NodeBB, published on 29 Sep 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-30591 exists.\n\nAffected product: NodeBB, Inc. NodeBB. 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-2023-30591/ (Markdown: https://insights.sbomify.com/CVE-2023-30591/index.md)","id":"CVE-2023-30591","markdown":"https://insights.sbomify.com/CVE-2023-30591/index.md","name":"CVE-2023-30591","record":{"aliases":["GHSA-mp98-q49w-jjhw"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NodeBB forum software","requires_auth":"none","summary":"Unauthenticated attackers can crash NodeBB by sending crafted Socket.IO messages with invalid event name types.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"STAR_Labs","cpe":[{"product":"nodebb","vendor":"nodebb"}],"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-754","name":"Improper Check for Unusual or Exceptional Conditions"},{"id":"CWE-241","name":"Improper Handling of Unexpected Data Type"}],"description":"Denial-of-service in NodeBB \u003c= v2.8.10 allows unauthenticated attackers to trigger a crash, when invoking `eventName.startsWith()` or `eventName.toString()`, while processing Socket.IO messages via crafted Socket.IO messages containing array or object type for the event name respectively.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"NodeBB Pre-Authentication Denial-of-Service","id":"CVE-2023-30591","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"Apache Cassandra: Privilege escalation when enabling FQL/Audit logs","id":"CVE-2023-30601"},"packages":[],"prev":{"headline":"Other in Node","id":"CVE-2023-30590"},"products":["NodeBB"],"published":"2023-09-29","related":[{"cvss_score":10,"headline":"NodeBB vulnerable to path traversal and code execution via prototype vulnerability","id":"CVE-2023-26045","kev_date_added":null,"published":"2023-07-24"},{"cvss_score":9.9,"headline":"Account takeover in NodeBB","id":"CVE-2020-15149","kev_date_added":null,"published":"2020-08-19"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-43187","kev_date_added":null,"published":"2023-09-26"},{"cvss_score":9.8,"headline":"API token verification can be bypassed","id":"CVE-2021-43786","kev_date_added":null,"published":"2021-11-29"},{"cvss_score":9.4,"headline":"Account takeover via prototype vulnerability","id":"CVE-2022-46164","kev_date_added":null,"published":"2022-12-05"},{"cvss_score":9,"headline":"Account takeover via cryptographically weak PRNG in NodeBB Forum","id":"CVE-2022-36045","kev_date_added":null,"published":"2022-08-31"},{"cvss_score":9,"headline":"XSS via prototype pollution","id":"CVE-2021-43787","kev_date_added":null,"published":"2021-11-29"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-23","vendors":["NodeBB, Inc."]},"summary":"Unauthenticated attackers can crash NodeBB by sending crafted Socket.IO messages with invalid event name types.","url":"https://insights.sbomify.com/CVE-2023-30591/"}
