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-2023-20259 in the wild and no public exploit code.\n\nAffected product: Cisco Unified Communications Manager. 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-2023-20259/ (Markdown: https://insights.sbomify.com/CVE-2023-20259/index.md)","id":"CVE-2023-20259","markdown":"https://insights.sbomify.com/CVE-2023-20259/index.md","name":"CVE-2023-20259","record":{"aliases":["GHSA-x67r-8jfc-3r5m"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Unified Communications","requires_auth":"none","summary":"Unauthenticated remote attackers can cause high CPU utilization and denial of service in Cisco Unified Communications products via crafted HTTP requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"emergency_responder","vendor":"cisco"},{"product":"prime_collaboration_deployment","vendor":"cisco"},{"product":"unified_communications_manager","vendor":"cisco"},{"product":"unified_communications_manager_im_\\\u0026_presence_service","vendor":"cisco"},{"product":"unity_connection","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-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability in an API endpoint of multiple Cisco Unified Communications Products could allow an unauthenticated, remote attacker to cause high CPU utilization, which could impact access to the web-based management interface and cause delays with call processing. This API is not used for device management and is unlikely to be used in normal operations of the device.\r\n\r This vulnerability is due to improper API authentication and incomplete validation of the API request. An attacker could exploit this vulnerability by sending a crafted HTTP request to a specific API on the device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition due to high CPU utilization, which could negatively impact user traffic and management access. When the attack stops, the device will recover without 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 Emergency Responder","id":"CVE-2023-20259","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:unified_communications_manager","products":["cisco:unified_communications_manager","cisco:unity_connection"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Cisco Evolved Programmable Network Manager (EPNM)","id":"CVE-2023-20260"},"packages":[],"prev":{"headline":"Deserialization in Cisco Prime Infrastructure","id":"CVE-2023-20258"},"products":["Cisco Emergency Responder","Cisco Prime Collaboration Deployment","Cisco Unified Communications Manager","Cisco Unified Communications Manager IM and Presence Service","Cisco Unity Connection"],"published":"2023-10-04","related":[{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2008-1154","kev_date_added":null,"published":"2008-04-04"},{"cvss_score":9.8,"headline":"Hardcoded credentials in Cisco Emergency Responder","id":"CVE-2023-20101","kev_date_added":null,"published":"2023-10-04"},{"cvss_score":9.8,"headline":"Hardcoded credentials in Cisco Voice Operating System","id":"CVE-2017-12337","kev_date_added":null,"published":"2017-11-16"},{"cvss_score":8.8,"headline":"Cross-site request forgery in Cisco Emergency Responder","id":"CVE-2016-6468","kev_date_added":null,"published":"2016-12-14"},{"cvss_score":7.5,"headline":"Denial of service in Multiple Cisco Products unknown","id":"CVE-2017-6779","kev_date_added":null,"published":"2018-06-07"},{"cvss_score":6.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2015-6405","kev_date_added":null,"published":"2015-12-13"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-02","vendors":["Cisco"]},"summary":"Unauthenticated remote attackers can cause high CPU utilization and denial of service in Cisco Unified Communications products via crafted HTTP requests.","url":"https://insights.sbomify.com/CVE-2023-20259/"}
