown: https://insights.sbomify.com/CVE-2018-8918/index.md)","id":"CVE-2018-8918","markdown":"https://insights.sbomify.com/CVE-2018-8918/index.md","name":"CVE-2018-8918","record":{"aliases":["GHSA-wc3h-m5p7-867x"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology Router Manager","requires_auth":"low_privilege","summary":"Remote attackers can inject arbitrary web script or HTML via the host parameter in Synology Router Manager, potentially leading to session hijacking or malicious actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"router_manager","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 info.cgi in Synology Router Manager (SRM) before 1.1.7-6941 allows remote attackers to inject arbitrary web script or HTML via the host 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 Synology Router Manager (SRM)","id":"CVE-2018-8918","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"synology:router_manager","products":["synology:router_manager"],"type":"xss","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in DiskStation Manager (DSM)","id":"CVE-2018-8919"},"packages":[],"prev":{"headline":"Cross-site scripting in DiskStation Manager (DSM)","id":"CVE-2018-8917"},"products":["Synology Router Manager (SRM)"],"published":"2018-12-24","related":[{"cvss_score":9.8,"headline":"Command injection in Synology Router Manager (SRM)","id":"CVE-2023-32956","kev_date_added":null,"published":"2023-05-16"},{"cvss_score":9.8,"headline":"Command injection in Synology Router Manager (SRM)","id":"CVE-2020-27654","kev_date_added":null,"published":"2020-10-29"},{"cvss_score":8.6,"headline":"Denial of service in Synology Router Manager (SRM)","id":"CVE-2019-11823","kev_date_added":null,"published":"2020-05-04"},{"cvss_score":8.3,"headline":"Security feature bypass in Synology Router Manager (SRM)","id":"CVE-2020-27649","kev_date_added":null,"published":"2020-10-29"},{"cvss_score":8.1,"headline":"Path traversal in Synology Router Manager (SRM)","id":"CVE-2024-11398","kev_date_added":null,"published":"2024-12-04"},{"cvss_score":8.1,"headline":"Command injection in Synology Router Manager (SRM)","id":"CVE-2023-32955","kev_date_added":null,"published":"2023-05-16"},{"cvss_score":7.5,"headline":"Supply chain in Synology Router Manager (SRM)","id":"CVE-2024-39348","kev_date_added":null,"published":"2024-06-28"}],"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":"2024-09-17","vendors":["Synology"]},"summary":"Remote attackers can inject arbitrary web script or HTML via the host parameter in Synology Router Manager, potentially leading to session hijacking or malicious actions.","url":"https://insights.sbomify.com/CVE-2018-8918/"}
