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-2020-24359 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hashicorp/vault-ssh-helper (Go): affected all versions; fixed in 0.2.0\n- github.com/hashicorp/vault-ssh-helper (Go): affected all versions; fixed in 0.2.0\n- github.com/hashicorp/vault-ssh-helper (Go): affected all versions; fixed in 0.2.0\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-2020-24359/ (Markdown: https://insights.sbomify.com/CVE-2020-24359/index.md)","id":"CVE-2020-24359","markdown":"https://insights.sbomify.com/CVE-2020-24359/index.md","name":"CVE-2020-24359","record":{"aliases":["GHSA-f9fq-vjvh-779p","GO-2022-0824"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Vault SSH helper","requires_auth":"none","summary":"Attackers can use SSH OTPs for any IP in the host's subnet, bypassing specific IP restrictions in HashiCorp Vault SSH helper.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"vault-ssh-helper","vendor":"hashicorp"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"HashiCorp vault-ssh-helper up to and including version 0.1.6 incorrectly accepted Vault-issued SSH OTPs for the subnet in which a host's network interface was located, rather than the specific IP address assigned to that interface.
