An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-20108 and fix it if it is affected.\n\nWhat it is: CVE-2023-20108 is a high-severity denial of service vulnerability in Cisco Unified Communications Manager IM and Presence Service, published on 28 Jun 2023. 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-2023-20108 in the wild and no public exploit code.\n\nAffected product: Cisco Unified Communications Manager IM and Presence Service. 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-2023-20108/ (Markdown: https://insights.sbomify.com/CVE-2023-20108/index.md)","id":"CVE-2023-20108","markdown":"https://insights.sbomify.com/CVE-2023-20108/index.md","name":"CVE-2023-20108","record":{"aliases":["GHSA-8937-gcf5-34xq"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Unified CM IM\u0026P","requires_auth":"none","summary":"An unauthenticated remote attacker can cause a denial of service by sending a crafted login message to the Cisco Unified CM IM\u0026P authentication service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"unified_communications_manager_im_and_presence_service","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"A vulnerability in the XCP Authentication Service of the Cisco Unified Communications Manager IM \u0026amp; Presence Service (Unified CM IM\u0026amp;P) could allow an unauthenticated, remote attacker to cause a temporary service outage for all Cisco Unified CM IM\u0026amp;P users who are attempting to authenticate to the service, resulting in a denial of service (DoS) condition.\r\n\r This vulnerability is due to improper validation of user-supplied input.
