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-2018-0234 in the wild and no public exploit code.\n\nAffected product: Cisco Aironet 1810, 1830, and 1850 Series Access Points. 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-2018-0234/ (Markdown: https://insights.sbomify.com/CVE-2018-0234/index.md)","id":"CVE-2018-0234","markdown":"https://insights.sbomify.com/CVE-2018-0234/index.md","name":"CVE-2018-0234","record":{"aliases":["GHSA-h937-x287-5g89"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Aironet Access Point","requires_auth":"none","summary":"Remote attackers can crash Cisco Aironet access points by sending malicious GRE frames, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"aironet_access_point_software","vendor":"cisco"}],"cvss":{"score":8.6,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the implementation of Point-to-Point Tunneling Protocol (PPTP) functionality in Cisco Aironet 1810, 1830, and 1850 Series Access Points could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of Generic Routing Encapsulation (GRE) frames that pass through the data plane of an affected access point. An attacker could exploit this vulnerability by initiating a PPTP connection to an affected access point from a device that is registered to the same wireless network as the access point and sending a malicious GRE frame through the data plane of the access point. A successful exploit could allow the attacker to cause the NSS core process on the affected access point to crash, which would cause the access point to reload and result in a DoS condition. This vulnerability affects Cisco Aironet 1810, 1830, and 1850 Series Access Points that are running Cisco Mobility Express Software Release 8.4.100.0, 8.5.103.0, or 8.5.105.0 and are configured as a master, subordinate, or standalone access point.
