An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-34808 in the wild and no public exploit code.\n\nAffected product: Synology Media Server. 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-2021-34808/ (Markdown: https://insights.sbomify.com/CVE-2021-34808/index.md)","id":"CVE-2021-34808","markdown":"https://insights.sbomify.com/CVE-2021-34808/index.md","name":"CVE-2021-34808","record":{"aliases":["GHSA-x9fw-v6jg-w952"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology Media Server","requires_auth":"none","summary":"Remote attackers can access intranet resources via SSRF in Synology Media Server, requiring an upgrade to mitigate.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"media_server","vendor":"synology"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Server-Side Request Forgery (SSRF) vulnerability in cgi component in Synology Media Server before 1.8.3-2881 allows remote attackers to access intranet resources via unspecified vectors.","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":"Server-side request forgery in Media Server","id":"CVE-2021-34808","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in Download Station","id":"CVE-2021-34809"},"packages":[],"prev":{"headline":"Open redirect in n/a","id":"CVE-2021-34807"},"products":["Media Server"],"published":"2021-06-18","related":[{"cvss_score":10,"headline":"Memory corruption in Media Server","id":"CVE-2022-22683","kev_date_added":null,"published":"2022-07-28"},{"cvss_score":7.5,"headline":"Missing authorization in Media Server","id":"CVE-2024-4464","kev_date_added":null,"published":"2024-12-18"},{"cvss_score":7.3,"headline":"SQL injection in Synology Media Server","id":"CVE-2021-33180","kev_date_added":null,"published":"2021-06-01"},{"cvss_score":7.3,"headline":"SQL injection in Media Server","id":"CVE-2018-8914","kev_date_added":null,"published":"2018-05-10"},{"cvss_score":5.3,"headline":"Information disclosure in Media Server","id":"CVE-2022-27614","kev_date_added":null,"published":"2022-07-28"}],"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 access intranet resources via SSRF in Synology Media Server, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2021-34808/"}
