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-2017-6620 in the wild and no public exploit code.\n\nAffected product: Cisco CVR100W Wireless-N VPN Router. 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-2017-6620/ (Markdown: https://insights.sbomify.com/CVE-2017-6620/index.md)","id":"CVE-2017-6620","markdown":"https://insights.sbomify.com/CVE-2017-6620/index.md","name":"CVE-2017-6620","record":{"aliases":["GHSA-rchj-ffxp-rrv5"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco VPN Router","requires_auth":"none","summary":"Unauthenticated attackers can bypass remote management ACLs on Cisco CVR100W routers when remote management is disabled, gaining unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"small_business_rv_series_router_firmware","vendor":"cisco"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-264","name":null}],"description":"A vulnerability in the remote management access control list (ACL) feature of the Cisco CVR100W Wireless-N VPN Router could allow an unauthenticated, remote attacker to bypass the remote management ACL. The vulnerability is due to incorrect implementation of the ACL decision made during the ingress connection request to the remote management interface. An attacker could exploit this vulnerability by sending a connection to the management IP address or domain name of the targeted device. A successful exploit could allow the attacker to bypass the configured remote management ACL. This can occur when the Remote Management configuration parameter is set to Disabled.
