When Traefik is configured to use the `HTTPChallenge` to generate and renew the Let's Encrypt TLS certificates, the delay authorized to solve the challenge (50 seconds) can be exploited by attackers to achieve a `slowloris attack`. This vulnerability has been patch in version 2.10.6 and 3.0.0-beta5. Users are advised to upgrade. Users unable to upgrade should replace the `HTTPChallenge` with the `TLSChallenge` or the `DNSChallenge`."}],"source":{"advisory":"GHSA-8g85-whqh-cr2f","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T21:01:22.848Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/traefik/traefik/security/advisories/GHSA-8g85-whqh-cr2f","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/traefik/traefik/security/advisories/GHSA-8g85-whqh-cr2f"},{"name":"https://doc.traefik.io/traefik/https/acme/#dnschallenge","tags":["x_refsource_MISC","x_transferred"],"url":"https://doc.traefik.io/traefik/https/acme/#dnschallenge"},{"name":"https://doc.traefik.io/traefik/https/acme/#httpchallenge","tags":["x_refsource_MISC","x_transferred"],"url":"https://doc.traefik.io/traefik/https/acme/#httpchallenge"},{"name":"https://doc.traefik.io/traefik/https/acme/#tlschallenge","tags":["x_refsource_MISC","x_transferred"],"url":"https://doc.traefik.io/traefik/https/acme/#tlschallenge"},{"name":"https://github.com/traefik/traefik/releases/tag/v2.10.6","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/traefik/traefik/releases/tag/v2.10.6"},{"name":"https://github.com/traefik/traefik/releases/tag/v3.0.0-beta5","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/traefik/traefik/releases/tag/v3.0.0-beta5"},{"name":"ttps://www.cloudflare.com/learning/ddos/ddos-attack-tools/slowloris/","tags":["x_refsource_MISC","x_transferred"],"url":"ttps://www.cloudflare.com/learning/ddos/ddos-attack-tools/slowloris/"}]}]}}
