{"cve":"CVE-2024-28854","nvd":{"published":"2024-03-15T19:15:07.627","modified":"2026-06-17T07:21:53.827","status":"Analyzed","description":"tls-listener is a rust lang wrapper around a connection listener to support TLS. With the default configuration of tls-listener, a malicious user can open 6.4 `TcpStream`s a second, sending 0 bytes, and can trigger a DoS. The default configuration options make any public service using `TlsListener::new()` vulnerable to a slow-loris DoS attack. This impacts any publicly accessible service using the default configuration of tls-listener in versions prior to 0.10.0. Users are advised to upgrade. Users unable to upgrade may mitigate this by passing a large value, such as `usize::MAX` as the parameter to `Builder::max_handshakes`.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["https://en.wikipedia.org/wiki/Slowloris_(computer_security)","https://github.com/tmccombs/tls-listener/commit/d5a7655d6ea9e53ab57c3013092c5576da964bc4","https://github.com/tmccombs/tls-listener/security/advisories/GHSA-2qph-qpvm-2qf7","https://en.wikipedia.org/wiki/Slowloris_(computer_security)","https://github.com/tmccombs/tls-listener/commit/d5a7655d6ea9e53ab57c3013092c5576da964bc4"],"products":["tmccombs:tls-listener"],"source":"nvd","synced_at":"2026-10-19T21:46:54.846886191+00:00"},"epss":{"cve":"CVE-2024-28854","score":0.00973,"percentile":0.61992,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-2qph-qpvm-2qf7","url":"https://osv.dev/vulnerability/GHSA-2qph-qpvm-2qf7","summary":"tls-listener affected by the slow loris vulnerability with default configuration","modified":"2026-09-10T03:50:00.245355007Z","packages":[{"ecosystem":"crates.io","name":"tls-listener","purl":"pkg:cargo/tls-listener","ranges":["<0.10.0"],"fixed":["0.10.0"]}]},{"id":"RUSTSEC-2024-0341","url":"https://osv.dev/vulnerability/RUSTSEC-2024-0341","summary":"Slow loris vulnerability with default configuration","modified":"2026-10-12T18:00:02.661145894Z","packages":[{"ecosystem":"crates.io","name":"tls-listener","purl":"pkg:cargo/tls-listener","ranges":[">=0.0.0-0 <0.10.0"],"fixed":["0.10.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
