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-2020-3357 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-2020-3357/ (Markdown: https://insights.sbomify.com/CVE-2020-3357/index.md)","id":"CVE-2020-3357","markdown":"https://insights.sbomify.com/CVE-2020-3357/index.md","name":"CVE-2020-3357","record":{"aliases":["GHSA-x7v4-2v57-r86h"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco RV Series Router","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary code or cause denial of service on Cisco RV Series routers via crafted SSL requests.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"rv340_dual_wan_gigabit_vpn_router_firmware","vendor":"cisco"},{"product":"rv340w_dual_wan_gigabit_wireless-ac_vpn_router_firmware","vendor":"cisco"},{"product":"rv345_dual_wan_gigabit_vpn_router_firmware","vendor":"cisco"},{"product":"rv345p_dual_wan_gigabit_poe_vpn_router_firmware","vendor":"cisco"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the Secure Sockets Layer (SSL) VPN feature of Cisco Small Business RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device or cause the device to reload, resulting in a denial of service (DoS) condition.
