Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-23184 in the wild and no public exploit code.\n\nAffected product: Open-Xchange GmbH OX Dovecot Pro. 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-2024-23184/ (Markdown: https://insights.sbomify.com/CVE-2024-23184/index.md)","id":"CVE-2024-23184","markdown":"https://insights.sbomify.com/CVE-2024-23184/index.md","name":"CVE-2024-23184","record":{"aliases":["ALPINE-CVE-2024-23184","AZL-48981","AZL-49024","CLSA-2025-1753374470","DEBIAN-CVE-2024-23184","GHSA-5f48-j349-fj3m","UBUNTU-CVE-2024-23184"],"analysis":{"component_type":"server_software","fix_type":"configuration_change","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Dovecot mail server","requires_auth":"low_privilege","summary":"An attacker can cause denial of service by sending emails with excessive address headers, consuming CPU resources on Dovecot servers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Having a large number of address headers (From, To, Cc, Bcc, etc.) becomes excessively CPU intensive.

An external attacker can send specially crafted messages that consume target system resources and cause outage. One can implement restrictions on address headers on MTA component preceding Dovecot.
