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-2023-1894 in the wild and no public exploit code.\n\nAffected product: Puppet Puppet Enterprise. 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-2023-1894/ (Markdown: https://insights.sbomify.com/CVE-2023-1894/index.md)","id":"CVE-2023-1894","markdown":"https://insights.sbomify.com/CVE-2023-1894/index.md","name":"CVE-2023-1894","record":{"aliases":["DEBIAN-CVE-2023-1894","GHSA-x5cv-mqxq-8q96","UBUNTU-CVE-2023-1894"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Puppet Server","requires_auth":"none","summary":"Attackers can cause denial of service in Puppet Server by submitting crafted certificate names that trigger inefficient regular expression processing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"puppet","cpe":[{"product":"puppet_enterprise","vendor":"puppet"},{"product":"puppet_server","vendor":"puppet"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"A Regular Expression Denial of Service (ReDoS) issue was discovered in Puppet Server 7.9.2 certificate validation.
