Alpine: multiple traefik packages: security update to 2.2.8-r0

medium Tenable Self-Hosted Container Security Plugin ID 426400

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In Traefik before versions 1.7.26, 2.2.8, and 2.3.0-rc3, there exists a potential open redirect
 vulnerability in Traefik's handling of the "X-Forwarded-Prefix" header. The Traefik API dashboard
 component doesn't validate that the value of the header "X-Forwarded-Prefix" is a site relative path and
 will redirect to any header provided URI. Successful exploitation of an open redirect can be used to
 entice victims to disclose sensitive information. Active Exploitation of this issue is unlikely as it
 would require active header injection, however the Traefik team addressed this issue nonetheless to
 prevent abuse in e.g. cache poisoning scenarios. (CVE-2020-15129)
