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-2024-20500 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-2024-20500/ (Markdown: https://insights.sbomify.com/CVE-2024-20500/index.md)","id":"CVE-2024-20500","markdown":"https://insights.sbomify.com/CVE-2024-20500/index.md","name":"CVE-2024-20500","record":{"aliases":["GHSA-7pgw-6p7m-45vf"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Meraki MX Firmware","requires_auth":"none","summary":"Unauthenticated remote attackers can cause a denial of service in the Cisco AnyConnect VPN server by sending crafted TLS/SSL messages, blocking new connections.","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_mx67c_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"},{"product":"meraki_z4_firmware","vendor":"cisco"},{"product":"meraki_z4c_firmware","vendor":"cisco"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability in the Cisco AnyConnect VPN server of Cisco Meraki MX and Cisco Meraki Z Series Teleworker Gateway devices could allow an unauthenticated, remote attacker to cause a DoS condition in the AnyConnect service on an affected device.\r\n\n This vulnerability is due to insufficient resource management when establishing TLS/SSL sessions. An attacker could exploit this vulnerability by sending a series of crafted TLS/SSL messages to the VPN server of an affected device. A successful exploit could allow the attacker to cause the Cisco AnyConnect VPN server to stop accepting new connections, preventing new SSL VPN connections from being established. Existing SSL VPN sessions are not impacted.\r\n\n Note: When the attack traffic stops, the Cisco AnyConnect VPN server recovers gracefully without requiring manual intervention.","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":"Denial of service in Cisco Meraki MX Firmware","id":"CVE-2024-20500","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in Cisco Meraki MX Firmware","id":"CVE-2024-20501"},"packages":[],"prev":{"headline":"Denial of service in Cisco Meraki MX Firmware","id":"CVE-2024-20499"},"products":["Cisco Meraki MX Firmware"],"published":"2024-10-02","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":8.6,"headline":"Cisco Meraki MX and Z3 Teleworker Gateway VPN Denial of Service Vulnerability","id":"CVE-2022-20933","kev_date_added":null,"published":"2022-10-26"},{"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":"2025-06-04","vendors":["Cisco"]},"summary":"Unauthenticated remote attackers can cause a denial of service in the Cisco AnyConnect VPN server by sending crafted TLS/SSL messages, blocking new connections.","url":"https://insights.sbomify.com/CVE-2024-20500/"}
