CVE-2023-44487 31 Akka, Amazon, Apache and 28 more 127 Http Server, Opensearch Data Prepper, Apisix and 124 more 2023-12-20 N/A 7.5 HIGH
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
CVE-2023-47633 1 Traefik 1 Traefik 2023-12-07 N/A 7.5 HIGH
Traefik is an open source HTTP reverse proxy and load balancer. The traefik docker container uses 100% CPU when it serves as its own backend, which is an automatically generated route resulting from the Docker integration in the default configuration. This issue has been addressed in versions 2.10.6 and 3.0.0-beta5. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2021-32813 1 Traefik 1 Traefik 2021-08-11 6.8 MEDIUM 8.1 HIGH
Traefik is an HTTP reverse proxy and load balancer. Prior to version 2.4.13, there exists a potential header vulnerability in Traefik's handling of the Connection header. Active exploitation of this issue is unlikely, as it requires that a removed header would lead to a privilege escalation, however, the Traefik team has addressed this issue to prevent any potential abuse. If one has a chain of Traefik middlewares, and one of them sets a request header, then sending a request with a certain Connection header will cause it to be removed before the request is sent. In this case, the backend does not see the request header. A patch is available in version 2.4.13. There are no known workarounds aside from upgrading.
CVE-2018-15598 1 Traefik 1 Traefik 2021-07-28 5.0 MEDIUM 7.5 HIGH
Containous Traefik 1.6.x before 1.6.6, when --api is used, exposes the configuration and secret if authentication is missing and the API's port is publicly reachable.
CVE-2020-9321 1 Traefik 1 Traefik 2021-07-28 5.0 MEDIUM 7.5 HIGH
configurationwatcher.go in Traefik 2.x before 2.1.4 and TraefikEE 2.0.0 mishandles the purging of certificate contents from providers before logging.
CVE-2019-12452 1 Traefik 1 Traefik 2021-07-28 3.5 LOW 7.5 HIGH
types/types.go in Containous Traefik 1.7.x through 1.7.11, when the --api flag is used and the API is publicly reachable and exposed without sufficient access control (which is contrary to the API documentation), allows remote authenticated users to discover password hashes by reading the Basic HTTP Authentication or Digest HTTP Authentication section, or discover a key by reading the ClientTLS section. These can be found in the JSON response to a /api request.
CVE-2019-20894 1 Traefik 1 Traefik 2021-07-28 4.3 MEDIUM 7.5 HIGH
Traefik 2.x, in certain configurations, allows HTTPS sessions to proceed without mutual TLS verification in a situation where ERR_BAD_SSL_CLIENT_AUTH_CERT should have occurred.
