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-2024-20513 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-2024-20513/ (Markdown: https://insights.sbomify.com/CVE-2024-20513/index.md)","id":"CVE-2024-20513","markdown":"https://insights.sbomify.com/CVE-2024-20513/index.md","name":"CVE-2024-20513","record":{"aliases":["GHSA-45f4-7wmp-8679"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Meraki MX Firmware","requires_auth":"none","summary":"An attacker can terminate targeted SSL VPN sessions on Cisco Meraki devices by predicting session handlers, forcing users to reconnect.","user_interaction":"not_required","vuln_class":"other"},"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-639","name":"Authorization Bypass Through User-Controlled Key"}],"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 for targeted users of the AnyConnect service on an affected device.\r\n\n This vulnerability is due to insufficient entropy for handlers that are used during SSL VPN session establishment. An unauthenticated attacker could exploit this vulnerability by brute forcing valid session handlers. An authenticated attacker could exploit this vulnerability by connecting to the AnyConnect VPN service of an affected device to retrieve a valid session handler and, based on that handler, predict further valid session handlers. The attacker would then send a crafted HTTPS request using the brute-forced or predicted session handler to the AnyConnect VPN server of the device. A successful exploit could allow the attacker to terminate targeted SSL VPN sessions, forcing remote users to initiate new VPN connections and reauthenticate.","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":"Other in Cisco Meraki MX Firmware","id":"CVE-2024-20513","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Evolved Programmable Network Manager and Cisco Prime Infrastructure Stored Cross-Site Scripting Vulnerability","id":"CVE-2024-20514"},"packages":[],"prev":{"headline":"Cisco Unified Contact Center Management Portal Reflected Cross-Site Scripting Vulnerability","id":"CVE-2024-20512"},"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-2024-20500","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-04","vendors":["Cisco"]},"summary":"An attacker can terminate targeted SSL VPN sessions on Cisco Meraki devices by predicting session handlers, forcing users to reconnect.","url":"https://insights.sbomify.com/CVE-2024-20513/"}
