Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-20046 in the wild and no public exploit code.\n\nAffected product: Cisco ASR 5000 Series Software. 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-2023-20046/ (Markdown: https://insights.sbomify.com/CVE-2023-20046/index.md)","id":"CVE-2023-20046","markdown":"https://insights.sbomify.com/CVE-2023-20046/index.md","name":"CVE-2023-20046","record":{"aliases":[],"analysis":{"component_type":"network_device","fix_type":"workaround","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco StarOS Software","requires_auth":"low_privilege","summary":"An authenticated attacker can elevate privileges by using a low-privileged SSH key from a trusted IP address, requiring workarounds for mitigation.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"staros","vendor":"cisco"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"},{"id":"CWE-289","name":"Authentication Bypass by Alternate Name"}],"description":"A vulnerability in the key-based SSH authentication feature of Cisco StarOS Software could allow an authenticated, remote attacker to elevate privileges on an affected device.\r\n\r This vulnerability is due to insufficient validation of user-supplied credentials.
