PRIOn knowledge basePRION:CVE-2023-47124Code injection
Traefik is an open source HTTP reverse proxy and load balancer. 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.
