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-2020-13817 in the wild and no public exploit code.\n\nAffected product: Netapp Cloud Backup. 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-2020-13817/ (Markdown: https://insights.sbomify.com/CVE-2020-13817/index.md)","id":"CVE-2020-13817","markdown":"https://insights.sbomify.com/CVE-2020-13817/index.md","name":"CVE-2020-13817","record":{"aliases":["CLSA-2024-1735122554","CLSA-2024-1735128099","CVE-2020-13816","DEBIAN-CVE-2020-13817","GHSA-fx6x-7xgx-2wwp","UBUNTU-CVE-2020-13817"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"NTP daemon","requires_auth":"none","summary":"Remote attackers can cause NTP daemon exit or system time changes by spoofing packets if unauthenticated IPv4 sources are used.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"m10-1_firmware","vendor":"fujitsu"},{"product":"m10-4_firmware","vendor":"fujitsu"},{"product":"m10-4s_firmware","vendor":"fujitsu"},{"product":"m12-1_firmware","vendor":"fujitsu"},{"product":"m12-2_firmware","vendor":"fujitsu"},{"product":"m12-2s_firmware","vendor":"fujitsu"},{"product":"cloud_backup","vendor":"netapp"},{"product":"clustered_data_ontap","vendor":"netapp"},{"product":"data_ontap","vendor":"netapp"},{"product":"element_software","vendor":"netapp"},{"product":"h300e_firmware","vendor":"netapp"},{"product":"h300s_firmware","vendor":"netapp"},{"product":"h410c_firmware","vendor":"netapp"},{"product":"h410s_firmware","vendor":"netapp"},{"product":"h500e_firmware","vendor":"netapp"},{"product":"h500s_firmware","vendor":"netapp"},{"product":"h700e_firmware","vendor":"netapp"},{"product":"h700s_firmware","vendor":"netapp"},{"product":"hci_compute_node_firmware","vendor":"netapp"},{"product":"hci_management_node","vendor":"netapp"},{"product":"ontap_tools","vendor":"netapp"},{"product":"solidfire","vendor":"netapp"},{"product":"steelstore_cloud_integrated_storage","vendor":"netapp"},{"product":"ntp","vendor":"ntp"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.0/AC:H/AV:N/A:H/C:N/I:N/PR:N/S:U/UI:N","version":"3.0"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"}],"description":"ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets.
