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-2019-11823 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-2019-11823/ (Markdown: https://insights.sbomify.com/CVE-2019-11823/index.md)","id":"CVE-2019-11823","markdown":"https://insights.sbomify.com/CVE-2019-11823/index.md","name":"CVE-2019-11823","record":{"aliases":["GHSA-x39q-8mm3-jqpx"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology Router Manager","requires_auth":"none","summary":"Remote attackers can cause a denial of service via crafted network traffic in Synology Router Manager, requiring an upgrade to fix.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"router_manager","vendor":"synology"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"CRLF injection vulnerability in Network Center in Synology Router Manager (SRM) before 1.2.3-8017-2 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted network traffic.","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":"Denial of service in Synology Router Manager (SRM)","id":"CVE-2019-11823","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"synology:router_manager","products":["synology:router_manager"],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2019-11824"},"packages":[],"prev":{"headline":"Path traversal in Photo Station","id":"CVE-2019-11822"},"products":["Synology Router Manager (SRM)"],"published":"2020-05-04","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":8.3,"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":"2024-09-16","vendors":["Synology"]},"summary":"Remote attackers can cause a denial of service via crafted network traffic in Synology Router Manager, requiring an upgrade to fix.","url":"https://insights.sbomify.com/CVE-2019-11823/"}
