An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2018-15919 exists.\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-2018-15919/ (Markdown: https://insights.sbomify.com/CVE-2018-15919/index.md)","id":"CVE-2018-15919","markdown":"https://insights.sbomify.com/CVE-2018-15919/index.md","name":"CVE-2018-15919","record":{"aliases":["DEBIAN-CVE-2018-15919","GHSA-rj3q-q9f3-gr2v","ROOT-OS-DEBIAN-12-CVE-2018-15919","UBUNTU-CVE-2018-15919"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenSSH server","requires_auth":"none","summary":"Remote attackers can enumerate valid usernames on OpenSSH servers when GSS2 authentication is enabled, revealing user existence.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cloud_backup","vendor":"netapp"},{"product":"cn1610_firmware","vendor":"netapp"},{"product":"data_ontap_edge","vendor":"netapp"},{"product":"ontap_select_deploy","vendor":"netapp"},{"product":"steelstore","vendor":"netapp"},{"product":"openssh","vendor":"openbsd"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use.
