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-2022-20933 in the wild and no public exploit code.\n\nAffected product: Cisco Meraki MX 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-2022-20933/ (Markdown: https://insights.sbomify.com/CVE-2022-20933/index.md)","id":"CVE-2022-20933","markdown":"https://insights.sbomify.com/CVE-2022-20933/index.md","name":"CVE-2022-20933","record":{"aliases":["GHSA-9vrx-xfr3-hfjj"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Meraki MX","requires_auth":"none","summary":"Unauthenticated remote attackers can crash the Cisco AnyConnect VPN server via malicious requests, causing service disruption and forcing user re-authentication.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"meraki_mx100_firmware","vendor":"cisco"},{"product":"meraki_mx105_firmware","vendor":"cisco"},{"product":"meraki_mx250_firmware","vendor":"cisco"},{"product":"meraki_mx400_firmware","vendor":"cisco"},{"product":"meraki_mx450_firmware","vendor":"cisco"},{"product":"meraki_mx600_firmware","vendor":"cisco"},{"product":"meraki_mx64_firmware","vendor":"cisco"},{"product":"meraki_mx64w_firmware","vendor":"cisco"},{"product":"meraki_mx65_firmware","vendor":"cisco"},{"product":"meraki_mx65w_firmware","vendor":"cisco"},{"product":"meraki_mx67_firmware","vendor":"cisco"},{"product":"meraki_mx67cw_firmware","vendor":"cisco"},{"product":"meraki_mx67w_firmware","vendor":"cisco"},{"product":"meraki_mx68_firmware","vendor":"cisco"},{"product":"meraki_mx68cw_firmware","vendor":"cisco"},{"product":"meraki_mx68w_firmware","vendor":"cisco"},{"product":"meraki_mx75_firmware","vendor":"cisco"},{"product":"meraki_mx84_firmware","vendor":"cisco"},{"product":"meraki_mx85_firmware","vendor":"cisco"},{"product":"meraki_mx95_firmware","vendor":"cisco"},{"product":"meraki_vmx_firmware","vendor":"cisco"},{"product":"meraki_z3_firmware","vendor":"cisco"},{"product":"meraki_z3c_firmware","vendor":"cisco"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-234","name":"Failure to Handle Missing Parameter"}],"description":"A vulnerability in the Cisco AnyConnect VPN server of Cisco Meraki MX and Cisco Meraki Z3 Teleworker Gateway devices could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient validation of client-supplied parameters while establishing an SSL VPN session. An attacker could exploit this vulnerability by crafting a malicious request and sending it to the affected device. A successful exploit could allow the attacker to cause the Cisco AnyConnect VPN server to crash and restart, resulting in the failure of the established SSL VPN connections and forcing remote users to initiate a new VPN connection and re-authenticate. A sustained attack could prevent new SSL VPN connections from being established. Note: When the attack traffic stops, the Cisco AnyConnect VPN server recovers gracefully without requiring manual intervention. Cisco Meraki has released software updates that address this vulnerability.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cisco Meraki MX and Z3 Teleworker Gateway VPN Denial of Service Vulnerability","id":"CVE-2022-20933","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in Cisco Firepower Extensible Operating System (FXOS)","id":"CVE-2022-20934"},"packages":[],"prev":{"headline":"Cross-site scripting in Cisco Firepower Management Center","id":"CVE-2022-20932"},"products":["Cisco Meraki MX Firmware"],"published":"2022-10-26","related":[{"cvss_score":8.6,"headline":"Denial of service in Cisco Meraki MX Firmware","id":"CVE-2024-20498","kev_date_added":null,"published":"2024-10-02"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Meraki MX Firmware","id":"CVE-2024-20499","kev_date_added":null,"published":"2024-10-02"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Meraki MX Firmware","id":"CVE-2024-20501","kev_date_added":null,"published":"2024-10-02"},{"cvss_score":5.8,"headline":"Denial of service in Cisco Meraki MX Firmware","id":"CVE-2024-20500","kev_date_added":null,"published":"2024-10-02"},{"cvss_score":5.8,"headline":"Denial of service in Cisco Meraki MX Firmware","id":"CVE-2024-20502","kev_date_added":null,"published":"2024-10-02"},{"cvss_score":5.8,"headline":"Race condition in Cisco Meraki MX Firmware","id":"CVE-2024-20509","kev_date_added":null,"published":"2024-10-02"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-01","vendors":["Cisco"]},"summary":"Unauthenticated remote attackers can crash the Cisco AnyConnect VPN server via malicious requests, causing service disruption and forcing user re-authentication.","url":"https://insights.sbomify.com/CVE-2022-20933/"}
