An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-20026 in the wild and no public exploit code.\n\nAffected product: Cisco Small Business RV Series Router Firmware. 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-2023-20026/ (Markdown: https://insights.sbomify.com/CVE-2023-20026/index.md)","id":"CVE-2023-20026","markdown":"https://insights.sbomify.com/CVE-2023-20026/index.md","name":"CVE-2023-20026","record":{"aliases":["GHSA-f3r5-v4wr-72qr"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Small Business Router","requires_auth":"high_privilege","summary":"Authenticated attackers can execute arbitrary commands with root privileges on Cisco Small Business RV Series Routers via the web interface.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"rv016_firmware","vendor":"cisco"},{"product":"rv042_firmware","vendor":"cisco"},{"product":"rv042g_firmware","vendor":"cisco"},{"product":"rv082_firmware","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"A vulnerability in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320 and RV325 Routers could allow an authenticated, remote attacker to execute arbitrary commands on an affected device.\r\n\r This vulnerability is due to improper validation of user input within incoming HTTP packets.
