Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-15886 in the wild and no public exploit code.\n\nAffected product: Synology Chat. 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-2017-15886/ (Markdown: https://insights.sbomify.com/CVE-2017-15886/index.md)","id":"CVE-2017-15886","markdown":"https://insights.sbomify.com/CVE-2017-15886/index.md","name":"CVE-2017-15886","record":{"aliases":["GHSA-p6m5-7r2m-h3px"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology Chat","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit SSRF in Synology Chat to download arbitrary local files via crafted URIs.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"chat","vendor":"synology"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Server-side request forgery (SSRF) vulnerability in Link Preview in Synology Chat before 2.0.0-1124 allows remote authenticated users to download arbitrary local files via a crafted URI.","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 Chat","id":"CVE-2017-15886","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in Synology CardDAV Server","id":"CVE-2017-15887"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2017-15885"},"products":["Chat"],"published":"2017-12-28","related":[{"cvss_score":6.5,"headline":"Server-side request forgery in Synology Chat","id":"CVE-2017-11148","kev_date_added":null,"published":"2017-08-11"},{"cvss_score":5.4,"headline":"Cross-site scripting in Chat","id":"CVE-2017-15892","kev_date_added":null,"published":"2017-12-28"}],"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":"2024-09-16","vendors":["Synology"]},"summary":"Authenticated attackers can exploit SSRF in Synology Chat to download arbitrary local files via crafted URIs.","url":"https://insights.sbomify.com/CVE-2017-15886/"}
